Regulation of endo-polygalacturonase activity in Saccharomyces cerevisiae.
TL;DR: This study attempted to elucidate how pectolytic activity is regulated in S. cerevisiae and to determine whether the means of regulation differ between strains, and found not to be regulated by sequence differences in the PGU1 gene, but by the transcription level of the gene.

Redox cofactor metabolism in Saccharomyces cerevisiae and its impact on the production of alcoholic fermentation end-products.
TL;DR: In this paper , the authors explored the redox status dynamics and NAD(H) and NADP(H)-cofactor ratios throughout alcoholic fermentation in four S. cerevisiae strains that exhibit different carbon metabolic fluxes.

Comparative morphological characteristics of three Brettanomyces bruxellensis wine strains in the presence/absence of sulfur dioxide
TL;DR: Fluorescence microscopy demonstrated a decrease in metabolic activity and the appearance of inclusion body-like structures in the cells following exposure to SO2, for the first time in this yeast.

The carbon consumption pattern of the spoilage yeast Brettanomyces bruxellensis in synthetic wine-like medium.
Brendan D. Smith,Benoit Divol +1 more
TL;DR: The study confirms that B. bruxellensis is able to survive using limited amount of nutrients, making this yeast a challenge for winemakers.

Transcriptomics unravels the adaptive molecular mechanisms of Brettanomyces bruxellensis under SO2 stress in wine condition
F. Valdetara,Miha Skalic,Daniela Fracassetti,Marli Louw,Concetta Compagno,Maret du Toit,Roberto Foschino,Uroš Petrovič,Benoit Divol,Ileana Vigentini +9 more
TL;DR: The transcriptomics variation in response to SO2 stress confirmed the strain-related response in B. bruxellensis and the GO analysis of common differentially expressed genes showed that the detoxification process carried out by SSU1 gene can be considered as the principal specific adaptive response to counteract the SO2 presence.
