Wild type CEN.PK113-7D grown with 20 g/L galactose. LiCl (10 mM, therapeutically relevant) added and samples analyzed at 0, 20, 40, 60 and 140 minutes after LiCl addition. Lithium inhibits phosphoglucomutase, affecting galactose uptake and growth.

(Submitter supplied) Wild type strain CEN.PK113-7D was grown in an aerobic batch cultivation with a start concentration of 20 g/L galactose. During exponential growth at a biomass concentration of 3 g dry weight/L LiCl was added to a concentration of 10 mM. Just before addition of LiCl (time 0) and 20, 40, 60 and 140 minutes after addition of LiCl samples were taken for transcription analysis. Lithium inhibits phosphoglucomutase whereby both galactose uptake and growth is strongly affected. more...

(Submitter supplied) The wild-type (grown on galactose or glucose) or msn2/4 mutant (grown on galactose) strains were grown aerobically. At time zero (generation 0) the sparge gas was switched from air to O2-free N2 and samples were harvested after 0 (aerobic control), 0.04, 0.08, 0.19, and 2 generations of anaerobic growth.

Analysis of catabolite-derepressed (galactose) wildtype JM43 and isogenic msn2/4 mutant KKY8 cells shifted to short-term anaerobiosis (2 generations). Msn2 and 4 are key stress factors. Results suggest Msn2/4 involvement in metabolic remodeling during acclimatization to short-term anaerobiosis.

Analysis of catabolite-repressed (glucose) or derepressed (galactose) wildtype JM43 cells shifted from aerobiosis to anaerobiosis (2 generations). Results identify metabolic remodeling that occurs during acclimatization to short-term anaerobiosis in galactose but not in glucose.

(Submitter supplied) Gene expression profiles of baker’s yeast during initial dough-fermentation were investigated using liquid fermentation media to obtain insights at the molecular level into rapid adaptation mechanisms of baker’s yeast. Results showed that onset of fermentation caused drastic changes in gene expression profiles within 15 min. Genes involved in the tricarboxylic acid (TCA) cycle were down-regulated and genes involved in glycolysis were up-regulated, indicating a metabolic shift from respiration to fermentation. more...

(Submitter supplied) Saccharomyces cerevisiae is unique among yeasts for its ability to grow rapidly in the complete absence of oxygen. S. cerevisiae is therefore an ideal eukaryotic model to study physiological adaptation to anaerobiosis. Recent transcriptome analyses have identified hundreds of genes that are transcriptionally regulated by oxygen availability but the relevance of this cellular response has not been systematically investigated at the key control level of the proteome. more...

(Submitter supplied) In this study we investigated the transcriptional response of the yeast Saccharomyces cerevisiae to potassium starvation. To this end yeast cells were grown for 60 min in media without potassium or in media with a standard potassium concnetration (50 mM KCl). Using Serial Analysis of Gene Expression (SAGE)-tag sequencing the effect of potassium starvation on the transcriptome was determined.

(Submitter supplied) In response to limited nitrogen and abundant carbon sources, diploid Saccharomyces cerevisiae strains undergo a filamentous transition in cell growth as part of pseudohyphal differentiation. Use of the disaccharide maltose as the principal carbon source, in contrast to the preferred nutrient monosaccharide glucose, has been shown to induce a hyper-filamentous growth phenotype in a strain deficient for GPA2 which codes for a Galpha protein component that interacts with the glucose-sensing receptor Gpr1p to regulate filamentous growth. more...

(Submitter supplied) In contrast to batch cultivation, chemostat cultivation allows the identification of carbon source responses without interference by carbon-catabolite repression, accumulation of toxic products, and differences in specific growth rate. This study focuses on the yeast Saccharomyces cerevisiae, grown in aerobic, carbon-limited chemostat cultures. Genome-wide transcript levels and in vivo fluxes were compared for growth on two sugars, glucose and maltose, and for two C2-compounds, ethanol and acetate. more...
