Abstract
Described are novelstrains that were obtained by UV-C irradiation of wild-typeNRRL Y-7124 cultures, followed by 5-month anaerobic growth on xylose at 28° C. The UV-C-mutagenized strains were able to grow anaerobically on xylose or glucose medium with higher ethanol production than ayeast strain under comparable fermentation conditions. The mutagenized strains were identified by DNA fingerprinting to be unique strains closely related to wild-type. These mutagenized strains have potential application in large-scale industrial conversion of lignocellulosic sugars to fuel ethanol.
