ISOLATION AND IDENTIFICATION OF YEAST STRAINS FROM SUGARCANE MOLASSES, DATES AND FIGS FOR ETHANOL PRODUCTION UNDER CONDI...
ABSTRACT Yeast strains were isolated from sugar cane molasses (S1), dates (S2) and figs (S3) and the ethanol production was evaluated in batch condition. A comparison was made with the yeast Saccharomyces cerevisiae. The strains showed tolerant characteristics to stressful conditions like salinity and ethanol. The isolated strains produced ethanol;...
Effect of high Cu2+ stress on fermentation performance and copper biosorption of Saccharomyces cerevisiae during wine fe...
Abstract The effect of high Cu2+ stress on fermentation performance and copper biosorption of Saccharomyces cerevisiae BH8 during wine fermentation was investigated in this paper. Under high Cu2+ stress, the cell growth and survival rate of yeast BH8 were inhibited. With different copper concentration, the effect on cell growth of yeast BH8 was dif...
Diversity of yeasts during fermentation of cocoa from two sites in the Brazilian Amazon
ABSTRACT The purpose of this study was to identify the yeasts involved in spontaneous fermentation of cocoa from the Brazilian Amazon region. The fermentation process was carried out experimentally with cocoa seeds from two sites (Medicilândia and Tucumã), State of Pará, northern Brazil, during a six-day period. Totals of 44 yeasts were isolated fr...
Enhanced ethanol production from industrial lignocellulose hydrolysates by a hydrolysate-cofermenting Saccharomyces cere...
Published in Bioprocess and Biosystems Engineering
Industrial production of lignocellulosic ethanol requires a microorganism utilizing both hexose and pentose, and tolerating inhibitors. In this study, a hydrolysate-cofermenting Saccharomyces cerevisiae strain was obtained through one step in vivo DNA assembly of pentose-metabolizing pathway genes, followed by consecutive adaptive evolution in pent...
Increase ethyl acetate production in Saccharomyces cerevisiae by genetic engineering of ethyl acetate metabolic pathway
Published in Journal of Industrial Microbiology & Biotechnology
Ethyl acetate has attracted much attention as an important chemical raw material and a flavor component of alcoholic beverages. In this study, the biosynthetic pathway for the production of ethyl acetate in Chinese liquor yeast was unblocked. In addition to engineering Saccharomyces cerevisiae to increased intracellular CoA and acetyl-CoA levels, w...
Yeast Expression Systems: Overview and Recent Advances
Published in Molecular Biotechnology
Yeasts are outstanding hosts for the production of functional recombinant proteins with industrial or medical applications. Great attention has been emerged on yeast due to the inherent advantages and new developments in this host cell. For the production of each specific product, the most appropriate expression system should be identified and opti...
RNA-seq based transcriptional analysis of Saccharomyces cerevisiae and Lachancea thermotolerans in mixed-culture ferment...
Published in BMC Genomics
BackgroundIn wine fermentation starter cultures, the blending of non-Saccharomyces yeast with Saccharomyces cerevisiae to improve the complexity of wine has become common practice, but data regarding the impact of co-cultivation on yeast physiology and on genetic and metabolic regulation remain limited. Here we describe a transcriptomic analysis of...
Nitric oxide increases biofilm formation in Saccharomyces cerevisiae by activating the transcriptional factor Mac1p and ...
Published in Biotechnology for Biofuels
BackgroundBiofilms with immobilized cells encased in extracellular polymeric substance are beneficial for industrial fermentation. Their formation is regulated by various factors, including nitric oxide (NO), which is recognized as a quorum-sensing and signal molecule. The mechanisms by which NO regulates bacterial biofilms have been studied extens...
Transcriptional regulation of the genes involved in protein metabolism and processing in Saccharomyces cerevisiae.
Topological analysis of large networks, which focus on a specific biological process or on related biological processes, where functional coherence exists among the interacting members, may provide a wealth of insight into cellular functionality. This work presents an unbiased systems approach to analyze genetic, transcriptional regulatory, and phy...
