  1. C. freyschussii ATCC 18737 was cultured in GMY medium containing 3 g/L yeast extract and different glycerol concentration, in order to obtained different C/N ratios. Biomass was harvested for lipid analysis at the latest after 72 h, unless glycerol was depleted earlier. Final fatty acids profile are reported. Values are means, n = 3, SD always < 3%. Within each column, means are significantly different (P < 0.05), unless they have a common letter.
