Abstract:
The aim of this work was to optimizes a biorefinery process for the conversion of mixed hydrolyzates from agro-industrial by-products into high oleic Single Cell Oils (SCOs), a versatile platform for the production of many bio-based chemicals. In particular, the specific objective was to convert undetoxified wheat straw hydrolyzates in triglycerides by the oleaginous yeast Yarrowia lipolytica ATCC 46483. To this scope, the lignocellulosic biomass was fractionated by a steam-explosion process into its constitutive macromolecules, namely cellulose, hemicellulose and lignin. Process strategies were optimized to produce concentrated hydrolyzates containing both C6 and C5 sugars that were used as growth medium for the lipids production.
