    摘要: The present invention relates to methods of reducing the toxicity of lignocellulosic hydrolysates which comprise one or more inhibitors. One method reduces the amount of furfural inhibitor leading to a more effective process. Another method reduces the amount of xylitol produced during the fermentation of xylose present in lignocellulosic hydrolysates. Naturally occurring aldo/keto reductase enzymes, as well as, enzymes produced by recombinant cells or by selective adaptation may be employed.

    摘要: The present invention relates to methods of obtaining Z. mobilis mutant strains that are more tolerant to one or more inhibitors or more capable of efficiently fermenting one or more carbohydrates. Such inhibitors include ethanol, aliphatic acids, such as acetic acid, formic acid; furan derivatives, such as 2-furaldehyde, 2-furoic acid; and phenolic compounds, such as vanillin and hydroxybenzoic acid. Such carbohydrates may include xylose, arabinose, mannose and mixtures thereof. These mutant strains may be employed to, for example, effectively and efficiently prepare ethanol from biomass.
