木糖是红橡木预水解产物中的主要糖，由树干毕赤酵母CBS 5776发酵成乙醇。有毒的模型化合物来自红橡木半纤维素，木质素，和提取物抑制发酵。用分子筛和混合床离子树脂处理预水解产物有利于乙醇发酵，从32 g/l初始木糖得到约10 g/l乙醇。对红橡木木质素和抽提物中的发酵抑制剂进行了鉴定。
Xylose, the predominant sugar in red oak prehydrolysate, is fermented to ethanol by Pichia stipitis CBS 5776. Toxic model compounds derived from red oak hemicelluloses, lignin, and extractives inhibited the fermentation. Treatment of the prehydrolysate with molecular sieve and mixed bed ion resins facilitated the ethanol fermentation giving about 10 g/l ethanol from 32 g/l initial xylose. Fermentation inhibitors derived from red oak lignin and extractives were identified.
