The interest in new beer products, which has been growing for several years, forces technologists and brewers to look innovative raw materials, such as hops, sources of carbohydrates or yeast. aim the presented study was evaluate effect selected Saccharomyces (Saccharomyces paradoxus (CBS 7302), S. kudriavzevii 3774), cerevisiae (Safbrew T-58)) non-Saccharomyces yeast (W. anomalus 5759), Ha. uv...

Consumers’ increasing interest in sparkling wine has enhanced the global market’s demand. The pro-technological yeasts strains selected for formulation of microbial starter cultures are a fundamental parameter exalting quality and safety final product. Nowadays, management employed resource is highly requested by stakeholders, because economic importance this oenological sector. Here, we report...

Yeast researchers need model systems for ecology and evolution, but the model yeast Saccharomyces cerevisiae is not ideal because its evolution has been affected by domestication. Instead, ecologists and evolutionary biologists are focusing on close relatives of S. cerevisiae, the seven species in the genus Saccharomyces. The best-studied Saccharomyces yeast, after S. cerevisiae, is S. paradoxu...

In view of the increase in Saccharomyces cerevisiae mannan content, the culture condition for S.cerevisiae were optimized in this study. The influence of culture condition such as original pH, inoculum size, and temperature on mannan production were evaluated using Response surface methodology. The mathematical model was established by the quadratic rotary combination design. with the order of ...

background: chronic myeloid leukemia is a common cancer in human and chemical therapy is a routine method for treatment that has some side effects. so the goal of this study was the use of natural compound such as cell wall obtained from saccharomyces cerevisiae ( s. cerevisiae ) and saccharomyces boulardi ( s. boulardi ) and iron nanoparticles on the growth inhibition of k562 cell line. method...

The budding yeast Saccharomyces cerevisiae is a valuable model system for studying prion-prion interactions as it contains multiple prion proteins. A recent study from our laboratory showed that the existence of Swi1 prion ([SWI(+)]) and overproduction of Swi1 can have strong impacts on the formation of 2 other extensively studied yeast prions, [PSI(+)] and [PIN(+)] ([RNQ(+)]) (Genetics, Vol. 1...

Evidence is rapidly accumulating that hybridization generates adaptive variation. Transgressive segregation in hybrids could promote the colonization of new environments. Here, we use an assay to select hybrid genotypes that can proliferate in environmental conditions beyond the conditions tolerated by their parents, and we directly compete them against parental genotypes in habitats across env...

When the growth rate of the yeast Saccharomyces cerevisiae is limited with various nitrogen sources, the duration of the S phase is proportional to cell cycle length over a fourfold range of growth rates (C.J. Rivin and W. L. Fangman, 1980, J. Cell Biol. 85:96-107). Molecular parameters of the S phases of these cells were examined by DNA fiber autoradiography. Changes in replication fork rate a...

Saccharomyces cerevisiae. required for oxidative metabolism in mitochondrial intermediate peptidase gene, is MIP1, a new yeast gene homologous to the rat
