Expression of an Aspergillus niger phytase gene (phyA) in Saccharomyces cerevisiae. (1/247)

Phytase improves the bioavailability of phytate phosphorus in plant foods to humans and animals and reduces phosphorus pollution of animal waste. Our objectives were to express an Aspergillus niger phytase gene (phyA) in Saccharomyces cerevisiae and to determine the effects of glycosylation on the phytase's activity and thermostability. A 1.4-kb DNA fragment containing the coding region of the phyA gene was inserted into the expression vector pYES2 and was expressed in S. cerevisiae as an active, extracellular phytase. The yield of total extracellular phytase activity was affected by the signal peptide and the medium composition. The expressed phytase had two pH optima (2 to 2.5 and 5 to 5.5) and a temperature optimum between 55 and 60 degrees C, and it cross-reacted with a rabbit polyclonal antibody against the wild-type enzyme. Due to the heavy glycosylation, the expressed phytase had a molecular size of approximately 120 kDa and appeared to be more thermostable than the commercial enzyme. Deglycosylation of the phytase resulted in losses of 9% of its activity and 40% of its thermostability. The recombinant phytase was effective in hydrolyzing phytate phosphorus from corn or soybean meal in vitro. In conclusion, the phyA gene was expressed as an active, extracellular phytase in S. cerevisiae, and its thermostability was affected by glycosylation.  (+info)

Phytase improves iron bioavailability for hemoglobin synthesis in young pigs. (2/247)

Dietary phytase supplementation improves bioavailabilities of phytate-bound minerals such as P, Ca, and Zn to pigs, but its effect on Fe utilization is not clear. The efficacy of phytase in releasing phytate-bound Fe and P from soybean meal in vitro and in improving dietary Fe bioavailability for hemoglobin repletion in young, anemic pigs was examined. In Exp. 1, soybean meal was incubated at 37 degrees C for 4 h with either 0, 400, 800, or 1,200 units (U) of phytase/kg, and the released Fe and P concentrations were determined. In Exp. 2, 12 anemic, 21-d-old pigs were fed either a strict vegetarian, high-phytate (1.34%) basal diet alone, or the diet supplemented with 50 mg Fe/kg diet (ferrous sulfate) or phytase at 1,200 U/kg diet (Natuphos, BASF, Mt. Olive, NJ) for 4 wk. In Exp. 3, 20 anemic, 28-d-old pigs were fed either a basal diet with a moderately high phytate concentration (1.18%) and some animal protein or the diet supplemented with 70 mg Fe/kg diet, or with one of two types of phytase (Natuphos or a new phytase developed in our laboratory, 1,200 U/kg diet) for 5 wk. In Exp. 2 and 3, diets supplemented with phytase contained no inorganic P. In Exp. 1, free P concentrations in the supernatant increased in a phytase dose-dependent fashion (P<.05), whereas free Fe concentrations only increased at the dose of 1,200 U/kg (P<.10). In Exp. 2 and 3, dietary phytase increased hemoglobin concentrations and packed cell volumes over the unsupplemented group; these two measures, including growth performance, were not significantly different than those obtained with dietary supplemental Fe. In conclusion, both sources of phytase effectively degraded phytate in corn-soy diets and subsequently released phytate-bound Fe from the diets for hemoglobin repletion in young, anemic pigs.  (+info)

Occupational IgE sensitisation to phytase, a phosphatase derived from Aspergillus niger. (3/247)

OBJECTIVE: Phytase is a phosphatase derived from Aspergillus niger that enhances phosphate bioavailability in the gut, and therefore has been increasingly used as an animal feed additive since the early 1990s. The aim of this study was to assess whether work related respiratory symptoms among workers in a so called premix factory producing animal feed additives, could be due to type I (mediated by immunoglobulin E (IgE) allergic sensitisation to phytase. METHODS: Preparations of specific IgE against phytase as used in the factory were assessed by enzyme immunoassay (EIA) in serum samples of 11 exposed workers who regularly handled the enzyme, in 11 office and laboratory workers of the same plant (non-exposed internal controls), and in 19 laboratory animal workers as external controls. The factory workers also completed a questionnaire on common and work related respiratory symptoms. RESULTS: Depending on the cut off level in the EIA for IgE, and the preparation used as coated allergen, antiphytase sensitisation was found in one to four of the 19 external controls, in one to five of the 11 internal controls, and in four to 10 of the 11 exposed workers. Strongest IgE reactions were found in four exposed workers who reported work related respiratory symptoms, particularly wheezing, and in one internal control who possibly had become sensitised because the structure of the factory building did not preclude airborne exposure in the offices and corridors of the plant. Experiments with inhibition EIA for IgE showed that (a) phytase of another commercial source was only partially cross reactive with phytase as used in the premix factory, and (b) phytase used as an animal feed additive did not cross react with common mould extracts, except for extracts from the species of origin, Aspergillus niger. The amount of IgE binding phytase in Aspergillus niger was estimated to be between 0.1% and 1% of the extractable mould proteins. CONCLUSIONS: Phytase is a potentially important new occupational allergen causing specific IgE immune responses among exposed workers. Such IgE sensitisation could probably be the cause of work related asthmatic and other respiratory symptoms if no effective measures are taken to prevent airborne occupational exposure at sites where phytase is handled, particularly during addition of enzyme preparations to animal feed.  (+info)

Dephosphorylation of phytate by using the Aspergillus niger phytase with a high affinity for phytate. (4/247)

A phytase (EC with a high affinity for phytic acid was found in Aspergillus niger SK-57 and purified to homogeneity in four steps by using ion-exchange chromatography (two types), gel filtration, and chromatofocusing. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the purified enzyme gave a single stained band at a molecular mass of approximately 60 kDa. The Michaelis constant of the enzyme for phytic acid (18.7 +/- 4.6 microM) was statistically analyzed. In regard to the orthophosphate released from phytic acid, a significant difference between a low K(m) phytase from A. niger SK-57 and a high K(m) phytase from Aspergillus ficuum was recognized.  (+info)

Comparative enzymatic hydrolysis of phytate in various animal feedstuff with two different phytases. (5/247)

