Lactose utilization in cheese whey by different transformant yeast strains and different ploidy of prototrophic hybrids


, : Lactose utilization in cheese whey by different transformant yeast strains and different ploidy of prototrophic hybrids. Annals of Agricultural Science Cairo 38(1): 367-375

This investigation utilized 9 strains of Saccharomyces cerevisiae with different ploidy, some of them including transformation with 40 kb of DNA, together with others transformed by a plasmid bearing the wild-type gene and others by LEU2 based on the vector YEP13. 18 ploidy of prototrophic hybrids and 2 strains of Schizosaccharomyces pombe were used to study their abilities to utilize lactose in whey and ferment wheat meal.

The efficiency of 7 strains of yeasts to ferment cheese whey into alcohol was studied using fresh whey (acidity less than or equal to 16 deg T) at 28-30 deg C for 48 h. The alcohol content in the whey fermented by the different strains ranged from...
