Maximal biotransformation and production of C-K from PPD-type ginsenosides in AGE in fed-batch fermentation of A. tubingensis. A Maximal biotransformation of C-K from PPD-type ginsenosides in 8 g/L AGE. B Concentration change of PPD-type ginsenosides in 8 g/L AGE during C-K production. AGE at 8 g/L was continuously added from 12 to 84 h at a flow rate of 0.11 g/L/h. C Maximal production of C-K from PPD-type ginsenosides in 20 g/L AGE. D Concentration change of PPD-type ginsenosides in 20 g/L AGE during C-K production. AGE at 20 g/L was continuously added from 12 to 84 h at a flow rate of 0.28 g/L/h. Sucrose at 20 g/L was initially added, and 40 g/L sucrose was then 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