Bacillus amyloliquefaciens DS11 phytase (DS11 phytase) and Aspergillus ficuum phytase (AF phytase) activities were investigated by measuring the release of phosphate from phytate in animal feedstuff such as wheat bran, corn meal, soybean meal and rice flour at pH 5 and 7. In all the tested feedstuff, the enzymatic activity of DS11 phytase was more active at pH 7, but that of AF phytase was more active at pH 5. From these results, the phytate in the gastrointestinal tract could be degraded in the small intestine or stomach by DS11 or AF phytase, respectively. In conclusion, the results presented in this paper indicated that different combination ratios of DS11 and AF phytase, depending on the kind of feedstuff, might effectively induce more enzymatic activity both in the stomach and small intestine in terms of the pH of the gastrointestinal tract.  (+info)

From DNA sequence to improved functionality: using protein sequence comparisons to rapidly design a thermostable consensus phytase. (6/247)

Naturally-occurring phytases having the required level of thermostability for application in animal feeding have not been found in nature thus far. We decided to de novo construct consensus phytases using primary protein sequence comparisons. A consensus enzyme based on 13 fungal phytase sequences had normal catalytic properties, but showed an unexpected 15-22 degrees C increase in unfolding temperature compared with each of its parents. As a first step towards understanding the molecular basis of increased heat resistance, the crystal structure of consensus phytase was determined and compared with that of Aspergillus niger phytase. Aspergillus niger phytase unfolds at much lower temperatures. In most cases, consensus residues were indeed expected, based on comparisons of both three-dimensional structures, to contribute more to phytase stabilization than non-consensus amino acids. For some consensus amino acids, predicted by structural comparisons to destabilize the protein, mutational analysis was performed. Interestingly, these consensus residues in fact increased the unfolding temperature of the consensus phytase. In summary, for fungal phytases apparently an unexpected direct link between protein sequence conservation and protein stability exists.  (+info)

Efficacy of yeast phytase in improving phosphorus bioavailability in a corn-soybean meal-based diet for growing pigs. (7/247)

Crossbred barrows (n = 66; 6 wk old) were used in a 6-wk experiment to evaluate the efficacy of phytase from yeast or Aspergillus niger on performance, tibial characteristics, and serum inorganic P concentration. We also investigated the stability of these phytases in acidic solutions with pepsin, which simulated gastric conditions. Pigs were fed a P-adequate diet containing .34% nonphytate-P or a low-P diet containing .20% nonphytate-P. The low-P diet was supplemented with 0, 1,000, 2,000, or 4,000 phytase units (PU; the activity at optimal pH, i.e., pH 4.2 for yeast phytase and pH 5.5 for phytase from Aspergillus niger)/kg of yeast phytase, or 1,000 PU/kg phytase from Aspergillus niger. The graded level of yeast phytase linearly increased ADG (P = .047), tibial weight (P = .091), tibial density (P < .001), and P concentration in tibial cortex (P = .018). Aspergillus niger phytase also increased ADG (P = .022), serum inorganic P concentration (P < .001), tibial density (P = .007), and tibial P concentration (P = .025). The pigs given 1,000 PU/kg Aspergillus niger phytase showed greater ADG (P = .091), tibial density (P= .001), and tibial P concentration (P = .062) than those given 1,000 PU/kg yeast phytase. No measurements differed (P > .31) between the pigs given 1,000 PU/kg Aspergillus niger phytase and those given 4,000 PU/kg yeast phytase. These results suggested that yeast phytase improves bioavailability of P in the diet for growing pigs but the efficacy of yeast phytase is less than that of Aspergillus niger phytase. During incubation in acidic solutions with pepsin, yeast phytase (P < .001) lost more of its activity than Aspergillus niger phytase. This lesser stability of yeast phytase may be responsible for the poorer efficacy of yeast phytase than that of Aspergillus niger. In summary, supplementation of swine diets with yeast phytase is beneficial, but its efficacy is less than that of Aspergillus niger phytase.  (+info)

Effects of dietary calcium:phosphorus ratios on apparent absorption of calcium and phosphorus in the small intestine, cecum, and colon of pigs. (8/247)

Thirty-two crossbred barrows were used to investigate the effects of dietary Ca:total P (tP) ratios in phytase-supplemented diets on the apparent absorption of P and Ca in the small intestine, cecum, and colon. Three Ca:tP ratio treatments (1.5:1, 1.3:1, or 1.0:1) were created by adjusting the amount of ground limestone added to the basal low-P grower (.39% tP including .07% added inorganic P) and finisher (.32% tP without added inorganic P) diets. All low-P ratio diets were supplemented with Natuphos phytase at 500 units/kg. A positive control diet without phytase supplementation contained adequate P and Ca to meet dietary requirements. At 123 kg, the pigs were slaughtered and the contents of ileum, cecum, and colon were collected. Lowering the dietary Ca:tP ratio in the diets containing phytase linearly increased (P < .01) the apparent absorption (% and g/d) of P in the small intestine, but Ca absorption was not affected. Pigs fed the low-P diet with a Ca:tP ratio of 1.0:1 had an apparent absorption (g/d) of P or Ca similar to that of pigs fed the control diet, which was adequate in Ca and P. Averaged across all diets, the apparent absorption of P was highest when measured at the cecum, and the apparent absorption of Ca was highest when measured at the colon. In conclusion, lowering the dietary Ca:tP ratio to 1.0:1 in a low-P diet containing phytase increased the apparent absorption of P in the small intestine. Furthermore, a significant amount of P was absorbed in the cecum.  (+info)

