A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
An 11-kDa protein associated with the outer membrane of many cells including lymphocytes. It is the small subunit of the MHC class I molecule. Association with beta 2-microglobulin is generally required for the transport of class I heavy chains from the endoplasmic reticulum to the cell surface. Beta 2-microglobulin is present in small amounts in serum, csf, and urine of normal people, and to a much greater degree in the urine and plasma of patients with tubular proteinemia, renal failure, or kidney transplants.
INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.
A specific decapeptide obtained from the skin of Hila caerulea, an Australian amphibian. Caerulein is similar in action and composition to CHOLECYSTOKININ. It stimulates gastric, biliary, and pancreatic secretion; and certain smooth muscle. It is used in paralytic ileus and as diagnostic aid in pancreatic malfunction.
Receptors, Adrenergic, beta
An enzyme that hydrolyzes 1,6-alpha-glucosidic branch linkages in glycogen, amylopectin, and their beta-limit dextrins. It is distinguished from pullulanase (EC 188.8.131.52) by its inability to attack pullulan and by the feeble action of alpha-limit dextrins. It is distinguished from amylopectin 6-glucanohydrolase (EC 184.108.40.206) by its action on glycogen. With EC 220.127.116.11, it produces the activity called "debranching enzyme". EC 18.104.22.168.
A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety.
Transforming Growth Factor beta
A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.
This intrgrin is a key component of HEMIDESMOSOMES and is required for their formation and maintenance in epithelial cells. Integrin alpha6beta4 is also found on thymocytes, fibroblasts, and Schwann cells, where it functions as a laminin receptor (RECEPTORS, LAMININ) and is involved in wound healing, cell migration, and tumor invasiveness.
Integrin beta Chains
Integrin beta chains combine with integrin alpha chains to form heterodimeric cell surface receptors. Integrins have traditionally been classified into functional groups based on the identity of one of three beta chains present in the heterodimer. The beta chain is necessary and sufficient for integrin-dependent signaling. Its short cytoplasmic tail contains sequences critical for inside-out signaling.
beta 2-Glycoprotein I
A 44-kDa highly glycosylated plasma protein that binds phospholipids including CARDIOLIPIN; APOLIPOPROTEIN E RECEPTOR; membrane phospholipids, and other anionic phospholipid-containing moieties. It plays a role in coagulation and apoptotic processes. Formerly known as apolipoprotein H, it is an autoantigen in patients with ANTIPHOSPHOLIPID ANTIBODIES.
Integrin alpha4beta1 is a FIBRONECTIN and VCAM-1 receptor present on LYMPHOCYTES; MONOCYTES; EOSINOPHILS; NK CELLS and thymocytes. It is involved in both cell-cell and cell- EXTRACELLULAR MATRIX adhesion and plays a role in INFLAMMATION, hematopoietic cell homing and immune function, and has been implicated in skeletal MYOGENESIS; NEURAL CREST migration and proliferation, lymphocyte maturation and morphogenesis of the PLACENTA and HEART.
The major component (about 80%) of the PANCREAS composed of acinar functional units of tubular and spherical cells. The acinar cells synthesize and secrete several digestive enzymes such as TRYPSINOGEN; LIPASE; AMYLASE; and RIBONUCLEASE. Secretion from the exocrine pancreas drains into the pancreatic ductal system and empties into the DUODENUM.
An integrin found on fibroblasts, platelets, endothelial and epithelial cells, and lymphocytes where it functions as a receptor for COLLAGEN and LAMININ. Although originally referred to as the collagen receptor, it is one of several receptors for collagen. Ligand binding to integrin alpha2beta1 triggers a cascade of intracellular signaling, including activation of p38 MAP kinase.
Receptors, Adrenergic, beta-2
A subclass of beta-adrenergic receptors (RECEPTORS, ADRENERGIC, BETA). The adrenergic beta-2 receptors are more sensitive to EPINEPHRINE than to NOREPINEPHRINE and have a high affinity for the agonist TERBUTALINE. They are widespread, with clinically important roles in SKELETAL MUSCLE; LIVER; and vascular, bronchial, gastrointestinal, and genitourinary SMOOTH MUSCLE.
