Characterization and functional analysis of the MAL and MPH loci for maltose utilization in some ale and lager yeast strains

Article Abstract:

Maltose transport kinetics with the genotypes of some ale and lager yeasts are correlated and the MAL and MPH loci for maltose utilization in some ale and lager yeast strains are characterized. The results show that in some brewer's yeast strains some of the apparently multiple maltose transporter genes do not code functional transporters, which accounts for some marked differences between strains in alpha-glucoside transport and wort fermentation.

Engineering redox cofactor regeneration for improved pentose fermentation in Saccharomyces cerevisiae

Article Abstract:

Genetic engineering approach is employed to transform redox reactions of yeast to produce mainly ethanol from D-xylose. Research demonstrates the expression of NADP-GAPDH in Saccharomyces cerevisiae strain that contains the D-xylose pathway and deletion of the gene responsible for pentose phosphate pathway. The engineered strain ferments D-xylose to ethanol at a higher rate and yield.