Three barrows weighing 45.0 kg, fitted with simple T-cannulas in both the duodenum and terminal ileum, were assigned to diets in a 3횞3 Latin Square design experiment to determine the effects of two calcium levels (0.8% vs 0.4%) on phytase activity and nutrient balance in growing pigs. The control diet contained 0.8% calcium, with no added inorganic phosphorus (0.45% total phosphorus) and no added phytase. The two additional experimental diets contained microbial phytase (750 phytase units/kg) and supplied either 0.8% or 0.4% calcium. With added microbial phytase, ileal and total tract digestibility of total phosphorus were improved by 20.9 and 13.8 percentage units, respectively (p=0.01). The apparent duodenal and ileal digestibility of phytate phosphorus were increased by 51.8 and 49.7 percentage units. (p=0.001). Lowering dietary calcium in the presence of microbial phytase increased the digestibility of phytate phosphorus by an additional 10.9 (p=0.001) and 5.7 percentage units for duodenal ...
Phytate is considered as one of the antinutritional factors exist mainly in different plants; it chelates many nutrition factors and denaturing many proteins. Recent research dealed with the isolation of extracellular phytase producing Bacillus species from local soil samples; the effect of phytase on different sources of phytate. Twenty five bacterial isolates of Bacillus species produced extracellular phytase on pikovaskaya agar or phytase screening medium( PSM). The clear zone around bacterial growth indicated for enzyme production. Soil samples were collected from many agricultural region includes Baghdad, Karballa, Babylon, Basrah, Emarah and al- Sulaimania. Five bacterial isolates had the ability to digest phytate extracted from different sources such as wheat bran, barly, rice bran, chick bea, mung bean, grass bea and phasolias. Other bacterial isolates could digest some of phytate sources. Extracellular phytase activity were determined at different pHs buffer for five chosen isolates using
Weaned crossbred barrows (n=126) were used to investigate the effect of four different levels of a new Zymetrics Inc. phytase (100 Units (U); 500 U; 2,500 U; or 12,500 U) on low phosphorus corn-soybean meal diets. This tested the theory that supplementation of higher phytase amounts to a low phosphorus diet will increase bone strength as well as maintain growth performance at a higher rate than those of lower or no phytase supplementation. Pigs were adjusted to a common Phase I diet for two weeks post-weaning before allocation to 1 of 6 dietary treatments for 4 weeks. Increasing supplemental phytase showed a linear increase in ADG (p , .01) and also showed an linear increase in overall body weight (BW) during the growing and finishing stages of the experiment. Daily feed intake and feed efficiency showed a linear increase (p , .01) and overall breaking strength increased linearly with phytase supplementation. Gain to feed ratios in pigs with 2,500 U and 12,500 U showed better performance than ...

Phytase is a phosphatase enzyme widely used as feed additive to release inorganic phosphorus from plant phytate and enhance its uptake in monogastric animals. Although engineered fungal phytases are used most, a natural enzyme gives opportunity to understand novel properties, if any. In the current study, a novel fungal strain, Aspergillus foetidus MTCC 11682 was immobilized on poly urethane cubes and used for phytase production, purification and molecular characterization. Phytase produced by this method was partially purified by ammonium sulphate precipitation and Sephacryl S-200HR gel filtration to 23.4-fold (compared to crude extract) with recovery of 13% protein. Electrophoresis analysis revealed that phytase has molecular weight of 90.5 kDa on non-reducing and 129.6 kDa on reducing SDS-PAGE. The purified phytase exhibited a wider pH and temperature stability. Analysis of the cloned sequence showed that the gene has 1176 bp that encodes for a peptide of 391 amino acids of the core catalytic region.
The use of genetically engineered probiotics to express specific enzymes has been the subject of considerable attention in poultry industry because of increased nutrient availability and reduced cost of enzyme supplementation. Phytase enzyme is commonly added to poultry feed to improve digestibility and availability of phosphorus from plant sources. To construct a probiotic with potential of phytate degradation, phytase gene (appA) from E. coli was cloned and transformed into two probiotic bacteria Lactobacillus salivarius and Lactococcus lactis. The results showed plasmid instability, unable to express the gene. The expression of appA gene in L. lactis was analyzed by detecting specific RNA and zymography assay. Phytase enzyme was isolated from cellular extracts of recombinant L. lactis, showing a 46 kDa band upon the SDS-PAGE analysis. Zymogram also confirmed the phytase activity of the 46 kDa band corresponding to the enzyme. An enzyme activity of 4.9 U mL-1 was obtained in cell extracts of L. lactis
Recently, we engineered Pichia pastoris Muts strains to produce several beta-propeller phytases, one from Bacillus subtilis and the others designed by a structure-guided consensus approach. Furthermore, we demonstrated the ability of P. pastoris to produce and secrete these phytases in an active form in shake-flask cultures. In the present work, we used a design of experiments strategy (Simplex optimization method) to optimize five environmental factors that define the culture conditions in the induction step to increase beta-propeller phytase production in P. pastoris bioreactor cultures. With the optimization process, up to 347,682 U (82,814 U/L or 6.4 g/L culture medium) of phytase at 68 h of induction was achieved. In addition, the impact of the optimization process on the physiological response of the host was evaluated. The results indicate that the increase in extracellular phytase production through the optimization process was correlated with an increase in metabolic activity of P. ...

Phytase supplementation in broiler diets is a common practice to improve phosphorus (P) availability and to reduce P loss by excretion. An enhanced P availability, and its concomitant supplementation with calcium (Ca), can affect the structure of the microbial community in the digestive tract of broiler chickens. Here, we aim to distinguish the effects of mineral P, Ca, and phytase on the composition of microbial communities present in the content and the mucosa layer of the gastrointestinal tract (GIT) of broiler chickens. Significant differences were observed between digesta and mucosa samples for the GIT sections studied (p= 0.001). The analyses of 56 individual birds showed a high microbial composition variability within the replicates of the same diet. The average similarity within replicates of digesta and mucosa samples across all diets ranged from 29 to 82% in crop, 19-49% in ileum, and 17-39% in caeca. Broilers fed with a diet only supplemented with Ca had the lowest body weight gain ...
The event, themed The Value Chain of Phytate Destruction, has seen feed and nutrition experts from around the world share the latest research into how combatting phytate can improve feed efficiency, nutrient utilisation, sustainability and ultimately profitability.. On the final day, Professor Hank Classen, University of Saskatchewan, highlighted the impact of phytate and phytate esters on protein digestibility and the influence of superdoses of phytase on amino acid digestibility, specifically non-essential amino acids.. The use of high levels of phytase is promising in young birds because we did see a more consistent response in phytate hydrolysis and so the availability of amino acids and energy is also more predictable.. Professor Layi Adeola of Purdue University discussed the fate of amino acids in the gastrointestinal tract, a very complex system of endogenous enzymes and transporters.. This research was followed by that of Dr Sami Dridi, University of Arkansas, and Dr Gabriel Morales, ...