Salivary Proteins and Peptides
The amount of a substance secreted by cells or by a specific organ or organism over a given period of time; usually applies to those substances which are formed by glandular tissues and are released by them into biological fluids, e.g., secretory rate of corticosteroids by the adrenal cortex, secretory rate of gastric acid by the gastric mucosa.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
A family of transmembrane glycoproteins (MEMBRANE GLYCOPROTEINS) consisting of noncovalent heterodimers. They interact with a wide variety of ligands including EXTRACELLULAR MATRIX PROTEINS; COMPLEMENT, and other cells, while their intracellular domains interact with the CYTOSKELETON. The integrins consist of at least three identified families: the cytoadhesin receptors(RECEPTORS, CYTOADHESIN), the leukocyte adhesion receptors (RECEPTORS, LEUKOCYTE ADHESION), and the VERY LATE ANTIGEN RECEPTORS. Each family contains a common beta-subunit (INTEGRIN BETA CHAINS) combined with one or more distinct alpha-subunits (INTEGRIN ALPHA CHAINS). These receptors participate in cell-matrix and cell-cell adhesion in many physiologically important processes, including embryological development; HEMOSTASIS; THROMBOSIS; WOUND HEALING; immune and nonimmune defense mechanisms; and oncogenic transformation.
A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.
Integrin beta-1 chains which are expressed as heterodimers that are noncovalently associated with specific alpha-chains of the CD49 family (CD49a-f). CD29 is expressed on resting and activated leukocytes and is a marker for all of the very late activation antigens on cells. (from: Barclay et al., The Leukocyte Antigen FactsBook, 1993, p164)
A cell surface receptor mediating cell adhesion to the EXTRACELLULAR MATRIX and to other cells via binding to LAMININ. It is involved in cell migration, embryonic development, leukocyte activation and tumor cell invasiveness. Integrin alpha6beta1 is the major laminin receptor on PLATELETS; LEUKOCYTES; and many EPITHELIAL CELLS, and ligand binding may activate a number of signal transduction pathways. Alternative splicing of the cytoplasmic domain of the alpha6 subunit (INTEGRIN ALPHA6) results in the formation of A and B isoforms of the heterodimer, which are expressed in a tissue-specific manner.
Receptors, Adrenergic, beta-1
A subclass of beta-adrenergic receptors (RECEPTORS, ADRENERGIC, BETA). The adrenergic beta-1 receptors are equally sensitive to EPINEPHRINE and NOREPINEPHRINE and bind the agonist DOBUTAMINE and the antagonist METOPROLOL with high affinity. They are found in the HEART, juxtaglomerular cells, and in the central and peripheral nervous systems.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Integrin alpha1beta1 functions as a receptor for LAMININ and COLLAGEN. It is widely expressed during development, but in the adult is the predominant laminin receptor (RECEPTORS, LAMININ) in mature SMOOTH MUSCLE CELLS, where it is important for maintenance of the differentiated phenotype of these cells. Integrin alpha1beta1 is also found in LYMPHOCYTES and microvascular endothelial cells, and may play a role in angiogenesis. In SCHWANN CELLS and neural crest cells, it is involved in cell migration. Integrin alpha1beta1 is also known as VLA-1 and CD49a-CD29.
Glycogen Synthase Kinase 3
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Estrogen Receptor beta
Clinical Enzyme Tests
Transforming Growth Factor beta1
A subtype of transforming growth factor beta that is synthesized by a wide variety of cells. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta 1 and TGF-beta1 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor. Defects in the gene that encodes TGF-beta1 are the cause of CAMURATI-ENGELMANN SYNDROME.
