Transcriptomatic and proteomic approach for understanding the molecular basis of adaption of Saccharamyces cerevisiae to wine fermentation

Article Abstract:

A study is conducted on the several stress conditions undergone by the Saccharomyces cerevisiae cells throughout alcoholic fermentation. It is observed the transcriptomatic and proteomic comparison between two commercial strains showed different fermentive behaviors that could be related to differences in the mRNA and protein profiles.

Genome-wide screen for oxalate-sensitive mutants of Saccharomyces cerevisiae

Article Abstract:

A genetic screening of a Saccharomyces cerevisiae deletion library for mutants sensitive to oxalic acid is presented. Findings suggest that the sensitivity of the rib4[DELTA] mutant, a riboflavin auxotroph is due to oxalate-mediated interference with riboflavin uptake by the putative monocarboxylate transporter Mch5.

Exposure of Saccharomyces cerevisiae to acetaldehyde induces sulfur amino acid metabolism and polyamine transporter genes, which depend on Met4p and Haa1p reanscription factors, respectively

Article Abstract:

Saccharomyces cerevisiae when subjected to acetaldehyde produces sulfur amino acid metabolism genes and polyamine transporter genes. Results indicate that the activation of the sulfur amino-acid metabolism genes by acetaldehyde depends on Met4p and Met31/32p and polyamine transporter induction depends on Haa1p.
