Overexpression of PDE2 or SSD1-V in Saccharomyces cerevisiae W303-1A strain renders it ethanol-tolerant

Improvement of ethanol production by ethanol-tolerant Saccharomyces cerevisiae UVNR56

Ethanol tolerance is one of the important characteristics of ethanol-producing yeast. This study focused on the improvement of ethanol tolerance of Saccharomyces cerevisiae NR1 for enhancing ethanol production by random UV-C mutagenesis. One ethanol-tolerant mutant, UVNR56, displayed a significantly improved ethanol tolerance in the presence of 15% (v/v) ethanol and showed a considerably higher...

Whole-Genome Sequence and Variant Analysis of W303, a Widely-Used Strain of Saccharomyces cerevisiae

The yeast Saccharomyces cerevisiae has emerged as a superior model organism. Selection of distinct laboratory strains of S. cerevisiae with unique phenotypic properties, such as superior mating or sporulation efficiencies, has facilitated advancements in research. W303 is one such laboratory strain that is closely related to the first completely sequenced yeast strain, S288C. In this work, we p...

Saccharomyces cerevisiae SSD1-V confers longevity by a Sir2p-independent mechanism.

The SSD1 gene of Saccharomyces cerevisiae is a polymorphic locus that affects diverse cellular processes including cell integrity, cell cycle progression, and growth at high temperature. We show here that the SSD1-V allele is necessary for cells to achieve extremely long life span. Furthermore, addition of SSD1-V to cells can increase longevity independently of SIR2, although SIR2 is necessary ...

Disruption of GAL1 Gene in Saccharomyces cerevisiae Leads to Higher Ethanol Production

Overexpression of a truncated form of the MSN2 gene enhances the initial rate of ethanol production in an industrial fuel-ethanol Saccharomyces cerevisiae strain

Background The yeast strain CAT-1 isolated from a Brazilian fuelethanol plant (Babrzadeh et al. 2009) is one of the most common strain used nowadays due to its very efficient fermentation capacity, especially at high sugar concentrations and under the stressful industrial conditions. Since the transcription factor genes MSN4, MSN2, YAP1 and HSF1 of tolerant yeast strains are highly expressed un...