Receptors, Adrenergic, beta-3
Crystal structure of beta-amylase from Bacillus cereus var. mycoides at 2.2 A resolution. (1/94)The crystal structure of beta-amylase from Bacillus cereus var. mycoides was determined by the multiple isomorphous replacement method. The structure was refined to a final R-factor of 0.186 for 102,807 independent reflections with F/sigma(F) > or = 2.0 at 2.2 A resolution with root-mean-square deviations from ideality in bond lengths, and bond angles of 0.014 A and 3.00 degrees, respectively. The asymmetric unit comprises four molecules exhibiting a dimer-of-dimers structure. The enzyme, however, acts as a monomer in solution. The beta-amylase molecule folds into three domains; the first one is the N-terminal catalytic domain with a (beta/alpha)8 barrel, the second one is the excursion part from the first one, and the third one is the C-terminal domain with two almost anti-parallel beta-sheets. The active site cleft, including two putative catalytic residues (Glu172 and Glu367), is located on the carboxyl side of the central beta-sheet in the (beta/alpha)8 barrel, as in most amylases. The active site structure of the enzyme resembles that of soybean beta-amylase with slight differences. One calcium ion is bound per molecule far from the active site. The C-terminal domain has a fold similar to the raw starch binding domains of cyclodextrin glycosyltransferase and glucoamylase. (+info)
The evolution of starch-binding domain. (2/94)Amylolytic enzymes belonging to three distinct families of glycosidases (13, 14, 15) contain the starch-binding domain (SBD) positioned almost exclusively at the C-terminus. Detailed analysis of all available SBD sequences from 43 different amylases revealed its independent evolutionary behaviour with regard to the catalytic domains. In the evolutionary tree based on sequence alignment of the SBDs, taxonomy is respected so that fungi and actinomycetes form their own separate parts surrounded by bacteria that are also clustered according to taxonomy. The only known N-terminal SBD from Rhizopus oryzae glucoamylase is on the longest branch separated from all C-terminal SBDs. The 3-dimensional (3-D) structures of fungal glucoamylase and bacterial CGTase SBDs are compared and used to discuss the interesting SBD evolution. (+info)
Prediction of protein cleavage sites by the barley cysteine endoproteases EP-A and EP-B based on the kinetics of synthetic peptide hydrolysis. (3/94)Hordeins, the natural substrates of barley (Hordeum vulgare) cysteine endoproteases (EPs), were isolated as protein bodies and degraded by purified EP-B from green barley malt. Cleavage specificity was determined by synthesizing internally quenched, fluorogenic tetrapeptide substrates of the general formula 2-aminobenzoyl-P(2)-P(1)-P(1)'-P(2)' 1-tyrosine(NO(2))-aspartate. The barley EPs preferred neutral amino acids with large aliphatic and nonpolar (leucine, valine, isoleucine, and methionine) or aromatic (phenylalanine, tyrosine, and tryptophan) side chains at P(2), and showed less specificity at P(1), although asparagine, aspartate, valine, and isoleucine were particularly unfavorable. Peptides with proline at P(1) or P(1)' were extremely poor substrates. Cleavage sites with EP-A and EP-B preferred substrate sequences are found in hordeins, their natural substrates. The substrate specificity of EP-B with synthetic peptides was used successfully to predict the cleavage sites in the C-terminal extension of barley beta-amylase. When all of the primary cleavage sites in C hordein, which occur mainly in the N- and C-terminal domains, were removed by site-directed mutagenesis, the resulting protein was degraded 112 times more slowly than wild-type C hordein. We suggest that removal of the C hordein terminal domains is necessary for unfolding of the beta-reverse turn helix of the central repeat domain, which then becomes more susceptible to proteolytic attack by EP-B.

