The first stomach of ruminants. It lies on the left side of the body, occupying the whole of the left side of the abdomen and even stretching across the median plane of the body to the right side. It is capacious, divided into an upper and a lower sac, each of which has a blind sac at its posterior extremity. The rumen is lined by mucous membrane containing no digestive glands, but mucus-secreting glands are present in large numbers. Coarse, partially chewed food is stored and churned in the rumen until the animal finds circumstances convenient for rumination. When this occurs, little balls of food are regurgitated through the esophagus into the mouth, and are subjected to a second more thorough mastication, swallowed, and passed on into other parts of the compound stomach.

Fecal coliform elevated-temperature test: a physiological basis. (1/6171)

The physiological basis of the Eijkman elevated-temperature test for differentiating fecal from nonfecal coliforms was investigated. Manometric studies indicated that the inhibitory effect upon growth and metabolism in a nonfecal coliform at 44.5 degrees C involved cellular components common to both aerobic and fermentative metabolism of lactose. Radioactive substrate incorporation experiments implicated cell membrane function as a principal focus for temperature sensitivity at 44.5 degrees C. A temperature increase from 35 to 44.5 degrees C drastically reduced the rates of [14C]glucose uptake in nonfecal coliforms, whereas those of fecal coliforms were essentially unchanged. In addition, relatively low levels of nonfecal coliform beta-galactosidase activity coupled with thermal inactivation of this enzyme at a comparatively low temperature may also inhibit growth and metabolism of nonfecal coliforms at the elevated temperature.  (+info)

Haloanaerobacter salinarius sp. nov., a novel halophilic fermentative bacterium that reduces glycine-betaine to trimethylamine with hydrogen or serine as electron donors; emendation of the genus Haloanaerobacter. (2/6171)

A novel halophilic fermentative bacterium has been isolated from the black sediment below a gypsum crust and a microbial mat in hypersaline ponds of Mediterranean salterns. Morphologically, physiologically and genetically this organism belongs to the genus Haloanaerobacter. Haloanaerobacter strain SG 3903T (T = type strain) is composed of non-sporulating long flexible rods with peritrichous flagella, able to grow in the salinity range of 5-30% NaCl, with an optimum at 14-15%. The strain grows by fermenting carbohydrates or by using the Stickland reaction with either serine or H2 as electron donors and glycine-betaine as acceptor, which is reduced to trimethylamine. The two species described so far in the genus Haloanaerobacter are not capable of Stickland reaction with glycine-betaine + serine; however, Haloanaerobacter chitinovorans can use glycine-betaine with H2 as electron donor. Strain SG 3903T thus represents the first described strain in the genus Haloanaerobacter capable of the Stickland reaction with two amino acids. Although strain SG 3903T showed 67% DNA-DNA relatedness to H. chitinovorans, it is physiologically sufficiently different from the two described species to be considered as a new species which has been named Haloanaerobacter salinarius sp. nov.  (+info)

Mechanism of citrate metabolism in Lactococcus lactis: resistance against lactate toxicity at low pH. (5/6171)

Measurement of the flux through the citrate fermentation pathway in resting cells of Lactococcus lactis CRL264 grown in a pH-controlled fermentor at different pH values showed that the pathway was constitutively expressed, but its activity was significantly enhanced at low pH. The flux through the citrate-degrading pathway correlated with the magnitude of the membrane potential and pH gradient that were generated when citrate was added to the cells. The citrate degradation rate and proton motive force were significantly higher when glucose was metabolized at the same time, a phenomenon that could be mimicked by the addition of lactate, the end product of glucose metabolism. The results clearly demonstrate that citrate metabolism in L. lactis is a secondary proton motive force-generating pathway. Although the proton motive force generated by citrate in cells grown at low pH was of the same magnitude as that generated by glucose fermentation, citrate metabolism did not affect the growth rate of L. lactis in rich media. However, inhibition of growth by lactate was relieved when citrate also was present in the growth medium. Citrate did not relieve the inhibition by other weak acids, suggesting a specific role of the citrate transporter CitP in the relief of inhibition. The mechanism of citrate metabolism presented here provides an explanation for the resistance to lactate toxicity. It is suggested that the citrate metabolic pathway is induced under the acidic conditions of the late exponential growth phase to make the cells (more) resistant to the inhibitory effects of the fermentation product, lactate, that accumulates under these conditions.  (+info)

