摘要： Materials and methods are described to produce xylitol from a mixture of hemicellulosic sugars by several routes. Examples include either as a direct co-product of a biorefinery or ethanol facility, or as a stand-alone product produced from an agricultural or forestry biomass feedstock including using, e.g. ethanol waste streams.

摘要： Engineered mutant xylose reductases demonstrate higher preference to xylose than arabinose. Amino acid mutations were engineered in to native xylose reductase from Neurospora crassa. Mutant xylose reductases are useful in the production of xylitol and ethanol.

摘要翻译： 工程化的突变木糖还原酶表现出比阿拉伯糖更优先于木糖。 将氨基酸突变工程改造为来自粗糙脉孢菌的天然木糖还原酶。 突变木糖还原酶可用于生产木糖醇和乙醇。
