FIG 2.

Batch fermentation of strain YIGS16 and the control strain AACK. (a) The final biomass, secreted amylase titer, and secreted amylase yield in batch fermentation. (b) The time course of the biomass and secreted amylase titer. (c) The time course of glucose consumption and ethanol and glycerol production. (d) The intracellular α-amylase amount and the intracellular percentages (calculated by dividing the intracellular α-amylase amount by the total amount of α-amylase) at six different time points. *, P < 0.05; **, P < 0.01. Measurements are reported as the average values ± standard deviations from independent quadruplicates.
