To produce microbial lipids for biofuel production, carbohydrates and related compounds from biomass have been routinely utilized, yet amino acids (AA) from protein-rich wastes have been overlooked so far. We use the oleaginous yeast Cryptococcus curvatus ATCC 20509 as a lipid producer and evaluate the capacity for lipid production on proteinogenic AA individually or in designated blends under two-staged culture conditions. It was found that cellular lipid contents reached 48.8%, 44.5% and 29.0% when yeast cells were cultivated in media-contained AA blends with compositional profiles similar to those of sheep viscera, meat industry by-products and fish muscle, respectively, and that lipid coefficients were more than 0.10 g g(-1). Furthermore, cellular lipid contents were higher than 20% when most AA were used individually. High lipid coefficients of over 0.23 g g(-1) were observed when Pro, Trp or Leu were used as a substrate. Results also indicated that higher initial media pH or reduced phosphate concentration was beneficial for lipid production on AA. This work demonstrated the potential to use AA and related wastes as substrates for microbial lipid production by the yeast C. curvatus, which fit well with the protein-based biorefinery concept. Further efforts should be devoted to recognizing the metabolic features, identifying more robust lipid producer and optimizing lipid production processes.
