Effects of furfural and acetic acid on growth and lipid production from glucose and xylose by Rhodotorula glutinis

摘要: Microbial conversion of lignocellulosic sugars to triacylglycerols (a biodiesel or renewable diesel feedstock) was investigated using the oleaginous yeast Rhodotorula glutinis (ATCC 15125). In shake flask experiments, R. first grown in a nitrogen-rich medium utilizing an artificial acid hydrolysate biomass switchgrass as sole carbon and energy source. Once culture had reached stationary phase, cells were harvested transferred fresh nitrogen-free media containing for lipid accumulation. Analysis data collected showed that able grow The net specific Growth rate(s) indicated presence acetic furfural inhibited growth on glucose, but not xylose. accumulated cells, determined by gravimetrical method, increased from initial 4.3%–39.0% dry cell mass weight. major fatty acids lipids palmitic acid, stearic oleic linoleic γ-linoleic acid. These results indicate it is feasible convert glutinis.
