The strain was cultured at different temperatures in GMY medium containing 40 g L^-1 glucose, as described in Methods section. The final concentration of biomass and lipids, the specific growth rate (μ), the biomass/glucose, lipid/glucose, and lipid/biomass yield coefficients (Y_X/S, Y_L/S, and Y_L/X, respectively), and the volumetric productivities of biomass and lipids (Q_X and Q_L, respectively) are reported as a function of the growth temperature. The values are means of three independent experiments. Within a column, superscripts indicate statistically similar means, P > 0.05, n = 3.
