Biomass carbohydrates assimilation and lipid accumulation by Mortierella isabellina M2 strain were investigated. Corn fiber hydrolysate was specially studied. The results showed M. isabellina M2 strain achieved growth and lipid accumulation while glucose, xylose, mannose and arabinose were introduced as single carbon source, respectively. When M. isabellina M2 strain was cultivated on corn fiber hydrolysate with 6% sugars concentration, the biomass reached 18.2 g/L, the lipid content of dry mycelia was 45.7%, and the lipid yield achieved 8.3 g/L. It provided a promising perspective for microbial oils production with biomass hydrolysates.
研究了深黄被孢霉M2菌株对生物质碳水化合物的同化作用和脂质积累。特别研究了玉米纤维水解产物。结果表明,当分别以葡萄糖、木糖、甘露糖和阿拉伯糖作为单一碳源时,深黄被孢霉M2菌株实现了生长和脂质积累。当深黄被孢霉M2菌株在糖浓度为6%的玉米纤维水解产物上培养时,生物量达到18.2 g/L,干菌丝体的脂质含量为45.7%,脂质产量达到8.3 g/L。这为利用生物质水解产物生产微生物油脂提供了广阔的前景。
