(Submitter supplied) Industrial bioethanol production may involve a low pH environment,improving the tolerance of S. cerevisiae to a low pH environment caused by inorganic acids may be of industrial importance to control bacterial contamination, increase ethanol yield and reduce production cost. Through analysis the transcriptomic data of Saccharomyces cerevisiae with different ploidy under low pH stress, we hope to find the tolerance mechanism of Saccharomyces cerevisiae to low pH.

(Submitter supplied) The xylose fermentation capability of an industrainl Saccharomyces cerevisiae strain was enhanced by adaptive evolution. Eight homozygots were generated by tetrads dissection. The underlying molecular basis of the enhanced xylose fermentation capability was analyzed.

(Submitter supplied) The main objective is to develop a strain tolerant to furfural for ethanol production from lignocellulosic hydrolysates. We compare gene expressions among three genetically modified S. cerevisiae (control, TAL-expressing and TAL-ADH expressing strain) under the presence and absence of furfural.

(Submitter supplied) The vanillin tolerance Saccharomyces cerevisiae was screened and compared intracellular ergosterol levels with several laboratory yeast strains, to study potential relationship between ergosterol contents and vanillin tolerance. S. cerevisiae NBRC1950 was selected as a vanillin tolerant strain. Its ergosterol contents were higher than those of laboratory strains. The results of DNA microarray and quantitative RT-PCR analysis showed that 5 genes involved in ergosterol biosynthesis (ERG28, HMG1, MCR1, ERG5 and ERG7) were up-regulated in NBRC 1950 compared with strain X2180, suggested that high expressions of genes involved in ergosterol biosynthesis may cause for the high ergosterol content in strain NBRC 1950. more...

(Submitter supplied) A six array study using total gDNA recovered from two separate cultures of each of three different strains of Saccharomyces cerevisiae (YB-210 or CRB, Y389 or MUSH, and Y2209 or LEP) and two separate cultures of Saccharomyces cerevisiae DBY8268. Each array measures the hybridization of probes tiled across the Saccharomyces cerevisiae genome.

(Submitter supplied) Xylose-utilizing yeasts with tolerances to fermentation inhibitors (such as weak organic acids) and high temperature are needed for cost-effective simultaneous saccharification and co-fermentation (SSCF) of lignocellulosic materials. We constructed a novel xylose-assimilating Saccharomyces cerevisiae strain with improved fermentation performance under heat and acid co-stress using the genome shuffling technique. more...

(Submitter supplied) In the search for renewable sources of energy, bioethanol stands out as a benchmark biofuel because its production is based on a proven technological platform. Bioethanol is produced mainly from the fermentation of carbohydrates derived from agricultural feedstocks by the yeast Saccharomyces cerevisiae. One of the most widely adopted strains is PE-2, a heterothallic diploid naturally adapted to the sugar cane fermentation process used in Brazil. more...

(Submitter supplied) The arrays in this series correspond to a comparative genomic analysis between S. cerevisiae strain JAY270 and the reference laboratory strain S288c. JAY270 is a heterothalic diploid used in bioethanol production from sugar cane feedstock in Brazil. This strain has several chromosomal length polymorphisms between homologous chromosomes. The two Chr6 homologs, Chr6 short and Chr6 long, were examined using microarrays to determine the genomic regions which are rearranged. more...