Water stress enhances beta-amylase activity in cucumber cotyledons. (4/94)Cotyledons detached from 4-d-old cucumber (Cucumis sativus L.) seedlings were subjected to water stress (air-drying or PEG-treatment) to examine the effects of the stress on carbohydrate metabolism. Amylolytic activity in the cotyledon was increased about 6-fold by water stress within 1 d. The substrate specificity and the action pattern indicated that beta-amylase is responsible for the activity. Activities of azocaseinase, malate dehydrogenase and triose-phosphate isomerase were not affected by water stress, indicating that the effect of the stress on beta-amylase is rather specific. Cycloheximide-treatment strongly reduced the enhancement of beta-amylase activity. The hypocotyl of cucumber seedlings also exhibited an increase in the enzyme activity when subjected to water stress. The major free sugars in cucumber cotyledons were glucose, fructose, maltose, and sucrose; sucrose being the most abundant. Sucrose content in excised, unstressed cotyledons increased markedly during the incubation. Changes in other free sugars were small compared with that of sucrose. Starch also accumulated in unstressed cotyledons. In stressed cotyledons more sucrose and less starch accumulated than in unstressed ones. Such results were discussed in relation to the enhancement of beta-amylase activity. (+info)
Polymorphism in rice amylases at an early stage of seed germination. (5/94)A polymorphism in rice amylases at an early stage of seed germination is analyzed by zymogram. In non-glutinous cultivars of rice, alpha-amylase isozymes are mainly confirmed in germinating seeds. However, in glutinous cultivars, beta-amylase isozymes, which are not confirmed in nonglutinous cultivars, make up the major part of the total amylase activity and the expression of alpha-amylases are repressed. (+info)
Molecular mimicry of substrate oxygen atoms by water molecules in the beta-amylase active site. (6/94)Soybean beta-amylase (EC 22.214.171.124) has been crystallized both free and complexed with a variety of ligands. Four water molecules in the free-enzyme catalytic cleft form a multihydrogen-bond network with eight strategic residues involved in enzyme-ligand hydrogen bonds. We show here that the positions of these four water molecules are coincident with the positions of four potential oxygen atoms of the ligands within the complex. Some of these waters are displaced from the active site when the ligands bind to the enzyme. How many are displaced depends on the shape of the ligand. This means that when one of the four positions is not occupied by a ligand oxygen atom, the corresponding water remains. We studied the functional/structural role of these four waters and conclude that their presence means that the conformation of the eight side chains is fixed in all situations (free or complexed enzyme) and preserved from unwanted or forbidden conformational changes that could hamper the catalytic mechanism. The water structure at the active pocket of beta-amylase is therefore essential for providing the ligand recognition process with plasticity. It does not affect the protein active-site geometry and preserves the overall hydrogen-bonding network, irrespective of which ligand is bound to the enzyme. We also investigated whether other enzymes showed a similar role for water. Finally, we discuss the potential use of these results for predicting whether water molecules can mimic ligand atoms in the active center. (+info)
Activities of starch hydrolytic enzymes and sucrose-phosphate synthase in the stems of rice subjected to water stress during grain filling. (7/94)To understand the effect of water stress on the remobilization of prestored carbon reserves, the changes in the activities of starch hydrolytic enzymes and sucrose-phosphate synthase (SPS) in the stems of rice (Oryza sativa L.) during grain filling were investigated. Two rice cultivars, showing high lodging-resistance and slow remobilization, were grown in the field and subjected to well-watered (WW, psi(soil)=0) and water-stressed (WS, psi(soil)=-0.05 MPa) treatments 9 d after anthesis (DAA) till maturity. Leaf water potentials of both cultivars markedly decreased during the day as a result of WS treatment, but completely recovered by early morning. WS treatment accelerated the reduction of starch in the stems, promoted the reallocation of prefixed (14)C from the stems to grains, shortened the grain filling period, and increased the grain filling rate. More soluble sugars including sucrose were accumulated in the stems under WS than under WW treatments. Both alpha- and beta-amylase activities were enhanced by the WS, with the former enhanced more than the latter, and were significantly correlated with the concentrations of soluble sugars in the stems. The other two possible starch-breaking enzymes, alpha-glucosidase and starch phosphorylase, showed no significant differences in the activities between the WW and WS treatments. Water stress also increased the SPS activity that is responsible for sucrose production. Both V(limit) and V(max), the activities of the enzyme at limiting and saturating substrate concentrations, were enhanced and the activation state (V(limit)/V(max)) was also increased as a result of the more significant enhancement of V(limit). The enhanced SPS activity was closely correlated with an increase of sucrose accumulation in the stems. The results suggest that the fast hydrolysis of starch and increased carbon remobilization were attributed to the enhanced alpha-amylase activity and the high activation state of SPS when the rice was subjected to water stress.

