  1. The yeasts were cultured for 120 h in GMY medium containing 40 g/L glycerol. The amount of glycerol consumed during incubation, final biomass dry weight (DW) and lipids, and lipid/glycerol and lipid/biomass yield coefficients (YL/S and YL/X) are reported. Values are means, n = 3, relative SD always < 7%. Within each column, means are significantly different (P < 0.05), unless they have a common letter. n.g. indicates strains that did not grow.
