A fungus strain producing microbial oils utilizing pretreated rice straw was isolated from soil. This strain was identified as Mortierella elongata PFY based on the morphology and internal transcribed spacer sequence. Using pretreated rice straw as substrate, the average yield of total lipids was 7.07% after 7 days fermentation. The GC-MS detection demonstrated that the lipids were composed of saturated fatty acids and polyunsaturated fatty acids. This work presents one new way to make the waste biomass (rice straw) valuable.
从土壤中分离出一株利用预处理稻秸生产微生物油脂的真菌菌株。该菌株根据形态学和内部转录间隔区序列被鉴定为长枝木霉 PFY。以预处理稻秸为底物，发酵 7 天后，总油脂的平均产率为 7.07%。GC-MS 检测表明，油脂由饱和脂肪酸和多不饱和脂肪酸组成。这项工作为利用废弃生物质（稻秸）提供了一种新方法。
