Effects of feeding-start and feeding-stop time points during continuous feeding of AGE on C-K production in fed-batch fermentation of A. tubingensis. A Effect of feeding-start time of AGE on C-K production. Feeding of AGE was stopped at 132 h. B Effect of feeding-stop time of AGE on C-K production. Feeding of AGE was started at 12 h. AGE at 16 g/L was continuously added. Sucrose at 20 g/L was initially added, and 40 g/L sucrose was continuously added from 12 to 132 h at a flow rate of 0.33 g/L/h. Black and red arrows indicate the feeding-start and feeding-stop time points of AGE, respectively