Antisense RNA strategies for metabolic engineering of Clostridium acetobutylicum. (6/6171)

We examined the effectiveness of antisense RNA (as RNA) strategies for metabolic engineering of Clostridium acetobutylicum. Strain ATCC 824(pRD4) was developed to produce a 102-nucleotide asRNA with 87% complementarity to the butyrate kinase (BK) gene. Strain ATCC 824(pRD4) exhibited 85 to 90% lower BK and acetate kinase specific activities than the control strain. Strain ATCC 824(pRD4) also exhibited 45 to 50% lower phosphotransbutyrylase (PTB) and phosphotransacetylase specific activities than the control strain. This strain exhibited earlier induction of solventogenesis, which resulted in 50 and 35% higher final concentrations of acetone and butanol, respectively, than the concentrations in the control. Strain ATCC 824(pRD1) was developed to putatively produce a 698-nucleotide asRNA with 96% complementarity to the PTB gene. Strain ATCC 824(pRD1) exhibited 70 and 80% lower PTB and BK activities, respectively, than the control exhibited. It also exhibited 300% higher levels of a lactate dehydrogenase activity than the control exhibited. The growth yields of ATCC 824(pRD1) were 28% less than the growth yields of the control. While the levels of acids were not affected in ATCC 824(pRD1) fermentations, the acetone and butanol concentrations were 96 and 75% lower, respectively, than the concentrations in the control fermentations. The lower level of solvent production by ATCC 824(pRD1) was compensated for by approximately 100-fold higher levels of lactate production. The lack of any significant impact on butyrate formation fluxes by the lower PTB and BK levels suggests that butyrate formation fluxes are not controlled by the levels of the butyrate formation enzymes.  (+info)

Temperature and pH conditions that prevail during fermentation of sausages are optimal for production of the antilisterial bacteriocin sakacin K. (7/6171)

Sakacin K is an antilisterial bacteriocin produced by Lactobacillus sake CTC 494, a strain isolated from Spanish dry fermented sausages. The biokinetics of cell growth and bacteriocin production of L. sake CTC 494 in vitro during laboratory fermentations were investigated by making use of MRS broth. The data obtained from the fermentations was used to set up a predictive model to describe the influence of the physical factors temperature and pH on microbial behavior. The model was validated successfully for all components. However, the specific bacteriocin production rate seemed to have an upper limit. Both cell growth and bacteriocin activity were very much influenced by changes in temperature and pH. The production of biomass was closely related to bacteriocin activity, indicating primary metabolite kinetics, but was not the only factor of importance. Acidity dramatically influenced both the production and the inactivation of sakacin K; the optimal pH for cell growth did not correspond to the pH for maximal sakacin K activity. Furthermore, cells grew well at 35 degrees C but no bacteriocin production could be detected at this temperature. L. sake CTC 494 shows special promise for implementation as a novel bacteriocin-producing sausage starter culture with antilisterial properties, considering the fact that the temperature and acidity conditions that prevail during the fermentation process of dry fermented sausages are optimal for the production of sakacin K.  (+info)

Metabolic engineering of a 1,2-propanediol pathway in Escherichia coli. (8/6171)

1,2-Propanediol (1,2-PD) is a major commodity chemical that is currently derived from propylene, a nonrenewable resource. A goal of our research is to develop fermentation routes to 1,2-PD from renewable resources. Here we report the production of enantiomerically pure R-1,2-PD from glucose in Escherichia coli expressing NADH-linked glycerol dehydrogenase genes (E. coli gldA or Klebsiella pneumoniae dhaD). We also show that E. coli overexpressing the E. coli methylglyoxal synthase gene (mgs) produced 1,2-PD. The expression of either glycerol dehydrogenase or methylglyoxal synthase resulted in the anaerobic production of approximately 0.25 g of 1,2-PD per liter. R-1,2-PD production was further improved to 0.7 g of 1,2-PD per liter when methylglyoxal synthase and glycerol dehydrogenase (gldA) were coexpressed. In vitro studies indicated that the route to R-1,2-PD involved the reduction of methylglyoxal to R-lactaldehyde by the recombinant glycerol dehydrogenase and the reduction of R-lactaldehyde to R-1, 2-PD by a native E. coli activity. We expect that R-1,2-PD production can be significantly improved through further metabolic and bioprocess engineering.  (+info)