The patients medical history, bibasal lung crackles at auscultation, the restrictive lung function pattern with decreased diffusion capacity for carbon monoxide, oxygen tension decrease on exertion, radiological features, increased specific IgG to phytase, and the positive exposure test (including the BAL results), all support the diagnosis of hypersensitivity pneumonitis (HP) 5-7. Furthermore, the clinical improvement after treatment and cessation of the contact to phytase strongly suggest HP due to inhalation of phytase. To the best of our knowledge, this has never been reported before.. Phytase is an enzyme that catalyses the hydrolysis of phytate, a phosphate-storage mode present in cereals and soy, to inorganic phosphate. Monogastric animals (pigs and poultry) can only partially utilise this form of phosphorus. To increase the bioavailability of phosphorus for these types of animals, fungal phytase is added to the feed. This results in a decreased need to add inorganic phosphorus and a ...
Bacteria secreted enzyme mostly are cell associated and the only bacteria that produces extracellular phytases are of the genera Bacillus (Choi et al., 2001; Kerovou et al., 1998; Kim et al., 1998). Bacterial phytases are detected in many species like Bacillus, Pseudomonas, E.coli, Klebsiella, Lactobacillus species (Quan et al., 2001; Pandey et al., 2001; Kim et al., 1999, 1998; Griener et al.,1993; Shimuzu, 1992; Yoon et al.,1996). Bacterial phytases are generally produced by submerged fermentation at pH 7.0. Some bacterial phytases, especially those of the genera Bacillus and Enterobacter, exhibit pH optima in the range from 6.0 to 8.0 (Shimizu, 1992). Therefore, they would be more beneficial as feed additives for poultry as their pH optimum is close to the physiological pH of the poultry crop. The phytases of E. coli have been reported to be periplasmic enzymes (Greiner et al., 1993) and phytase activity in Selenomonas ruminantium, Bacillus spp. and Mitsuokella multiacidus was found to be ...

Phytate, an anti-nutrient, chelates essential minerals that are vital for human health. In the past few decades, research reports emphasize extensively on phytate degradation in animals. There is a growing need for finding alternate strategies of phytate utilization in human, as they are unable to produce phytase. At this juncture, probiotics can be utilized for phytase production to combat mineral deficiency in humans. The main focus of this review is on improving phosphate bioavailability by employing two approaches: supplementation of (1) fermented food products that contain probiotics and (2) recombinant phytase producing bacteria. In addition, several factors influencing phytase activity ...

The majority of feed ingredients used in poultry diets are derived from plant cereals such as soybean, corn, wheat, or barley. Anti-nutritional factors and indigestible components in plants can be a factor that can affect the quality of a formulated diet. The phytate in plant material is a nutritional obstacle for monogastric animals1. Some researchers have indicated that the supplementation of broiler feeds with phytase can alleviate the effects of anti-nutritional factors and improve bird performance2.. The use of exogenous phytase supplementation has been reported to improve the use of phytate phosphorus3. In addition to enzymes, the benefit of insoluble non-starch polysaccharides (iNSPs) in broiler diets has also been reported in many studies. Many of the benefits have been associated with improving gut health4 and gizzard function5 and increasing starch digestibility and growth performance in broilers and layers6.. In this context a new study was carried out to evaluate the effects of using ...
Bio Blend® consists of a synergistic consortium of targeted beneficial microorganisms, minerals, plants and animal by-products that are combined to produce a fermented feed grade product to supplement the animal diet. The production of quality meat and milk begins with healthy animals. Modern animal feeds are predominately composed of plant material, mainly cereals and vegetable proteins. Much of these ingredients cannot be fully digested and utilized, especially by monogastric animals. Enzymes increase the digestibility of these modern animal feeds, which improve feed to gain ratios for ruminants and monogastric animals alike.. Enzymes can provide more energy due to better utilization of nutrients which promotes healthy weight gain, enhances immune response, improves skin and coat condition, and increases and maintains vitality for ruminant and monogastric animals alike.. The balance of beneficial and potentially harmful bacterial in the animal gut is an important aspect in the overall health ...
Phosphate is essential for optimal growth of swine and poultry. Because pigs and poultry are unable to metabolize this nutrient directly from plant sources, phosphorus supplements are often added to animal feed. This increases the phosphorus content of manure, which when spread over fields tends to seep into the ground water and pollute lakes and streams with drastic environmental consequences.. A less common approach taken by some farmers has been to add the enzyme phytase directly to the feed, which releases the phosphorus compounds from plant matter. While eliminating the need for supplements, phytase-treated food is expensive to produce and the enzyme can lose its potency during storage. Cecil Forsberg, of the University of Guelph, in Ontario, and colleagues believe that engineering animals with the phytase gene incorporated into their genome overcomes these issues. Forsbergs team engineered mice that secrete the bacterial enzyme phytase in their saliva. The enzyme allows the animals to ...
There are many types of feed additives on the market today that perform a variety of specific functions. Certain additives promote optimal growth and others improve palatability. Phytase is a feed additive that breaks down phytates to promote the release of inorganic phosphorus bound in plant-based feed ingredients. Phytate is classified as an indigestible acid…
A process for the production of a modified phytase with a desired property improved over the property of the corresponding unmodified phytase is disclosed, as well as modified phytases, polynucleotides encoding modified phytases, and animal feed including modified phytases.
An experiment was conducted to investigate the effect of phytase transgenic corn (PTC) on intestinal microflora, and the fate of transgenic DNA and protein in the digesta and tissues of broilers. A total of 160 1-day-old Arbor Acres commercial male broilers were randomly assigned to 20 cages (8 chicks per cage) with 10 cages (replicates) for each treatment. Birds were fed with a diet containing either PTC (54.0% during 1-21 days and 61.0% during 22-42 days) or non-transgenic isogenic control corn (CC) for a duration of 42 days. There were no significant differences (P|0.05) between birds fed with the PTC diets and those fed with the CC diets in the quantities of aerobic bacteria, anaerobic bacteria, colibacillus and lactobacilli, or microbial diversities in the contents of ileum and cecum. Transgenic phyA2 DNA was not detected, but phyA2 protein was detected in the digesta of duodenum and jejunum of broilers fed with the PTC diets. Both transgenic phyA2 DNA and protein fragments were not found in the
I see that this was obtained from a pre-existing library that they made, but the relative paper (reference 36) is not yet available. So, we do not know what the number of clones in the library was, what was the insert size and what was the vector. These did not appear in the Results or in the Methods section. I also thought that they could have described, very briefly, how they screened the library for the activity in the E. coiicolonies.. Rebuttal:. The required information (number of clones of the library, vector, insert size and a brief description of the screening strategy) was added to the methods section. (Lines 387-393).. They then describe the make-up of the particular cloned insert and find many open reading frames. What seemed very odd was that there were predicted ORFs on both stands for nearly the whole insert. They do not make comments on this, though. I think that they should.. Rebuttal:. The corresponding explanation was added in the methods section (lines 397-400).. I also think ...
According to the latest research, up to 30% of the performance response seen in broilers following phytase superdosing may be due to the beneficial effects of the inositol released following complete phytate degradation.