Purification, characterization, immunolocalization and structural analysis of the abundant cytoplasmic beta-amylase from Calystegia sepium (hedge bindweed) rhizomes. (8/94)An abundant catalytically active beta-amylase (EC 126.96.36.199) was isolated from resting rhizomes of hedge bindweed (Calystegia sepium). Biochemical analysis of the purified protein, molecular modeling, and cloning of the corresponding gene indicated that this enzyme resembles previously characterized plant beta-amylases with regard to its amino-acid sequence, molecular structure and catalytic activities. Immunolocalization demonstrated that the beta-amylase is exclusively located in the cytoplasm. It is suggested that the hedge bindweed rhizome beta-amylase is a cytoplasmic vegetative storage protein. (+info)
Development of intestinal microflora and occurrence of diarrhoea in sucking foals: effects of Bacillus cereus var. toyoi...
The present study was performed on a studfarm under typical field conditions. To minimize effects related to husbandry, feeding, and season, our study took place at one thoroughbred farm, within one foaling period from February to May. According to Lahrssen and Zentek  such a study design is important when working with a limited number of animals. Probiotic dosing and treatment period were in accordance with studies by Jeroch et al. , Jadamus et al. , and Vilà et al. .. Unfortunately some foals were treated with antibiotics during a severe period of illness which may have an impact on the subsequent microbial profile in faeces.. Bacterial microflora in faeces was used as an indication of the effects of B. cereus var. toyoi on the intestinal health of foals. Although faeces might have some limitations for describing the gut ecosystem, by comparing microflora and the digestion process in the colon with faeces in fistulated horses Julliand and Goachet  showed that the faecal ...

Chemical and Morphological Studies of Bacterial Spore Formation | Journal of Cell Biology | Rockefeller University Press
The purine analogue, 8-azaguanine, was added to cultures of the parasporal crystal-forming organism Bacillus cereus var. alesti at different times during growth and synchronous sporulation. The effect of its incorporation has been studied with particular reference to cell growth, nucleic acid composition, cytology, and the synthesis of the spore and crystal protein. Additions of the analogue during any stage of growth prevented further cell proliferation and all spore and crystal formation. Since both nucleic acids continued to be formed, cells of an increased size developed, containing large masses of chromatin in the form of condensed balls or axial cords. Lipid-containing inclusions also appeared following these additions and were usually aggregated at the centre or poles of the cells. The analogue could be isolated as the ribonucleotide from both the acid soluble and RNA fractions of these inhibited cells. Additions of the analogue following commencement of sporulation did not prevent either ...