TY - GEN. T1 - Mechanistic Models for Process Development and Optimization of Fed-batch Fermentation Systems. AU - Mears, Lisa. AU - Stocks, Stuart M.. AU - Albæk, Mads O. AU - Sin, Gürkan. AU - Gernaey, Krist. PY - 2016. Y1 - 2016. N2 - This work discusses the application of mechanistic models to pilot scale filamentous fungal fermentation systems operated at Novozymes A/S. For on-line applications, a state estimator model is developed based on a stoichiometric balance in order to predict the biomass and product concentration. This is based on on-line gas measurements and ammonia addition flow rate measurements. Additionally, a mechanistic model is applied offline as a tool for batch planning, based on definition of the process back pressure, aeration rate and stirrer speed. This allows the batch starting fill to be planned, taking into account the oxygen transfer conditions, as well as the evaporation rates of the system. Mechanistic models are valuable tools which are applicable for both ...

A possible option to meet the increased demand of forage for dairy industry is to use the agricultural by-products, such as corn stover. However, nutritional value of crop residues is low and we have been seeking technologies to improve the value. A feeding trial was performed to evaluate the effects of four levels of Saccharomyces cerevisiae fermentation product (SCFP; Original XP; Diamond V) on lactation performance and rumen fermentation in mid-lactation Holstein dairy cows fed a diet containing low-quality forage. Eighty dairy cows were randomly assigned into one of four treatments: basal diet supplemented with 0, 60, 120, or 180 g/d of SCFP per head mixed with 180, 120, 60, or 0 g of corn meal, respectively. The experiment lasted for 10 wks, with the first 2 weeks for adaptation. Dry matter intake was found to be similar (P > 0.05) among the treatments. There was an increasing trend in milk production (linear, P ≤ 0.10) with the increasing level of SCFP supplementation, with no effects on

Fermented food, enjoyed across the globe, conveys health benefits through lactic acid fermentation. The fermentation process can transform the flavor of food from the plain and mundane to a mouth-puckering sourness enlivened by colonies of beneficial bacteria and enhanced micronutrients. While fermented food like yogurt, sauerkraut and kefir are well-known many other lesser-known foods also benefit from the lactic acid fermentation process. Indeed, virtually every food with a complex or simple sugar content can be successfully fermented.. Born of both necessity and practicality, lactic acid fermentation proved to be not only an efficient method of preserving food for our ancestors, but also a critical one. Indeed, fermented food like sauerkraut, cheese, wine, kvass, soured grain porridge and breads often sustained tribes and villages during harsh winters when fresh food simply wasnt available let alone plentiful.. In many societies including our own where yogurt has been heralded as a health ...
Some of the more common and easily measured volatile compounds of wine were determined for three different fermentation temperatures. Maximum, minimum, and average are given for over 30 fermentations at each temperature [(50, 70, 91°F) or (10, 21, 33°C)] for two years. Volatile acidity and acetic acid were compared and found to be equivalent for all practical purposes. Total volatile esters increase at the middle temperatures, as do acetaldehyde, isoamyl, and active amyl alcohols. Acetic acid decreases in the middle fermentation temperature range. Isobutanol does not vary greatly with fermentation temperature. Ethanol decreases with increasing fermentation temperature. Both levo and meso 2,3-butanediol increase with increasing temperature of fermentation. Acetoin also increases greatly at the higher fermentation temperatures.. ...
A Multistage Fermentation System for Fundamental Anaerobic Digestion Research FRANK D. SCHAUMBURG, Senior Research Engineer British Columbia Research Council Vancouver, British Columbia EDWIN J.

Nitrogen content of grape musts strongly impacts on fermentation performance and wine metabolite production. As nitrogen is a limiting nutrient in most grape musts, nitrogen supplementation is a common practice that ensures yeast growth during fermentation. However, preferred nitrogen sources -as ammonium- repress the genes related to alternative nitrogen sources consumption, usually involved in aromatic compounds production. Here, we describe the effect of high ammonium doses in Saccharomyces cerevisiae fermentation performance and wine properties, and how it is affected by yeast co-inoculation in mixed (S. cerevisiae + Torulaspora delbrueckii) fermentations. In addition, an RNA-seq analysis allowed us to study the S. cerevisiae transcriptional response to ammonium nutrition and yeast interaction, demonstrating that T. delbrueckii presence affects the global S. cerevisiae transcriptional response, reducing ammonium effects at both phenotypic -fermentation kinetics and metabolite production- and ...

