用里氏木霉纤维素酶水解玉米芯，并将其用作产油酵母毛孢酵母的生长底物，而不需要解毒或添加氮源或微量元素。培养7 d后，总生物量为24.4g/L，油脂含量为40.1%，油脂得率为9.8g/L，油脂系数（单位质量糖的油脂得率，% g/g）为16.7。因此，T. Dermatum是一种很有前途的从木质纤维素生物质生产微生物油脂的菌株。(C)2012爱思唯尔有限公司保留所有权利。
Corncob was hydrolyzed with Trichoderma reesei cellulase and used as substrate for growth by the oleaginous yeast Trichosporon dermatis without detoxification or addition of a nitrogen source or trace elements. A total biomass of 24.4 g/L with a lipid content of 40.1% (corresponding to a lipid yield of 9.8 g/L), and a high lipid coefficient (lipid yield per mass of sugar, % g/g) of 16.7 could be achieved after cultivation for 7 days. Therefore, T. dermatis is a promising strain for microbial oil production from lignocellulosic biomass. (C) 2012 Elsevier Ltd. All rights reserved.
