Abstract

In the usually diploid zygosaccharomyces bailii, treatment with benomyl and selection on canavanine media yields haploid strains from which recessive mutants can be isolated.

2. Transport of acetic acid in Zygosaccharomyces bailii: effects of ethanol and their implications on the resistance of the yeast to acidic environments

Author

Abstract

Ethanol suppresses the transport and accumulation of acetic acid in cells of Zygosaccharomyces bailii. This protects the cells from the possible negative effects of acetic acid. Ethanol controls the acid concentration inside the cell and keeps it below toxic levels. The acid enters the cell through a transporter protein by diffusion. The mechanism of ethanol-induced transport suppression enables Z. bailii to tolerate environments containing fermentation end products.
