Project description:Natural grape-juice fermentations involve the sequential development of different yeast species which strongly influence the chemical and sensorial traits of the final product. In the present study,we aimed to examine the transcriptomic response of Saccharomyces cerevisiae to the presence of Hanseniaspora guilliermondii wine fermentation.

Project description:Natural grape-juice fermentations involve the sequential development of different yeast species which strongly influence the chemical and sensorial traits of the final product. In the present study,we aimed to examine the transcriptomic response of Saccharomyces cerevisiae to the presence of Hanseniaspora guilliermondii wine fermentation. Paralell fermentations were carried out in natural grape-juice using S. cerevisiae for both single and mixed culture with a H. guilliermondii strain. For RNA extraction, cells were collected at 24h, 48h and 96 h from both fermentations

Project description:This research work investigates the expression of the genes involved in flavor compound production in three different Saccharomyces species (S. cerevisiae, S. bayanus var. uvarum and S. kudriavzevii) under low (12°C) and moderate fermentation temperatures (28°C).

Project description:Yeasts constitute a dietary source for the spotted wing drosophila (SWD) and produce compounds that attract these flies. The study of the chemical composition of the yeast communities associated with SWD should therefore help to understand the relationship between the biology of the insect and the yeast's metabolism. In the present study, the lipidome of five yeast species isolated from grapes infested by SWD (three <i>Hanseniaspora uvarum</i> strains, <i>Candida</i> sp., <i>Issatchenkia terricola</i>, <i>Metschnikowia pulcherrima</i> and <i>Saccharomycopsis vini</i>) and a laboratory strain of <i>Saccharomyces cerevisiae</i> was explored using an untargeted approach. Additionally, the lipid profile of two species, <i>S. cerevisiae</i> and <i>H. uvarum</i>, which were reported to elicit different responses on SWD flies based on feeding and behavioral trials, was compared with a chemical enrichment approach. Overall, 171 lipids were annotated. The yeast species could be distinguished from each other based on their lipid profile, except for the three strains of <i>H. uvarum,</i> which were very similar to each other. The chemical enrichment analysis emphasized diversities between <i>S. cerevisiae</i> and <i>H. uvarum</i>, that could not be detected based on their global lipid profile. The information concerning differences between species in their lipidome may be of interest to future entomological studies concerning the yeast-insect interaction and could help to explain the responses of SWD to diverse yeast species.

Project description:This is genome-scale metabolic model of Hanseniaspora uvarum as the representative species for the clade Saccharomycodaceae. This model was generated through homology search using a fungal pan-GEM largely based on Yeast8 for Saccharomyces cerevisiae, in addition to manual curation. This model has been produced by the Yeast-Species-GEMs project from Sysbio (www.sysbio.se). This is model version 1.0.0 accompanying the publication (DOI: 10.15252/msb.202110427), currently hosted on BioModels Database and identified by MODEL2109130013. Further curations of this model will be tracked in the GitHub repository: https://github.com/SysBioChalmers/Yeast-Species-GEMs Models for species of the same clade includes: Hanseniaspora uvarum; Hanseniaspora valbyensis; Hanseniaspora vineae; Hanseniaspora osmophila; Hanseniaspora clermontiae; Kloeckera hatyaiensis; Hanseniaspora pseudoguilliermondii; Hanseniaspora singularis.

Project description:Four hybrid yeast strains isolated from a variety of industrial substrates were hybridized to an array-CGH platform containing probes to query the whole genomes of seven different Saccharomyces species. For most of the strains we found evidence of multiple interspecific hybridization events and multiple introgressed regions. The strains queried were GSY205 (isolated from a cider fermentation), GSY505 (a contaminant from a lager beer fermentation), GSY2232 (a commercial wine yeast strain), and GSY312 (a commercial lager beer strain). Additionally, 3 different rare viable spores derived from laboratory-created interspecific S. cerevisiae-S. bayanus (aka S. uvarum) hybrids were queried, before and after evolution in chemostats, via S. cerevisiae-S. bayanus microarrays.

Project description:High concenHigh concentration acetic acid in the fermentation medium represses cell growth, metabolism and fermentation efficiency of Saccharomyces cerevisiae, which is widely used for cellulosic ethanol production. Our previous study proved that supplementation of zinc sulfate in the fermentation medium improved cell growth and ethanol fermentation performance of S. cerevisiae under acetic acid stress condition. However, the molecular mechanisms is still unclear. To explore the underlying mechanism of zinc sulfate protection against acetic acid stress, transcriptomic and proteomic analysis were performed. The changed genes and proteins are related to carbon metabolism, amino acid biosynthesis, energy metabolism, vitamin biosynthesis and stress responses. In a total, 28 genes showed same expression in transcriptomic and proteomic data, indicating that zinc sulfate affects gene expression at posttranscriptional and posttranslational levels.tration acetic acid in the fermentation medium represses cell growth, metabolism and fermentation efficiency of Saccharomyces cerevisiae, which is widely used for cellulosic ethanol production.
