A model that predicts cell growth, lipid accumulation and substrate consumption of oleaginous fungi in chemostat cultures (Meeuwse et al. in Bioproc Biosyst Eng. doi: 10.1007/s00449-011-0545-8 , 2011) was validated using 12 published data sets for chemostat cultures of oleaginous yeasts and one published data set for a poly-hydroxyalkanoate accumulating bacterial species. The model could descri...

Proteins from intercellular fluid extracts of chemically stressed barley (Hordeum vulgare L.) leaves were separated by native polyacrylamide gel electrophoresis at alkaline or acid pH. Polyacrylamide gels contained Saccharomyces cerevisiae (bakers' yeast) or Schizosaccharomyces pombe (fission yeast) crude cell walls for assaying yeast wall lysis. In parallel, gels were overlaid with a suspensio...

Mead is a traditional drink that contains 8%-18% (v/v) of ethanol, resulting from the alcoholic fermentation of diluted honey by yeasts. Mead fermentation is a time-consuming process and the quality of the final product is highly variable. Therefore, the present investigation had two main objectives: first, to determine the adequate inoculum size of two commercial wine-making strains of Sacchar...

Black gram is one of the most indispensable components world food basket and growth health crop get influenced by biotic abiotic factors. Beneficial phyto-microbes are among them that influence growth, more particularly seed borne microbes comparatively beneficial, they pass from generation to associated with plants establishment development. In present study, twenty seed-borne yeasts were char...

The study was performed in a batch system in order to determine the effects of pH and temperature on growth and glycerol production kinetics of two indigenous wine yeast strains Saccharomyces cerevisiae Kalecik 1 and Narince 3. The highest values of dry mass and specific growth rate were obtained at pH 4.00 for both of the strains. Maximum specific glycerol production rates were obtained at pH ...

Studies of metabolic regulation in yeasts have a long history. Yeasts have served as models for the regulation of fermentaive metabolism. Yeasts differ in their partitioning of metabolism between respiration and fermentation, that is, between their use of oxygen and organic compounds as terminal electron acceptors. The respirative route is assumed to yield more ATP. Many yeasts carry out metabo...

Yeasts play an important role in the biology of the fruit fly, Drosophila melanogaster. In addition to being a valuable source of nutrition, yeasts affect D. melanogaster behavior and interact with the host immune system. Most experiments investigating the role of yeasts in D. melanogaster biology use the baker's yeast, Saccharomyces cerevisiae. However, S. cerevisiae is rarely found with natur...

background: saccharomyces boulardii (s. boulardii) is the best known probiotic yeast. the genetic engineering of this probiotic strain requires the availability of appropriate mutants to accept various gene constructs carrying different selection markers. as the auxotrophy selection markers are under focus, we have generated a ura3 auxotroph mutant of s. boulardii for use in further genetic man...

objective: fungal nail infection (onychomycosis) is a common disease in all communities consisting about 50 percent of nail disorders. yeasts are one of the important causative agents of onychomycosis. identification of the yeast species is important in the epidemiological and therapeutical point of views. the aim of the present study is the precise species identification of the pathogenic yeas...

For the differentiation of species of yeasts, considerable value is attached to the ability of aimilating various carbon sources for growth. Beijerinck (1889) introduced for this general purpose the auxanographic plate technique which was adapted by Lodder (1934) for the study of sugar assimilation in the nonfermenting strains of the asporogenous yeasts. Diddens and Lodder (1942) expanded its u...