The Minimal Nutritional Requirements of Some Species in the Genus Bacillus | Microbiology Society
Summary: The characteristic nutritional patterns were determined for seven species or varieties of the genus Bacillus. Six strains of Bacillus cereus var. anthracis grew in a complex but defined amino acid medium + thiamine. Three strains of the insect pathogen B. cereus var. thuringiensis had the same nutritional pattern as the parent species B. cereus and grew in a seven amino acid medium. Of twenty strains of B. firmus, ten grew on the seven amino acid medium + biotin while the growth of five other strains was markedly affected by the addition of thiamine. Two of the remaining five strains required thiamine on first isolation, but soon dispensed with it on subculture, while the other three strains continued to require thiamine. Six strains of B. lentus grew in the seven amino acid medium + biotin + thiamine + urea. When the seven amino acid medium was replaced by the complex amino acid medium three of these strains of B. lentus grew without the addition of urea, and the remaining three strains

The experimental investigation of microorganisms capable of producing hydrogen for subsequent fuel cell use is described. The microorganisms Clostridium welchii, Aeromonas hydrophila and Bacillus polymyxa were screened using various substrates. Rate studies with E. coli on maltose and glucose and Pseudomonas sp. (G4A) on formate and glucose were conducted. The manner in which hydrogen is produced demonstrates the desirability of following the course of reaction continually. Full factorial studies, with three factors at two levels, were conducted with several organism-substrate systems. Along with results obtained from previous factional factorial experiments, further definition of the criteria for maximizing hydrogen production has been established. Scale-up studies with E. coli-glucose show that the factors governing laboratory scale studies are applicable to large volume fermenters. (Author)(*FUEL CELLS
OpenAIRE | Characterization of a new winter malting barley cu
Abstract. Ahil is a new winter malting barley cultivar developed by the method of experimental mutagenesis at the Institute of Agriculture, Karnobat, Bulgaria. Biological and agronomic characteristics of the cultivar were also investigated for several years and at the Executive Agency of Varietal Testing, Field Inspection and Seed Control trails in the period 2012 - 2013. Averaged for 6 locations in Bulgaria grain yield of the new cultivar was significantly higher than the yield of standard cultivars with about 5%. At the Institute of Agriculture grain yield was 17% higher than the average standard for the period of 5 years. The cultivar has high winter hardness, lodging resistance, resistance to powdery mildew and medium resistance to brown rust. Ahil has good malting quality

Managing to Make More Milk :: The Bullvine - The Dairy Information You Want To Know When You Need It
It would seem obvious that feed related factors would be most important when you set out to increase feed efficiency. Nutritionists and consultants draw our attention to forage digestibility, feed particle size, protein levels, fat levels, starch levels and certain feed additives that can affect feed efficiency. This is what they know. This is what we can control.. However, there are factors beyond feed that we can look at such as environmental factors and our own management inputs. Some environmental factors can be more difficult to control than others. It is difficult to be 100% in charge of the effects of heat stress, average days in milk, lactation number, acidosis and heat stress. Each one of these will affect feed conversion. But there are other environmental and management factors that we can target in our effort to improve feed conversion.. ...

Impact of Inoculation with Arbuscular Mycorrhizal, Phosphate Solubilizing Bacteria and Soil Yeast on Growth, Yield and...
Abstract: A factorial design experiment was conducted on field to investigate the effects of inoculation with AM fungi (Glomus mosseae), phosphate solubilizing bacteria strain (Bacillus polymyxa) and soil yeast strain (Saccharomyces cerevisiae) on growth, phosphorus content and yield of onion plants in calcareous soil under different levels of phosphorus fertilization (P1: 50, P2: 100 and P3: 200 kg ha-1). Results showed that inoculation with G. mosseae or B. polymyxa significantly (p = 0.05) increased plant height, shoot fresh and dry weights, root fresh and dry weights, average bulb diameter and total yield. The highest total yield and average bulb diameter were obtained from the inoculation treatment of AM fungus G. mosseae, recording 14.4 and 40.8% increases, respectively over the uninoculated control. Also, inoculation with AM fungus (G. mosseae) had a significant increase in all mineral content in onion plant compared with uninoculated control or other biofertilizers inoculation treatments ...
Integrative molecular profiling indicates a central role of transitory starch breakdown in establishing a stable C/N...
