摘要: High ethanol yield is a desired property of industrial yeast strains. A significant problem in fermentative conversion lignocellulosic materials to the formation furfural and hydroxymethylfurfural (HMF), which are formed during acid hydrolysis lignocellulose. Furfural has been known create strong inhibition metabolism yeast Saccharomyces cerevisiae. In this article, result random mutagenesis native strain of S. cerevisiae by ultra violet (UV) light nitrous presented. By screening cells presence furfural, potent mutant was selected produced 36.7% more bioethanol than parent strain, 0.2% (v/v) furfural. Key words: Bioethanol, mutation, acid, Saccharomyces cerevisiae PTCC 5315, UV radiation.
