Rice hull hydrolysate was used as feedstock for microbial lipids production using the oleaginous fungus Mortierella isabellina. Kinetic experiments were conducted in C/N ratios 35, 44 and 57 and the oil accumulation into fungal biomass was 36%, 51.2% and 64.3%, respectively. A detailed mathematical model was used in order to describe the lipid accumulation process. This model was able to predict reducing sugar and nitrogen consumption, fat-free biomass synthesis and lipid accumulation. Neutral lipids constitute the predominant lipid fraction, while the major fatty acids were oleic, palmitic and linoleic acid. Fatty acids of long aliphatic chain were not detected, thus the microbial oil produced is a promising feedstock for biodiesel production.
米糠水解物被用作产油真菌玫红弯孢霉的生物量油脂生产的原料。在 C/N 比为 35、44 和 57 的情况下进行了动力学实验，油脂在真菌生物量中的积累分别为 36%、51.2%和 64.3%。详细的数学模型用于描述油脂积累过程。该模型能够预测还原糖和氮的消耗、无脂生物量的合成和油脂的积累。中性脂质构成了主要的脂质部分，而主要的脂肪酸是油酸、棕榈酸和亚油酸。没有检测到长链脂肪酸，因此所生产的微生物油是生物柴油生产有前途的原料。
