Article

Summary

The yeastZygosaccharomyces rouxii ATCC 12572 was selected for its ability to produce appreciable levels of ethanol and of various polyols from concentrated glucose media (20 %, w/v).Z. rouxii was shown to yield large quantities of glycerol and of the mixture arabitol + mannitol. Good agitation combined with appropriate aeration (1 vvm) allowedZ. rouxii to utilize glucose readily leading to high polyol production. Depending on the fermentation conditions used,Z. rouxii ATCC 12572 will give either ethanol or various polyols as main fermentation product(s).
