Project description:A propolis-resistant Saccharomyces cerevisiae mutant strain was obtained using an evolutionary engineering strategy based on successive batch cultivation under gradually increasing propolis levels. The mutant strain FD 11 was selected at a propolis concentration that the reference strain could not grow at all. Whole-genome transcriptomic analysis of FD11 was performed with respect to its reference strain to determine differences in gene expression levels between the two strains. Saccharomyces cerevisiae

Transcriptomic analysis of a caffeine-resistant Saccharomyces cerevisiae strain obtained by evolutionary engineering

Project description:A caffeine-resistant Saccharomyces cerevisiae mutant strain was obtained using an evolutionary engineering strategy based on successive batch cultivation at gradually increasing caffeine levels. The mutant strain Caf905-2 was selected at a caffeine concentration where its reference strain could not grow at all. Whole-genome transcriptomic analysis of Caf905-2 was performed with respect to its reference strain.

Effect of the antifungal protein PeAfpA in the expression profile of Saccharomyces cerevisiae BY4741 strain.

Project description:Transcriptomic study to characterize the interaction of the Penicillium expansum antifungal protein PeAfpA with the the model yeast Saccharomyces cerevisiae. For this, the transcriptome of S. cerevisiae BY4741 strain was compared among samples treated with increasing concentrations of PeAfpA.

Expression data from Saccharomyces cerevisiae and Saccharomyces pastorianus var. carlsbergensis

Project description:During fermentation Saccharomyces yeast produces various aroma-active metabolites determining the different characteristics of aroma and taste in fermented beverages. Amino acid utilization by yeast during brewer´s wort fermentation is seen as linked to flavour profile. To better understand the relationship between the biosynthesis of aroma relevant metabolites and the importance of amino acids, DNA microarrays were performed for Saccharomyces cerevisiae strain S81 and Saccharomyces pastorianus var. carlsbergensis strain S23, respectively. Thereby, changes in transcription of genes were measured, which are associated with amino acid assimilation and its derived aroma-active compounds during fermentation.

Expression data from Saccharomyces cerevisiae

Project description:Saccharomyces cerevisiae is an excellent microorganism for industrial succinic acid production, but high succinic acid concentration will inhibit the growth of Saccharomyces cerevisiae then reduce the production of succinic acid. Through analysis the transcriptomic data of Saccharomyces cerevisiae with different genetic backgrounds under different succinic acid stress, we hope to find the response mechanism of Saccharomyces cerevisiae to succinic acid.

Expression profiling of various colony phenotypes of wild Saccharomyces cerevisiae strain

Project description:Transcriptome comparison of cells from 4 and 7 day-old microcolonies of wild Saccharomyces cerevisiae BR-F strain, 4 and 7 day-old microcolonies of feral BR-RF strain and 4- and 7 day-old microcolonies of domesticated BR-S strain. All colonies grown on solid complex media with glycerol as carbon source. The aim of the study was to identify genes required for fluffy (structured) colony formation as well as the genes specific for certain phenotypic variant. BR-F is wild strain isolated from natural habitat and forms structured colonies when grown on media with non-fermentable carbon source. BR-S strain arose by phenotypic switch from the original wild BR-F strain during the cultivation of BR-F strain under rich and favourable conditions (process of so-called domestication), forms smooth colonies. BR-RF strain is derived from the domesticated BR-S strain under adverse conditions and restores the formation of structured colonies and other properties of original wild BR-F strain.
