Screening of Fungi for Microbial Oil Production Using N-Acetyl-D-glucosamine
转化N-乙酰-D-葡糖胺产油真菌的筛选

Preliminary screening study on 21 fungi strains were carried out to identify those capable of producing lipids using N-acetyl-D-glucosamine (NAG) as carbon source. It was found that 7 strains can assimilate NAG effectively, and 3 of them can accumulate substantial amount of lipids. Under shaking flask culture conditions, cellular lipid content for C. albidus ATCC 56298 and T. fermentans CICC 1368 reached 67% and 48%, respectively. Gas chromatography analysis indicated that compositional fatty acids of these microbial lipid samples contained mainly palmic acid, stearic acid and oleic acid, closely resembling those of vegetable oil. This work further extends feedstock options for microbial lipid fermentation and provides new ideas for exploration of chitin and related renewable materials.
