Description: Microbial lipids have the potential as an alternative feedstock for biofuel production. The major problem is the cost of its production. Nevertheless, lipid production using lignocellulosic biomass residues from industries, domestic, agricultural, and forestry could be an economical option. The present study aims to evaluate the lipid production in R. toruloides-1588 using forestry residues (hardwood and softwood sawdust) as a carbon source. In undetoxified hydrolysate, maximum biomass observed was 17.09 and 19.56 g/L in hardwood and softwood derived hydrolysate, respectively. Maximum lipid was accumulated as 36.68% and 35.24% in both hydrolysates, respectively, which was 20% higher than from synthetic media. Despite the presence of inhibitors, R. toruloides-1588 was able to grow and accumulate lipid which reflects its tolerance towards inhibitors. Furthermore, the production of various polyunsaturated fatty acids was reported and described briefly.
