(Submitter supplied) To identify genes involved in acclimatization of yeast to non-lethal ethanol stress, S. cerevisiae strain W303-1A was grown separately at 0% and 6.5% (v/v) ethanol, and gene expression profiles were compared using microarray analysis. A t-test with a p-value of 0.05 was applied for differences in gene expression across unstressed and stressed replicates of W303-1A. There were 1049 genes with significant differences in expression. more...

(Submitter supplied) Saccharomyces spp. are widely used for ethanol production however fermentation productivity is negatively affected by the impact of ethanol accumulation on yeast metabolic rate and viability. This study used microarray and statistical two-way ANOVA analysis to compare and evaluate gene expression profiles of two previously generated ethanol-tolerant mutants, CM1 and SM1, with their parent, S. cerevisiae W303-1A, in the presence and absence of ethanol stress. more...

(Submitter supplied) In this study, using DNA microarray analysis, we compared the comprehensive expression profiles of two yeast trains, i.e, the previously obtained ethanol-adapted yeast strain and the parental strain as control (FY834), under the ethanol stress condition (YPD medium contained 10% ethanol). As a result, we identified certain genes and functional categories of the genes that are possible involved in growth under the ethanol stress condition.

(Submitter supplied) The engineering of Saccharomyces cerevisiae strains for lactose utilization has been attempted with the intent of developing high productivity processes for alcoholic fermentation of cheese whey. A recombinant S. cerevisiae flocculent strain that efficiently ferments lactose to ethanol was previously obtained by evolutionary engineering of an original recombinant that displayed poor lactose fermentation performance. more...