Click here to view the video. Phytate breakdown products also anti-nutritive. Recent publications have shown that it is not just phytate that has anti-nutritive effects; the breakdown products of phytate - IP5, IP4 and IP3 - can also have an anti-nutritive effect in the animal. These lower phytate esters have been shown to correlate with poor digestion of protein; energy; and minerals, indicating that they have an anti-nutritive effect in the animal. The key point is that, with standard phytase dosing, we may be degrading one anti-nutrient and simply replacing it with another.. Despite this, confusion still exists in the market as to what superdosing is and how this should be defined. Many end-users have now adopted the practise of superdosing, which involves using higher phytase doses in feed to reduce the anti-nutritional effects of phytate (IP6) in pigs and poultry. This has proven to give additional animal performance benefits beyond standard phytase doses.. Ongoing research and customer ...
Gone are the days when phytase was only used to unlock phosphorus. Superdosing phytase - at a higher dosage than conventional dosing - has been shown to lead to so-called extra-phosphoric effects. The result is higher performance gains in pig production.

Elimination of a disulfide bridge in Aspergillus niger NRRL 3135 Phytase (PhyA) enhances heat tolerance and optimizes its temperature versus activity profile. Advances in Biological Chemistry. 2(4):372-378. Interpretive Summary: Today, much of the animal feed produced for swine, poultry and other animals with simple stomachs contain grains and other plant material rich in phytate. Phytate is common in plants and is high in phosphorus, which is an essential nutrient. However these animals lack an enzyme in their digestive tract, a phytase, that would allow them to break the phytate down and to access the phosphorus bound up in phytate. To overcome this problem, a phytase from a mold is produced and marketed as a feed additive. It allows the animals to use the phytin phosphorus and also as a bonus lowers the phosphorus levels in their manure to protect the environment. The enzyme has been widely accepted and ...

It consist of organs such as the mouth, oesophagus, the stomach, intestines, liver, etc., called the alimentary canal.. Farm animals show variation in the general structure and functions of their stomach. While cattle, sheep and goats have their stomach modified into four chambers, (polygastric animals or ruminants), domestic fowls, pigs, rabbits and even man have a simple stomach. These animals are called monogastric animals.. Digestion in Monogastric Animals e.g. pig and rabbit.. Mouth: Here, the food is chewed and masticated, mixed with saliva, rolled into a bolus and sent through the oesophagus to the stomach by peristaltic movement. During its stay in the mouth, the food reacts with an enzyme called ptyalin or salivary amylase which converts starch to maltose. Ptyalin works best in alkaline medium.. Oesophagus: Digestion in its real sense does not take place in the oesophagus. It merely acts as a passage. When food enters the oesophagus, its muscular walls will begin to contract and expand ...

Microorganisms that release plant-available phosphate from natural soil phosphate stores may serve as biological alternatives to costly and environmentally damaging phosphate fertilizers. To explore this possibility, we engineered a collection of root bacteria to release plant available orthophosphate from phytate, an abundant phosphate source in many soils. We identified 82 phylogenetically diverse phytase genes, refactored their sequences for optimal expression in Proteobacteria, then synthesized and engineered them into the genomes of three root-colonizing bacteria. Liquid culture assays revealed 41 engineered strains with high levels of phytate hydrolysis. Among these, we identified 12 strains across three bacterial hosts that confer a growth advantage on the model plant Arabidopsis thaliana when phytate is the sole phosphate source. These data demonstrate that DNA synthesis approaches can be used to generate plant-associated strains with novel phosphate solubilizing capabilities.Importance ...

Feed enzymes lead to better feed conversion by the animal, improved feed quality, and represent an active contribution to animal welfare. Feed enzymes help to break down anti-nutritional factors (fiber and phytate) that are present in many feed ingredients. They are used to increase the availability of starch, protein, amino acids, and minerals, such as phosphorus and calcium from feed ingredients. In addition, they can be used to supplement the enzymes produced by young animals where, because of an immature digestive system, enzyme production may be inadequate. Enzymes are proteins that are ultimately digested or excreted by the animal, leaving no residue in meat or eggs ...

A 2 × 2 × 3 factorial arrangement of treatments was used to investigate the effects of two levels of dietary crude protein (200 or 240 g kg-1) and two inclusion rates of phytase enzyme supplementation (with or without) on performance, jejunum morphology, and some hematological parameters of Japanese quails fed diets based on three graded levels of sesame (Sesamum indicum) meal (0, 120, and 240 g kg-1 of the diet). A total of 480 Japanese quail chicks were randomly allocated to 12 treatments with 4 replicates of 10 Japanese quails. The results showed that feed intake was decreased in quails fed diets containing 240 g kg-1 of sesame meal (P , 0.05). Diets with 120 and 240 g kg-1 inclusion rates of sesame meal improved feed conversion ratio (FCR) in Japanese quail (P , 0.05). Results indicated that the higher level of crude protein improved protein efficiency ratio (PER) and increased feed intake (P , 0.05).

