Effects of different mass fractions of carbon sources on yeast.
A Impact on biomass, B impact on lipid production, C impact on sugar consumption, D impact on lipid yield. The experimental data is measured at the 96th h of culture. Data are presented as the average of three independent experiments. Error bars represent means ± standard deviation. Significant differences were calculated using the t test (**p < 0.01, *p < 0.05)