Get our best cocktail recipes, tips, and more when you sign up for our newsletter. Alcoholic Fermentation Alcoholic fermentation is carried out by single-celled fungi called yeasts and also by some bacteria. This figure shows that during alcoholic fermentation: The sugar glucose is broken down to the alcohol ethanol plus carbon dioxide. This organism dissimilates glucose by EDP producing pyruvic acid which is converted to ethanol by decarboxylation and dehydrogenation as in yeast. Some examples of products that undergo alcoholic fermentation include: Beer; Cider (For example, the distillation of beer wort creates whiskey, while the distillation of wine produces brandy.) All you need then is salt and time. 0 His work also included observations on putrefaction and fermentation , which he spoke of as sisters, on the nature of salts, and on the preparation of ...
Fermentation test in batch procedures for various biological processes (e.g. anaerobic digestion, anammox, dark fermentation, ethanol fermentation, etc.) are increasingly reconised as key experimental approaches for research studies and industrial applications. However, due to the nature of the microorganisms used in such studies, the batch tests often generate high variability between different laboratories, mainly due to a poor standardisation in experimental platform, experimental procedure, data interpretation, and presentation. As a consequence, much research is focused on standardisation of these tests; in this regard the automated batch fermentation system AMPTS II and Gas Endeavour are excellent experimental platforms as they minimise the human input and automatically measure, calculate, and present the data in a standardised way.. ...
Fermentation is a partial degradation of sugars or other organic fuel that occurs without the use of … Alcoholic drinks such as beer and wine contain ethanol. The mass movement of members of a species from one location to another, in order to follow more favourable conditions. Fermentation biology is an energy releasing process that brings about chemical changes in raw food. Research on the chemistry of alcoholic fermentation in the second half of the 19th and beginning of the 20th century greatly facilitated the progress of biochemistry in general (seeFERMENTATION). Maybe the cell happens to be on the moon, or maybe the cells owner is sprinting away from a lion and using up all the oxygen at the moment. Alcohol fermentation, also known as ethanol fermentation, is the anaerobic pathway carried out by yeasts in which simple sugars are converted to ethanol and carbon dioxide. But lactic acid fermentation, we use it to oxidize the NADH so we get more NAD+. alcoholic fermentation Definition: ...
A fermentation starter (called simply starter within the corresponding context, sometimes called a mother) is a preparation to assist the beginning of the fermentation process in preparation of various foods and fermented drinks. A starter culture is a microbiological culture which actually performs fermentation. These starters usually consist of a cultivation medium, such as grains, seeds, or nutrient liquids that have been well colonized by the microorganisms used for the fermentation. In descriptions of national cuisines, fermentation starters may be referred to by their national names: Qū (simplified: 曲; traditional: 麴, also romanized as chu) (China) Jiuqu (simplified Chinese: 酒曲; traditional Chinese: 酒麴; pinyin: jiǔ qū): the starter used for making Chinese alcoholic beverages Laomian (pinyin: laomian; literally: old dough pinyin: mianfei; literally: dough fat): Chinese sourdough starter commonly used in Northern Chinese cuisine, the sourness of the starter is commonly ...
Low fermentation temperatures are of importance to food and beverage industries working with Saccharomyces cerevisiae Therefore, the identification of genes demonstrating a positive impact on fermentation kinetics is of significant interest. A set of 121 mapped F1 progeny, derived from a cross between haploid strains BY4716 (a derivative of the laboratory yeast S288C) and wine yeast RM11-1a, were fermented in New Zealand Sauvignon Blanc grape juice at 12.5°. Analyses of five key fermentation kinetic parameters among the F1 progeny identified a quantitative trait locus (QTL) on chromosome I with a significant degree of linkage to maximal fermentation rate (Vmax) at low temperature. Independent deletions of two candidate genes within the region, FLO1 and SWH1, were constructed in the parental strains (with S288C representing BY4716). Fermentation of wild-type and deletion strains at 12.5 and 25° confirmed that the genetic linkage to Vmax corresponds to the S288C version of the FLO1 allele, as ...