Phosphate-solubilizing and phytate-mineralizing bacteria collectively termed as phosphobacteria provide a sustainable approach for managing P-deficiency in agricultural soils by supplying inexpensive phosphate to plants. A phosphobacterium Bacillus subtilis strain KPS-11 (Genbank accession no. KP006655) was isolated from potato (Solanum tuberosum L.) rhizosphere and characterized for potato plant growth promoting potential. The strain utilized both Ca-phosphate and Na-phytate in vitro and produced 6.48 μg mL-1 indole-3-acetic acid in tryptophan supplemented medium. P-solubilization after 240 h was 66.4 μg mL-1 alongwith the production of 19.3 μg mL-1 gluconic acid and 5.3 μg mL-1 malic acid. The extracellular phytase activity was higher (4.3 × 10-10 kat mg-1 protein) than the cell-associated phytase activity (1.6 × 10-10 kat mg-1 protein). B. subtilis strain KPS-11 utilized 40 carbon sources and showed resistance against 20 chemicals in GENIII micro-plate system demonstrating its metabolic
Abstract. Four purified phytases isolated from Aspergillus niger and Escherichia coli were characterized biochemically and in terms of their adsorption to soils belonging to the Mollisol order. Three different organic P substrates were used to measure enzyme activity in a wide range of pH (2.3 to 9) and temperatures (−10° to 70 °C): p-nitrophenyl-phosphate, glyceraldehyde-3-phosphate and phytic acid. Phytases from A. niger showed a higher capacity to release P (36 to 50 % of P contained in the substrates, 44 to 62 μg P), than phytases from E. coli (24 to 36 %, 20 to 44 μg P). The amount of P released from organic P substrates by A. niger phytases followed the following range: p-nitrophenyl-phosphate > glyceraldehyde-3-phosphate > phytic acid whereas in E. coli phytases the order was p-nitrophenyl-phosphate/glyceraldehyde-3-phosphate > phytic acid. All phytases were active throughout the pH and temperature ranges for optimum crop production. The proportion of phytases found in the solid ...

Phosphorus is one of the major constituents of which are involved in metabolic processes, nucleic acid and cell membranes biosynthesis as well as in the regulation of a large number of enzymes. Phytate (myo-inositol hexakisphosphate 3-phosphorilase) is the main storage form of phosphorus in various crops (cereals, legumes, and oilseed crops) and its accumulation in natural ecosystems could reduce the availability of various metal ions such as Fe, Zn, Mg or Ca, and could cause environmental pollution effects. Phytases are enzymes that catalyze the hydrolytic phosphate cleavage of phytic acid to lour inositol phosphate esters and inorganic phosphate. In the case of monogastric animals which do not have microbial phytases in their digestive system, the formation of insoluble metal cation-phytate complexes at physiological pH values is regarded as the major reason for poor mineral availability, because these complexes are essentially nonabsorbable from the gastrointestinal tract. However, phosphorus ...

The use of low protein and a new phytase enzyme were studied in swine diets, as nutritional strategies to improve the efficiency in the use of nitrogen and phosphorus, and also to reduce NH3 production and odor offensiveness from pig production, while producing environmentally friendly manure. The effect of reducing dietary crude protein (CP) in growing pigs was evaluated in two independent experiments, using either an adequate or a reduced CP level (19 or 14%). The first study measured the amount of N loss as aerial NH3 and odor offensiveness in the air from growing pigs confined in dynamic airflow chambers, and the second study evaluated the same diets using N balance techniques. Reducing dietary CP did not affect (P > 0.05) growth performance, but decreased slurry pH (P < 0.09) from 6.71 to 6.21 +/- 0.186. Reducing CP decreased (P < 0.001) urinary N excretion by 56% and total N excretion by 41%. Overall, for every one percentage unit reduction in dietary CP (combined with AA supplementation) ...

Vitamin and mineral deficiency is a serious health concern that affects a vast amount of the worlds population. Surprisingly, this deficiency is not always due to a lack of nutrients in the diet but rather due to the low bioavailability, and thus poor absorption, of those nutrients. Specifically, according to the World Health Organization iron deficiency affects over 30% of the worlds population and affects more people than any other condition in the world. Iron deficiency can lead to anemia, general ill-health, and premature death. Iron and other nutrients are not available in the food we eat due to molecules known as chelators. Chelators bind to nutrients rendering them unavailable for the body to use. Our project focuses on breaking down the strongest and most prevalent chelator of iron in foods: phytic acid (phytate). Phytic acid is naturally broken down by enzymes known as phytases. We aim to build a system to directly deliver phytase to the digestive system in order to increase the ...
To study the character of P fractions and acid phosphatase in leaf, we conducted a pot experiment of super-low P (25 mg·kg-1 soil), low P (50 mg·kg-1 soil) and normal P (75 mg·kg-1 soil) in P-efficient barley (DH110, DH147) and P-inefficient barley (DH49). Inorganic P concentration was reduced significantly by low P stress, except for insoluble phosphate, in leaves of barley. The nucleic P concentration in upper leaves was higher in P-efficient than P-inefficient barley, but the nucleic P concentration in bottom leaves was lower; only 18.4% to 91.4% of that in P-inefficient barley. The ester P concentration and distribution ratio in bottom leaves was less in P-efficient than P-inefficient barley. However, the ester P concentration was decreased significantly only in P-inefficient barley and was significantly lower than in P-efficient barley.

Adalimumab was the first fully human monoclonal antibody approved by the US Food and Drug Administration (FDA).[37] It was derived from phage display.[38][37] Adalimumab was discovered as a result of a collaboration between BASF Bioresearch Corporation and Cambridge Antibody Technology, U.K., itself a collaboration of the government-funded Medical Research Council and three academics, which began in 1993.[39][40][37] Initially named D2E7,[41] it was then further manufactured at BASF Bioresearch Corporation, developed by BASF Knoll (BASF Pharma), and ultimately manufactured and marketed by Abbott Laboratories after Abbotts acquisition of BASF Pharma. On 1 January 2013, Abbott split into two companies, one retaining the Abbott name and the other named AbbVie.[42] As a result, AbbVie took over development and marketing of Humira.[43][44] The brand name Humira stands for human monoclonal antibody in rheumatoid arthritis, and was named by one of Abbotts employees, Richard J. Karwoski, who was ...

