Utilization of pentose sugars (D-xylose and L-arabinose) derived from hemicellulose is essential for the economic conversion of biomass to ethanol. Xylose-fermenting yeasts were discovered in the 1980s, but to date, no yeasts have been found that ferment L-arabinose to ethanol in significant quantities. We have screened 116 different yeasts for the ability to ferment L-arabinose and have found the following species able to ferment the sugar: Candida auringiensis, Candida succiphila, Ambrosiozyma monospora, and Candida sp. (YB-2248). Though these yeasts produced ethanol concentrations of 4.1 g/L or less, they are potential candidates for mutational enhancement of L-arabinose fermentation. These yeasts were also found to ferment D-xylose.
利用来自半纤维素的戊糖（D-木糖和L-阿拉伯糖）对于将生物质经济转化为乙醇至关重要。木糖发酵酵母于20世纪80年代被发现，但迄今为止，尚未发现能大量将L-阿拉伯糖发酵为乙醇的酵母。我们筛选了116种不同的酵母发酵L-阿拉伯糖的能力，发现以下几种酵母能够发酵这种糖：奥里金假丝酵母、嗜糖假丝酵母、单孢圆酵母和假丝酵母（YB-2248）。尽管这些酵母产生的乙醇浓度为4.1克/升或更低，但它们是通过突变提高L-阿拉伯糖发酵能力的潜在候选者。还发现这些酵母能发酵D-木糖。