Propionic acid fermentation is carried out by several bacteria that belong to the genus Propionibacterium and to the species Clostridium propionicum. During propionic acid fermentation, both sugar and lactate can be used as the initial substrate. When sugar is available, these bacteria use the EMP pathway to produce pyruvate; the pyruvate is carboxylated to oxalacetate by methyl malonyl coen-zyme-A (CoA) and then reduced to propionate via malate, fumarate, and succinate. The other end products of propionic fermentation are acetic acid and CO2 (Figure 3). In particular, the propionic acid fermentation of 3 mol of glucose produces 4 mol of propionic acid, 2 mol of acetic acid, 2 mol of CO2, and 12 mol of ATP. When lactate is the initial substrate, propionic fermentation results in the production of 2 mol of propionic acid, 1 mol of acetic acid, and 1 mol of CO2. In this process, 1 mol of ATP is generated per nine carbons, and because of this, propionic bacteria generally grow very slowly.. The ...

Iso-amyl acetate (the banana ester) production is increased by all the factors that increase esters in general in beer fermentations. Higher gravity worts, lower pitching rates, lower aeration rates and higher fermentation temperatures all promote ester production.. The factors that stimulate 4VG are largely the same as it is a yeast by-product just as iso-amyl acetate is - higher gravity worts, lower pitching rates, lower aeration rates and higher fermentation temperatures.. In addition, open fermentations have been found to stimulate both ester production and 4VG production in hefe-weizens fermented with a hefe-weizen specific yeast strain. Open fermentation also allows the brewer to skim the scum and top-crop the yeast, both of which are traditional practices. (Many commercial breweries have switched to cylindro-conical fermenters, however.) At home, fermenting in a bucket and opening it during the most active part of fermentation can be done. The bucket is not a shallow fermenter, as a ...
Response surface methodology involving Central Composite Design (CCD) was applied to evaluate the effect of additives and growth stimulators with salt on natural lactic acid fermentation of carrot at room temperature. The variables investigated in this study were salt (2% - 3%), Lactose, MgSO4 + MnSO4 and Mustard (1%,1.5% and 2%) ; and various responses involved were per cent titrable acidity (Lactic Acid), pH, per cent salt and Lactic Acid Bacterial count (LAB count). The statistical analysis of the results showed that, only the treatments having powdered mustard had an appreciable effect on lactic acid fermentation. The best results were obtained in the treatment with 2.5 % salt, 1.5 % lactose, 1.5 % MgSO4 + MnSO4 and 2.0 % mustard. These optimized concentrations increased titrable acidity (1.69% as compared to the lowest value of acidity obtained i.e. 1.50%), lowered pH (2.47 as compared to the highest value of pH obtained i.e.3.30) and increased LAB count (9 X 108 cfu/ml as compared to the ...
The fermentation parameters of production of nigerloxin, an inhibitor of lipoxygenase, through solid state fermentation by Aspergillus niger CFR-W-105 and its recovery was studied. Inhibitor production was influenced by the nature of the solid substrate, moisture content, incubation temperature, carbon, nitrogen, lipid and mineral supplements. Nigerloxin production was the highest when wheat bran was supplemented with 5% (w/w) trisodium citrate. The maximum nigerloxin obtained was 5.06 mg/g of dry wheat bran. Extraction of the fermented wheat bran using ethyl acetate under acidic pH range of 4-5.5 under agitated conditions resulted in maximum inhibitor recovery. Optimum time and temperature of extraction were determined to be 90 min and 30 8C, respectively.. ...
Lactic streptococci, classically regarded as homolactic fermenters of glucose and lactose, became heterolactic when grown with limiting carbohydrate concentrations in a chemostat. At high dilution rates (D) with excess glucose present, about 95% of the fermented sugar was converted to l-lactate. However, as D was lowered and glucose became limiting, five of the six strains tested changed to a heterolactic fermentation such that at D = 0.1 h(-1) as little as 1% of the glucose was converted to l-lactate. The products formed after this phenotypic change in fermentation pattern were formate, acetate, and ethanol. The level of lactate dehydrogenase, which is dependent upon ketohexose diphosphate for activity, decreased as fermentation became heterolactic with Streptococcus lactis ML(3). Transfer of heterolactic cells from the chemostat to buffer containing glucose resulted in the nongrowing cells converting nearly 80% of the glucose to l-lactate, indicating that fine control of enzyme activity is an ... Fermentation equipment must have a fermenter large enough to support the entire fermentation process. The material used for manufacturing of fermentation equipment must have a high tolerance to the pressure and gas generated during fermentation. Equipment must be made of non-corrosive material and should not react with the chemical used for fermentation. It must have an outlet for CO2 and an inlet for O2 if aerobic microbes are used for fermentation.. Fermentation equipment must be sealed from outside to avoid contamination and must be sterilized. Vendors are offering extra features such as temperature controlling and facility to add an anti-foaming agent to attract customers. A key feature that fermentation equipment must offer is to provide an aseptic means of withdrawal of the fermented product and introduction of culture sample.. The major stages of fermentation are media formulation, inoculum preparation, sterilization of ...