Enhancing feed value. Due to volatility in raw material prices, the focus of farmers is now shifted on innovative formulations that help birds to perform on less digestible feed ingredients. Use of EPPA helps to increase this flexibility in formulating cheaper diets without negative impact on performance. This is due to a novel and relevant combination of xylanase, amylase, cellulase and phytase, which are able to release extra energy from less digestible substrates. As higher levels of cheaper alternative raw material are added to poultry diets, the use of EPPA offers the means of reducing the problem of gut viscosity which is usually linked to the significant amount of non-starch polysacccharides (NSP). Specific enzymes in EPPA combined with optimum dosage help to minimize the cost effectiveness of the feed.. Higher net profits. The poultry industry world over and particularly in India is passing through a phase of uncertainity with cost components reaching critical limits. Inclusion of EPPA ...

  • Phytic acid, the major storage form of phosphorus in plant seeds is degraded by the phytases to yield inositol and free phosphate, contributing thereby to the improved bioavailability of phytate phosphorus and essential minerals in plant foods and simultaneous reduction in phosphorus pollution of the terrestrial and aquatic ecosystems. (
  • BPPs are the most widely found phytase superfamily in the environment and they are thought to have a major role in phytate-phosphorus cycling in soil and water. (
  • The effect of dietary phosphorus level and phytase supplementation on growth performance, bone-breaking strength, and litter phosphorus concentration in broilers. (
  • The 2 diets consisted of an industry diet (IND) and a low phosphorus + 600 U of phytase/kg (LP) diet. (
  • Through the hydrolysis reaction, phytase liberates phosphorus so that the body can use it. (
  • While dietary phytic acid in plant foods does have some positive effects, such as deterring kidney stones and preventing heart disease and diabetes, phytase is an enzyme that plays an important role by breaking down additional phytic acid and freeing up the phosphorus for use in the body. (
  • Phytase breaks down bound, unusable forms of phosphorus so your body can use and absorb it. (
  • An animal trial done at Auburn University found phytase not only increased the availability of phosphorus, but also led to better body weight, digestive efficiency, and overall bone strength in lab animals. (
  • Phytase supplementation in broiler diets is a common practice to improve phosphorus (P) availability and to reduce P loss by excretion. (
  • Phytase is used primarily for the feeding of simple hermit animals in order to increase the usability of amino acids, minerals, phosphorus and energy. (
  • His symptoms could be ascribed to hypersensitivity pneumonitis due to contact with phytase, an enzyme added to cattle feed to strengthen bone and diminish phosphorus excretion. (
  • Phosphorus in the soil solution exists as insoluble inorganic phosphorus and insoluble organic phosphorus [ 6 ]. (
  • Consequently, deficiency of phosphorus severely restricts the growth and yield of crops [ 6 ]. (
  • The phosphorus level in the soil is about 0.05% [ 2 , 6 ]. (
  • This study aimed to distinguish between the single and interactive effects of phosphorus (P), calcium (Ca), and phytase on products of phytate degradation, including the disappearance of myo-inositol (MI), P, Ca, and amino acids (AA) in different segments of the digestive tract in broiler chickens. (
  • Interactive effects of phosphorus, calcium, and phytase supplements on products of phytate. (
  • 3-Phytase A enhanced phosphorus retention and metabolic balances in rats and exerted detrimental effects on metabolic parameters of calcium. (
  • The effect was stimulated by a subsequent addition of phytase B. The opposite was true for 6-phytase A that repressed phosphorus and preserved calcium metabolic balances in rats. (
  • The purpose of the current investigation was to evaluate the extent of phytate breakdown in breads supplemented with different phytases and to learn changes in in vitro nutrient digestibility and in phosphorus and calcium metabolic balances in rats. (
  • The bioavailability of phytate phosphorus can be increased by supplementation of the diet with the phytase enzyme. (
  • Due to the inability of poultry to produce own phytase the availability of phosphorus, calcium, protein and other nutrients is limited. (
  • Since monogastric animals like poultry and pigs have very low or no phytase activities in their digestive tracts, inorganic phosphorus has to be added to the feed in order to meet the phosphorus requirements of these animals. (
  • A total of 720 straight-run Heritage 56 M × fast feathering Cobb 500F broiler chickens was fed from 11 to 13 d of age to determine the impacts of dietary calcium (Ca), phytate phosphorus (PP), and phytase concentrations on inositol phosphate (IP3-6) profile in different digestive tract (GI) segments. (
  • 2 This fact sheet will briefly explain the different ways that P can be expressed, how to assign a phosphorus (P) value to an ingredient, and the effects of naturally occurring phytase and diet form on P digestibility. (
  • Historically, phytases have been used in the monogastric feed sector as an enzyme to break down phytate, releasing phosphorus (P) to the animal that was previously unavailable. (
  • BASF said its new generation phytase helps pigs and poultry utilize phosphorus and key nutrients more efficiently, bringing a wide range of benefits to local farmers and the animal feed industry. (
  • Phosphorus and inositol in phytate form is not bioavailable to monogastric animals like pigs and poultry as the animals lack the digestive phytase enzyme to remove phosphate from the inositol in the phytate molecule. (
  • It is said the bioavailability of phytate phosphorus can be increased through the supplementation of pig and poultry feed with a phytase enzyme. (
  • Thus, phytases supplied in animal feeds not only improve phytate utilization in monogastric ani- mals, but also alleviate phytate phosphorus pollution [6]. (
  • The experimental design was completely randomized design with a 3H2 factorial arrangement with three levels (0, 2 and 4%) of citric acid and two levels (0.0 and 300 FTU kg -1 ) of microbial phytase in low available phosphorus diets with 6 treatments, 4 replicates and 8 hens in each replicate. (
