摘要
通过摇瓶发酵探讨了不同氮源对木霉产油脂的影响。并分别以汽爆秸秆、玉米秸秆,脱木质素的汽爆秸秆为固体培养基基质,用木霉进行发酵生产微生物油脂。结果表明,汽爆秸秆作为原料进行发酵所得油脂产量最高,绿色木霉的产油能力高于里氏木霉。经过6天的发酵培养,里氏木霉的油脂产量1.63 g/100 g干物料,绿色木霉油脂产量为1.83 g/100 g干物料。结果显示木霉能够直接降解木质纤维素类的作物秸秆并利用其积累油脂。
The effects of different nitrogen source on lipid production by Trichoderma strains though shaking culture was discussed. Solid state fermentation to produce lipid by trichoderma on lignocellulose which was steam exploded straw , corn straw or delignified steam exploded straw respectively were studied. The results show that, The highest lipid yield was obtained when the steam exploded straw was used as culture medium.The ability of accumulating microbial lipids of Trichoderma viride was better than that of Trichoderma reesei .After cultivation 6 days ,the lipid yield wasl.63 g/100 g dry material by Trichoderma reesei ,the lipid yield was 1.83 g/100 g dry material by Trichoderma viride. Results showed that trichoderma strains could produce and accumulate micriobial lipids by decomposing lignocellulosic materials.
