Fig. 4From: Evaluating the effects of biocompatible cholinium ionic liquids on microbial lipid production by Trichosporon fermentans Effect of C/N ratio on the lipid production by T. fermentans in the presence of [Ch][Lys] or [Ch][Ser]. a Cell growth of T. fermentans in the medium containing 30 mM lysine or serine as sole nitrogen source. b Cell growth and lipid accumulation of T. fermentans in the media containing 30 mM [Ch][Lys] or [Ch][Ser] but with different C/N ratios. The results are mean of two experiments, and error bars represent standard deviations from mean value.Back to article page