1,3-Propanediol (1,3-PDO) is important building blocks for the bio-based chemical industry, Klebsiella pneumoniae can be an attractive candidate for their production. However, 1,3-PDO production is high but productivity is generally low by K. pneumoniae. In this study, repeated fed-batch cultivation by a lactate and 2,3-butanediol (2,3-BDO) deficient mutant of K. pneumoniae were investigated for efficient 1,3-PDO production from industrial by-products such as crude glycerol. First, optimal conditions for repeated fed-batch fermentation of a ΔldhA mutant defective for lactate formation due to deletion of the lactate dehydrogenase gene (ldhA) were determined. Maximal 1,3-PDO production level and productivity obtained by repeated fed-batch fermentation under optimized conditions were 81.1 g/L and 3.38 g/L/h, respectively, and these values were successfully maintained for five cycles of fermentation without any loss of fermentation capacity. This results were much higher than that of the normal fed-batch

This Food Expo will also focus on the new trends and technologies in the fermentation technique. Fermentation is used in a wide range of food and beverage applications, and the technology for enhancing this process is continually evolving. Industrial fermentation is the intentional use of fermentation by microorganisms such as bacteria and fungi to make products useful to humans. Fermented products have applications as food as well as in general industry. Some commodity chemicals, such as acetic acid, citric acid, and ethanol are made by fermentation. The rate of fermentation depends on the concentration of microorganisms, cells, cellular components, and enzymes as well as temperature, pH and for aerobic fermentation oxygen. Product recovery frequently involves the concentration of the dilute solution. Nearly all commercially produced enzymes, such as lipase, invertase and rennet, are made by fermentation with genetically modified microbes. Hopefully, the Fermented Food Symposium will be helpful ...
ENGLISH ABSTRACT: Stuck alcoholic fermentations are a major enological problem for the international winemaking industry. Incomplete wine fermentations are frequently characterized by high residual fructose concentrations and the near-absence of residual glucose, a fact that is due to the glucophilic character of the wine yeast Saccharomyces cerevisiae. Wines with high contents of post fermentation sugar are very susceptible for microbial spoilage since residual fructose and/or glucose can be metabolized by bacteria and yeast to undesired by-products such as volatile acid and off-flavours, resulting in wine spoilage and considerable economic losses. It has been reported that stuck fermentations are usually caused by several synergistically acting inhibition factors, and the glucose to fructose ratio (GFR) is thought to play an important role in this context. This study is aimed at contributing towards a better understanding of this industrial problem, and at finding industrially applicable ...

The course Food fermentation covers a wide range of microbial and enzymatic processes involved in food and ingredient fermentation to achieve desirable characteristics such as prolonged shelf-life, improved safety, attractive flavour, nutritional enrichment and promotion of health. Major fermentation micro-organisms include lactic acid bacteria, moulds and yeasts. Industrial control of fermentation processes requires up-to-date knowledge of the physiology, metabolism and genetic properties of the fermenting microbes. Equally important is the knowledge of their functionality in relation to their desired impact on food quality, safety and shelf-life.

