Culture conditions as described in Fig. 2. Each experimental point is the mean value of at least two independent determinations. Letters refer to comparisons at vertical reading for each yeast species within the same group; numbers followed by different letters indicate statistically significant differences at p ≤ 0.05. The experimental data were treated according to Bonferroni post hoc test.
When maximum percentage of cellular lipids per dry cell mass was achieved.
