Journal ArticleDOI
Comparison of heterologous xylose transporters in recombinant Saccharomyces cerevisiae
TL;DR: Kinetic characterization and aerobic batch cultivation of strains expressing the Gxf1, Sut1 and At5g59250 transporters showed a direct relationship between transport kinetics and xylose growth, which confirmed the role of catabolite repression in regulation of native transportters.
Book ChapterDOI
Biotechnical use of polymerase chain reaction for microbiological analysis of biological samples.
TL;DR: PCR technology is described as a microbial detection method, PCR inhibitors in biological samples and various sample preparation techniques that can be used to facilitate PCR detection, by either separating the micro-organisms from PCR inhibitors and/or by concentrating themicro-organisms to detectable concentrations.
Journal ArticleDOI
Simultaneous saccharification and fermentation of steam-pretreated bagasse using Saccharomyces cerevisiae TMB3400 and Pichia stipitis CBS6054.
TL;DR: Ethanolic fermentation of steam‐pretreated sugarcane bagasse was assessed in a simultaneous saccharification and fermentation (SSF) set‐up using either Saccharomyces cerevisiae TMB3400, a recombinant xylose utilizing yeast strain, or Pichia stipitis CBS6054, a naturally xylosed yeast strain.
Journal ArticleDOI
Expression of the Gxf1 transporter from Candida intermedia improves fermentation performance in recombinant xylose-utilizing Saccharomyces cerevisiae.
TL;DR: The glucose/xylose facilitator Gxf1 from Candida intermedia was expressed in the recombinant xylose-fermenting Saccharomyces cerevisiae strain TMB 3057 and the new strain, TMB 3411, displayed approximately two times lower Km for xylOSE transport compared to a control strain not expressing Gxf 1.
Journal ArticleDOI
Isolation and characterization of acetic acid-tolerant galactose-fermenting strains of Saccharomyces cerevisiae from a spent sulfite liquor fermentation plant.
TL;DR: From a continuous spent sulfite liquor fermentation plant, two species of yeast were isolated, Saccharomyces cerevisiae and Pichia membranaefaciens, and one of the isolates, no. 3, was heavily flocculating and produced a higher ethanol yield from spent sulfites than did commercial baker's yeast.
