A genetic approach of wine yeast fermentation capacity in nitrogen-starvation reveals the key role of nitrogen signaling.

ABSTRACT: In conditions of nitrogen limitation, Saccharomyces cerevisiae strains differ in their fermentation capacities, due to differences in their nitrogen requirements. A population of 133 individuals from the F2 segregant population from a cross between two strains with different nitrogen requirements for efficient fermentation has been analyzed for their fermentation capacities. Two groups of 15 strains were defined, one group of High and one of Low Nitrogen requirement. These two groups are compared in order to detect genomic regions involved in the differences of nitrogen requirement. We used a custom isothermal array that has been designed for the detection of SNP at 6317 position on RM11.1a genome sequence http://www.broadinstitute.org/annotation/genome/saccharomyces_cerevisiae.3/Home.html) and obtained from the comparison with the genome sequence of strain Saccharomyces P3-D5.

Regulation involved in difference in nitrogen requirements of Saccharomyces cerevisiae wine yeasts in alcoholic fermentation

Project description:The objective of this work is to identify, in enological condition, differences in transcriptomic regulation that may explain the differences in strains fermentation properties. For this, we compared the global expression patterns of 8 Saccharomyces cerevisiae strains with different nitrogen requirement (L2868, 4CAR1, Fermiflor, Zymasil, MTF1782, 7013, K1M, EC1118). The transcriptome was analyzed on cells fermenting in a nitrogen limited medium containing 100mg.l-1 assimilable nitrogen (SM100) and harvested at stationary phase (45g/L of CO2 produced and corresponding to 6% ethanol). At this stage the strains exhibited differences in fermentation rates. Moreover, the transcriptome was shown to be rather stable at this stage since growth was stopped for all cells and nutrients have been depleted (Rossignol et al. 2003).

Comparative phenotypic and genome-wide expression analysis of ancestral Saccharomyces cerevisiae and a strain with higher flux through the pentose phosphate pathway

Project description:By an evolutionary approach based on long-term culture on gluconate as the sole carbon source, a Saccharomyces cerevisiae wine strains with enhanced flux through the pentose phosphate (PP) pathway were obtained. One of these evolved strains, ECA5, exhibited several novel properties with great potential for wine making, including a higher than wild-type fermentation rate and altered production of acetate and aroma compounds. To describe the mechanisms underlying this complex phenotype, we performed a comparative analysis of transcriptomic profiles between ECA5 and its ancestral strain, EC1118, under low nitrogen, wine fermentation conditions.

Transcriptomic analyses of three wine yeast strains duting their response to nitrogen availability

Project description:A time-course transcriptomic experiment was performed in three geographically different wine yeast strains in order to test differences in gene expression as response to different nitrogen availability mRNA amounts for different wine yeast strains at different nitrogen availability was determined along the fermentation of a syntethic must. mRNA determinations were made at different fermentation stages (12, 24, 36 and 96 h after innoculation) Please note that there are two replicates per each stage (i.e. two raw data files per each sample; R1.txt and R2.txt) and the data were combined to generate the normalized data for each stage (i.e. sample).

Functional genomic analysis of a commercial wine strain of Saccharomyces cerevisiae under differing nitrogen conditions.

Project description:DNA microarray analysis was used to profile gene expression in a commercial isolate of Saccharomyces cerevisiae grown in a synthetic grape juice medium under conditions mimicking a natural environment for yeast: High-sugar and variable nitrogen conditions. The high nitrogen condition displayed elevated levels of expression of genes involved in biosynthesis of macromolecular precursors across the time course as compared to low-nitrogen. In contrast, expression of genes involved in translation and oxidative carbon metabolism were increased in the low-nitrogen condition, suggesting that respiration is more nitrogen-conserving than fermentation. Several genes under glucose repression control were induced in low-nitrogen in spite of very high (17%) external glucose concentrations, but there was no general relief of glucose repression. Expression of many stress response genes was elevated in stationary phase. Some of these genes were expressed regardless of the nitrogen concentration while others were found at higher levels only under high nitrogen conditions. A few genes, FSP2, RGS2, AQY1, YFL030W, were expressed more strongly with nitrogen limitation as compared to other conditions.

Physiological and genomic analysis of Saccharomyces cerevisiae artificial hybrids with improved fermentation performance and mannoprotein release capacity

Project description:Yeast mannoproteins contribute to several aspects of wine quality by protecting wine against protein haze, reducing astringency, retaining aroma compounds and stimulating growth of lactic-acid bacteria. The selection of a yeast strain simultaneously overproducing mannoproteins and showing good fermentative characteristics is a difficult task. In this work, a Saccharomyces cerevisiae x Saccharomyces cerevisiae hybrid bearing the two oenologically relevant features was constructed and a reduction in the amount of bentonite necessary for wine stabilization was observed for wines fermented with the generated strain. Additionally, different copy numbers of some genes probably related with these physiological features were detected in this hybrid. Hybrid share with parental Sc1 similar copy number of genes SPR1, SWP1, MNN10 and YPS7 related to cell wall integrity and with parental Sc2 similar copy number of some glycolytic genes as GPM1 and HXK1 as well as genes involved in hexose transport as HXT9, HXT11 and HXT12. This work demonstrates that artificial hybridization and stabilization in winemaking conditions constitute an effective approach to obtain yeast strains with desirable physiological features as mannoprotein overproducing capacity and improved fermentation performance, characteristics genetically depending on the coordinated expression of a multitude of different genes. In this work, genetically stable mannoprotein overproducing Saccharomyces cerevisiae strains simultaneously showing excellent fermentation capacities were obtained by hybridization methods giving rise to non-GMO strains. The potential relationship between the copy number of specific genes and the improved features was also evaluated by means of aCGH analysis of parental and hybrid strains.

Aspergillus niger exposed to combinations of carbon source, nitrogen source, nitrogen concentration, and culture pH

Project description:Microarray analysis of Aspergillus niger under conditions with differing combinations of carbon source, nitrogen source, nitrogen concentration, and culture pH Fermentor cultures were grown in minimal medium (MM) at a constant temperature of 30 ± 0.5 ºC and with differing combinations of carbon source (either 277.5 mM glucose or 333.0 mM xylose), nitrogen source (NH4Cl or NaNO3) and nitrogen concentration (4x: 282.4 mM; 8x: 564.8 mM), and pH (pH4 or pH5) of the medium (M. Braaksma, A.K. Smilde, M.J. van der Werf, P.J. Punt, submitted for publication). At different time points samples were collected, quenched immediately in methanol at -45 ºC and centrifuged at -20 ºC to remove supernatant. Part of the biomass was frozen into liquid nitrogen and stored at -80 ºC for microarray analysis. For each of the 16 culture conditions one sample was selected for microarray analysis; samples were collected either around the time point carbon source depleted or a considerable time (~24 h) after carbon souce depletion. In addition some technical duplicates were included. 20 samples were analyzed from 16 different fermentation conditions. The fermentation conditions were varied according to a full factorial design of four factors tested at two levels. From one fermentation two different time samples were analyzed, from another fermentation four samples, two technical replicates of two different time samples, were analyzed. Samples were collected either around the time point carbon source depleted or a considerable time (~24 h) after carbon souce depletion.
