[Biomass carbohydrates assimilation and lipid accumulation by Mortierella isabellina].
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.
