Co-production of microbial oil and exopolysaccharide by the oleaginous yeast Sporidiobolus pararoseus grown in fed-batch culture.

ABSTRACT: The production cost of microbial oil was reduced by improving the exopolysaccharide (EPS) production to share the production cost using Sporidiobolus pararoseus JD-2. Batch fermentation demonstrated that S. pararoseus JD-2 has the potential to co-produce oil and EPS with 120 g L^-1 glucose, 20 g L^-1 corn steep liquor and 10 g L^-1 yeast extract as carbon and nitrogen sources. Using fed-batch fermentation for 72 h resulted in oil and EPS production of 41.6 ± 2.5 g L^-1 and 13.1 ± 0.6 g L^-1 with the productivity of 0.58 g L^-1 h^-1 and 0.182 g L^-1 h^-1, respectively. The fat soluble nutrients in the oil were studied, indicating that it was constituted of 79.19% unsaturated fatty acids a