  • A synergistic effect between Citric Acid (CA) and Microbial Phytase (MP) in improving phytate Phosphorus (P) utilization have been reported in broiler previously. (
  • Phytase is used as an animal feed additive that degrades phytic acid and reduces feeding costs and pollution caused by fecal excretion of phosphorus. (
  • Phytases are enzymes that dephosphorylate the phytate (myo-inositol hexakisinositolphosphate to myo inositol) and release inorganic phosphate plus free inositol, makes phosphorus available for absorption. (
  • This paper summarizes the information on natural and genetically modified sources of phytases along with main focus on their relative productivity and their associated role towards removal of phosphorus from environment. (
  • The 3-phytases begins by removing the phosphate in the carbon 3rd position and yields 1,2,4,5,6 pentakisphosphate, while the 6-phytases in the carbon 6th position yields 1,2,3,4,5 pentakisphosphate as the first product along with Pi (inorganic phosphorus). (
  • The main reason for using an exogenous added phytase in feed is to liberate phosphorus (P), bound as phytate, in raw materials. (
  • The effect of dietary phosphorus and calcium level, phytase supplementation, and ileal infusion of pectin on the chemical composition and carbohydrase activity of fecal bacteria and the level of microbial metabolites in the gastrointestinal tract of pigs. (
  • Abstract Background: Phytases (myo-inositol hexakisphosphate phosphohydrolases) catalyse the release of phosphate from phytic acid myo-inositol hexakisphosphate (InsP6) and is the major phosphorus-storage form in plants, including most cereals and legumes. (
  • The act of phytase also donates towards plummeting the contamination in diverse superficial and ground water produced by the phytate and phosphorus run-off from dung in concentrated livestock districts (Hayes, et al. (
  • This study investigated the effect of microbial phytase supplementation on growth performance, tibia ash, plasma parameters, apparent ileal digestibility (AID) of amino acid (AA) and apparent digestibility of nutrients in Youxian Sheldrakes fed with low-phosphorus (P) corn-soybean diets. (
  • The subject products consist of two enzyme preparations, each containing a genetically modified form of the enzyme, 6-phytase, which is produced in yeast using recombinant DNA techniques. (
  • In enzymology, a 5-phytase (EC is an enzyme that catalyzes the chemical reaction myo-inositol hexakisphosphate + H2O ⇌ {\displaystyle \rightleftharpoons } 1L-myo-inositol 1,2,3,4,6-pentakisphosphate + phosphate myo-Inositol hexakisphosphate is also known as phytic acid. (
  • Phytase is a phosphatase enzyme that catalyzes, or kickstarts, the hydrolysis of phytic acid, also known as phytate. (
  • 2006 ). These problems can be effectively addressed if the straw-derived feed diets are supplemented with phytase, an enzyme that degrades phytic acid. (
  • To defined the substrate specificity of the phytase, the hydrolysis of several phosphorylated compounds by the purified enzyme was studied and sodium phytate showed high specificity. (
  • The feed additive contains a unique combination of 19 compatible and naturally occuring enzymes, produced by the non-GM organism Penicillium funiculosum, plus a 20th enzyme, a 6-phytase. (
  • This synergetic NSP enzyme and phytase combination offers maximum benefits by reducing animal fat or vegetable oil up to 10Kg/ Ton of feed and mineral phosphate up to 10Kg/tonnes of feed. (
  • Present investigation involves studies on the effect of carbon and nitrogen sources, temperature and pH on the production of phytase enzyme by Aspergillus niger in submerged fermentation. (
  • The optimum temperature for phytase activity was found to be 50°C. The enzyme retained over 75% of its activity over a temperature range of 30 to 80°C. The highest phytase activity was observed at pH 4.5 and a decline of enzyme activity was observed on both sides of pH optimum. (
  • These properties suggest that this phytase is a suitable enzyme for the hydrolysis of phytic acid and phytates in food and feed processing industries. (
  • 4. Rao, D.E., Rao, K.V. and Reddy, V.D. (2008) Cloning and expression of Bacillus phytase gene (phy) in Escherichia coli and recovery of active enzyme from the inclusion bodies. (
  • The digestive enzyme phytase digestive enzymes in the gastrointestinal tracts of mono- can hydrolyze phytic acid or phytate into lower inositol gastric animals (swine, poultry, fish, etc.), phytate cannot phosphates [5]. (
  • So from last two decades, phytase enzyme has attracted scientists and entrepreneurs in the areas of nutrition, environmental protection and biotechnologists. (
  • The International Union of Biochemists categorizes the phytase enzyme into two classes namely 3-phytase and 6-phytase based on where dephosphorylation initiated on phytate molecule. (
  • Two experiments evaluated the apparent metabolisable energy (AME) values for cereal grains fed with and without a blend of xylanase and phytase enzyme products to broiler chickens. (
  • All grains were fed with and without a blend of xylanase and phytase enzyme products. (
  • All grains were fed with and without a blend of xylanase (Porzyme 93010 at 50g per tonne for wheat, barley and triticale, or Rovabio Excel at 200g per tonne for sorghum) and phytase (Phyzyme TPT at 50g per tonne) enzyme products. (
  • To determine whether this phytase could be expressed in plants as a functional enzyme, we introduced the phytase gene from A. fumigatus (fphyA) in tobacco (Nicotiana tabacum L. cv. (
  • The above results showed that the thermostable A. fumigatus phytase could be expressed in tobacco as a functional enzyme and thus has the potential of overexpressing it in other crop plants also. (
  • These enzymes fit to a singular aspect of class concerning the phosphomonoesterases (myo-inositol hexakisphosphate 3-phosphorylase, myo-inositol hexakisphosphate 6-phosphorylase, EC , and are accomplished of introducing the main release of phosphate from phytate [myo-inositol hexakisphosphate], which is measured the main storage procedure of phosphate in the aspects of enzyme activity (De Angelis, 2003). (
  • Phytases have also been found in wheat bran, plant seeds, animal intestines and in microorganisms [Howsen and Davis, Enzyme Microb. (
  • Glucose 6-phosphatase ( EC , G6Pase) is an enzyme that hydrolyzes glucose 6-phosphate , resulting in the creation of a phosphate group and free glucose. (
