Polyploid fragile strains of Saccharomyces cerevisiae--a novel source of proteins for nutritional purposes.


A series of prototrophic fragile strains of different ploidy (2n, 3n and 4n) has been genetically constructed on the basis of haploid srb1 containing segregants of the fragile Saccharomyces cerevisiae mutant VY 1160. The strains have been characterized by several criteria. In regard to generation time, biomass yield, and nucleic acids content of the cells… (More)