Contamination of bacteria in large-scale yeast fermentations is a serious problem and a threat to the development of successful biofuel production plants. Huge research efforts have been spent in order to solve this problem, but additional ways must still be found to keep bacterial contaminants from thriving in these environments. The aim of this project was to develop process conditions that would inhibit bacterial growth while giving yeast a competitive advantage. Lactic acid bacteria are usually considered to be the most common contaminants in industrial yeast fermentations. Our observations support this view but also suggest that acetic acid bacteria, although not so numerous, could be a much more problematic obstacle to overcome. Acetic acid bacteria showed a capacity to drastically reduce the viability of yeast. In addition, they consumed the previously formed ethanol. Lactic acid bacteria did not show this detrimental effect on yeast viability. It was possible to combat both types of bacteria by

The growth of the cellulosic ethanol industry is currently impeded by high production costs. One possible solution is to improve the performance of fermentation itself, which has great potential to improve the economics of the entire production process. Here, we demonstrated significantly improved productivity through application of an advanced fermentation approach, named self-cycling fermentation (SCF), for cellulosic ethanol production. The flow rate of outlet gas from the fermenter was used as a real-time monitoring parameter to drive the cycling of the ethanol fermentation process. Then, long-term operation of SCF under anaerobic conditions was improved by the addition of ergosterol and fatty acids, which stabilized operation and reduced fermentation time. Finally, an automated SCF system was successfully operated for 21 cycles, with robust behavior and stable ethanol production. SCF maintained similar ethanol titers to batch operation while significantly reducing fermentation and down times. This
Evaluation of fermentation kinetics of xylose to ethanol fermentation in the presence of acetic acid by Pichia stipitis: Modeling and experimental data comparison
A method is presented to directly characterize the yeast diversity in wine fermentations using denaturing gradient gel electrophoresis (DGGE) of polymerase chain reaction (PCR) amplified ribosomal RNA genes. PCR-DGGE analysis of a commercial sweet wine fermentation clearly profiled the shifts in microbial diversity that occurred throughout the fermentation. Botrytis populations identified in press pan samples were absent from the settling tank and ensuing fermentation samples. Indigenous yeasts including Candida, Metschnikowia, and Pichia species were distinguished in the early stages of the fermentation prior to emergence of a Saccharomyces population. Surprisingly, the PCR-DGGE signature of Candida species persisted well into the fermentation long after the development of a dominant Saccharomyces population. By direct identification of yeast populations, PCR-DGGE can provide a rapid and comprehensive view of the microbial diversity present in wine fermentations without the necessity for ...

TY - JOUR. T1 - Effects of aeration on flavor compounds in immobilized primary fermentation. AU - Virkajärvi, Ilkka. AU - Lindborg, Katri. AU - Kronlöf, Jukka. AU - Pajunen, Esko. PY - 1999. Y1 - 1999. N2 - Continuous immobilized primary fermentation has been studied since the last century, but has not yet fulfilled expectations. There are two main biological difficulties for continuous primary fermentation: achieving and maintaining the desired flavor and preventing contaminations. One traditional way of controlling the flavor of beer is by aeration of wort prior to pitching. We explored the effects of aeration in immobilized primary fermentation. The fermentation system used consisted of two packed bed reactors and a buffer tank between the reactors. An industrial wort and an industrial brewers yeast strain were used. The wort was aerated by mixing air into the wort stream just before the inlet of the first reactor (pre-column). The air was diluted with carbon dioxide and both were filtered ...

Yeast are the main drivers of quality beer making. Aeration is vigorous, and … Beer and wine are produced by fermenting glucose with yeast. Yeast mixed with sugar produces gas bubbles of CO 2. But careful, if you add too much sugar, the bottle will explode. Even after the yeast has created alcohol it can then combine with a fatty acid to create an ester. Now known as stock yeast, it is separated from the alcohol generated by the fermentation and stored in refrigerated tanks for the subsequent fermentation cultivation. The chemical reaction between yeast and sugar produces ethanol and carbon dioxide. However, even when oxygen is abundant, yeast cells prefer fermentation to aerobic respiration, provided a sufficient supply of sugar is available. Yeast ferment malt sugars, creating carbon dioxide and alcohol as by-products. Louis Pasteur started working with yeast fermentations in the late 1850s and was the first to recognize the relationship between the presence of yeast cells and the ...
