Fermentation optimization of strain C-E277K. (A) Impact of varying inoculations on production by C. glutamicum C-E277K during fermentation. Impact of varying shaker speed on production by C. glutamicum C-E277K during fermentation. Impact of varying liquid loading on production by C. glutamicum C-E277K during fermentation. (B) Influence of different concentration medium on l-serine titer of C. glutamicum C-E277K during fermentation (Control: Gray, group 1–20: purple, group 21–23: orange, group 24–28: green). (C) Fermentation results for the strain C-E277K under optimal conditions in a 5-L bioreactor. The cell growth (blue), l-serine titer (red), and residual sucrose (black) of strain C-E277K are presented.
