Cultivation of oleaginous yeast using aqueous fractions derived from hydrothermal pretreatments of biomass.

摘要: This study addresses some of the current challenges in producing biofuels from yeast oils. Specifically, it valorizes byproduct waste streams biomass processing technologies by integrating them as alternative carbon or nutrient sources oleaginous cultivation. Crude glycerol recovered thermal hydrolysis various fats and oils was successfully used culturing Cryptococcus curvatus, with growth lipid accumulation occurring at levels identical to those achieved when commercially purchased used. The aqueous stream hydrothermal C. curvatus can also be recycled a substrate for subsequent cultures. addition this promoted higher production without affecting only moderately changing fatty acid profile. Use these recycling strategies reduces costs environmental impact microbial providing accessible, non-expensive nutrients
