Expression data from Saccharomyces cerevisiae and Saccharomyces pastorianus var. carlsbergensis

ABSTRACT: 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.

Aneuploidy influences the gene expression profiles in Saccharomyces pastorianus group I and II strains during fermentation.

Project description:We report the gene expression profile of two polypolid Saccharomyces pastorianus, lager yeast strains, the Group I strain CBS1538 and the Group II strain W34/70. Saccharomyces pastorianus is a hybrid of Saccharomuyces cerevisiaie and Saccharomyces eubayanus. We report that the gene expression patterns are correlated with the gene copy number of S. cerevisiae and S. eubayanus alleles.

Saccharomyces pastorianus strains comparison

Project description:Saccharomyces pastorianus is the yeast used to make lager beer; it is known to be an interspecific hybrid formed by the fusion between S. cerevisiae and S. bayanus genomes. This data set queries 17 S. pastorianus strains, collected at various times over the last 125 years from various breweries located in different geographical locations, which were obtained from CBS and DBVPG culture collections. The data in this set represent array-CGH experiments performed with these strains, using "2-species" custom Agilent arrays (the "2-species" arrays contain probes spaced every ~2 kb across the whole genomes of both S. cerevisiae and S. bayanus; the probes are unique and specific for each genome). The data set also contains 3 self-self hybridizations (S. cerevisiae + S. bayanus DNA mixed together in equimolar amounts, then labeled green or red in separate reactions, then hybridized to the "2-species" arrays) used for normalization in CGH-Miner analysis. A strain or line experiment design type assays differences between multiple strains, cultivars, serovars, isolates, lines from organisms of a single species.

Enhanced flavour profiles through radicicol induced genomic variation in S. pastorianus lager yeast

Project description:We report the gene expression profile of two polypolid Saccharomyces pastorianus mutants obtained by random mutagenesis using radicicol. Mutants derived from the Group I strain CBS1538 and the Group II strain W34/70. Saccharomyces pastorianus is a hybrid of Saccharomuyces cerevisiaie and Saccharomyces eubayanus. We report changes in transcriptome of the mutants compared to their respective parental strain

Revealing the beneficial effect of protease supplementation to high gravity beer fermentations using “–omics” techniques

Project description:Addition of sugar syrups to the basic wort is a popular technique to achieve higher gravity in beer fermentations, but it results in dilution of the free amino nitrogen (FAN) content in the medium. The multicomponent protease enzyme Flavourzyme has beneficial effect on the brewer´s yeast fermentation performance during high gravity fermentations as it increases the initial FAN value and results in higher FAN uptake, higher specific growth rate, higher ethanol yield and improved flavour profile. In the present study, transcriptome and metabolome analysis were used to elucidate the effect on the addition of the multicomponent protease enzyme Flavourzyme and its influence on the metabolism of the brewer´s yeast strain Weihenstephan 34/70. The study underlines the importance of sufficient nitrogen availability during the course of beer fermentation. The applied metabolome and transcriptome analysis allowed mapping the effect of the wort sugar composition on the nitrogen uptake. Both the transcriptome and the metabolome analysis revealed that there is a significantly higher impact of protease addition for maltose syrup supplemented fermentations, while addition of glucose syrup to increase the gravity in the wort resulted in increased glucose repression that lead to inhibition of amino acid uptake and hereby inhibited the effect of the protease addition. Keywords: 21 Plato with two carbon sources (glucose and maltose) and with/without enzyme supplementation Fermentation, transcriptome and metabolome analysis of industrial lager beer yeast strain Weihenstephan 34/70

Transcription profiling of bottom-fermenting yeast Saccharomyces pastorianus KBY011 during a time series of lager beer fermentation in the wort

Project description:A transcriptome analysis of the bottom-fermenting yeast S. pastorianus KBY011 during a time course of lager beer fermentation in the wort was carried out (0, 2, 6, 8, 10, 14, 24, 34, 40, 52, 64, 120, and 156h). RNA preparation followed by DNA microarray analysis was performed for the yeast harvested from the yeast storage tank either just prior to, or just after the actual fermentation, as well as from 12 different time points during fermentation.