The variation of growth and cold tolerance of two natural Arabidopsis accessions, Cvi (cold sensitive) and Rschew (cold tolerant), was analysed on a proteomic, phosphoproteomic and metabolomic level to derive characteristic information about genotypically distinct strategies of metabolic reprogramming and growth maintenance during cold acclimation. Growth regulation before and after a cold acclimation period was monitored by recording fresh weight of leaf rosettes. Significant differences in the shoot fresh weight of Cvi and Rschew were detected both before and after acclimation to low temperature. During cold acclimation, starch levels were found to accumulate to a significantly higher level in Cvi compared to Rschew. Concomitantly, statistical analysis revealed a cold-induced decrease of beta-amylase 3 (BAM3; AT4G17090) in Cvi but not in Rschew. Further, only in Rschew we observed an increase of the protein level of the debranching enzyme isoamylase 3 (ISA3; AT4G09020). Additionally, the cold response

AUSTRALIA: Divestment strategy of Joe White Maltings Limited | Food Industry News | just-food
Just one week after the company revealed H1 losses of A$10m after tax and exceptional charges, Joe White Maltings Limited has expressed its concern to become a single track operation, concentrating on its malt activities and divesting its struggling food business. The company did make A$355,000 in pre-tax net profits, but the managing director, Ian Fraser, explained that the earnings produced by the core malting business had been negatively offset by the troubled food division, which necessitated a A$9.04m write off. This meant that the food business would be split into three as the first step of a divestment plan.In a public statement, it was announced that the peanut operation at Kingarot, Joe Whites most saleable business, is to be sold to the Peanut Company of Australia (PCA) pending approval from the Australian Competition and Consumer Commission. Renshaw Foods, another part of Joe White Maltings Limited Food Product Division, has also been sold to Select Harvests Limited. A signed agreement

Burley ,Dave_Burley at compuserve.com, Subject: Home malting, cidery beer Brewsters: Keith Manefy says: ,Is the drying phase of malting barley absolutely necessary? Would it be= ,possible to germinate the barley to the required stage and then go ,straight to the brewery for mashing. = It is possible Keith, but then you would be using green malt and get a different result than with cured malt. The old time Dutch and Flemish Brewers used to ( and some may still for historical reasons) dry their malt at room temperature in lofts and call it wind malt. If it is dried quickly, I suspect it will have a very high enzyme content, especially beta amylase and the glucanases and proteases. Check out the HBD archives. Malting and Brewing Science says: Perhaps in the future there will be a market for pale malts that are only hand dry, i.e. contain perhaps 5-8% moisture. = Such materials would be much easier to use than green malt while retaining ...

150. Gamma-Aminobutyric acid (GABA)-A practical indicator for the detection of heterogeneities during malting?
ABSTRACT: Nowadays, very large malt batches are processed, which frequently leads to heterogeneities within the grain beds. As a result beta-glucanase activities, among others, vary within the batches, thus high beta-glucan concentrations remain unhydrolyzed in parts of the batches and can lead to lautering and filtration problems during the brewing process. The kernels enzyme activities mainly depend on their physiological status. Accordingly, the metabolic status of the seeds corresponds to a reliable marker for detecting heterogeneities in the grain beds and for predicting potential processing problems. Up to now, the Calcofluor method according to Carlsberg has been the only standardized method to determine the kernels homogeneity; however, its results are not very precise. In this study, malting trials under differing conditions were carried out to assess if gamma-aminobutyric acid (GABA) can be used as a reliable marker for determining the physiological status of the kernels. Malting ...

Malt - Wikipedia
Malting is the process of converting barley or other cereal grains into malt for use in brewing, distilling, or in foods and takes place in a maltings, sometimes called a malthouse, or a malting floor. The cereal is spread out on the malting floor in a layer of 8 to 12 cm (3 to 4.5 in) depth. The malting process starts with drying the grains to a moisture content below 14% and then storing for around six weeks to overcome seed dormancy. When ready, the grain is immersed or steeped in water two or three times for two or three days to allow the grain to absorb moisture and to start to sprout. When the grain has a moisture content of around 46%, it is transferred to the malting or germination floor, where it is constantly turned over for about four to six days while it is air-dried. The grain at this point is called green malt. The green malt is then dried and pre-toasted in an oven (or kiln) to the desired color and specification. Malts range in color from very pale through crystal ...
