| Abstract |
Soybean hulls are lignocellulosic residues generated in the industrial processing of soybean, representing about 5 % of the mass of the whole bean. This by-product is an important source of polymers such as cellulose (34 %) and hemicellulose (11 %), which could be valorized via biotechnology to improve the economic return of the oilseed chain. In the present work, soybean hulls were evaluated as a carbon source for biolipid production by Lipomyces starkeyi LPB 53. Initially the hulls were treated physicochemically and enzymatically to obtain fermentable sugars. Subsequently, biomass growth was evaluated using different nitrogen sources and the lipid production was optimized, reaching a maximum cell biomass concentration of 26.5 g/L with 42.5 % of lipids. Around 65 % of the xylose content was consumed. The obtained oil was majorly composed of oleic, palmitic, palmitoleic, linoleic and stearic fatty acids in a proportion of 54 %, 32 %, 4 %, 3 % and 2 %, respectively. |
