Abstract
This study aimed to select yeast strains from the Agricultural Microbiology Culture Collection (CCMA) to produce lipids and/or carotenoids using crude glycerol and sugarcane molasses as alternative carbon sources. Among the selected strains, nine exhibited oleaginous characteristics, with Torulaspora maleeae (CCMA 0039) reaching the highest accumulation of lipid content (77.7%) in the glucose medium. Notably, the Exophiala spinifera (CCMA, 2073) strain exhibited 35% lipid accumulation in glycerol pure. Furthermore, Rhodotorula dairenensis (CCMA 945), Rhodotorula mucilaginosa (CCMA 0156), Rhodosporidium toruloides (CCMA, 2032) and Cystofilobasidium ferigula (CCMA 1623) were identified as carotenogenic. Crude glycerol has proven to be the most effective medium for lipogenesis and carotenogenesis, also expressing diversity in fatty acid profiles, with C. ferigula demonstrating promise in the coproduction of lipids and carotenoids, achieving 41.88% lipid accumulation and 2.76 μg/mL of total carotenoids. These findings highlight the potential for utilizing industrial by-products for the sustainable production of important metabolites, paving the way for their integration into industrial bioprocesses.
