Fig. 5 Effects of medium components on the production of PCP vaccine proteins.
For the optimization of carbon source, the OD600 and protein yield under glucose carbon source were used as the control, defined as 1. For the optimization of nitrogen source, the OD600 and protein yield in the original TBSB medium were used as the control, defined as 1. (A) Effect of carbon source on Oml1 production. (B) Effect of carbon source on Oml7 production. (C) Effect of carbon source on ApxⅡ production. (D) Effect of nitrogen source on Oml1 production. (E) Effect of nitrogen source on Oml7 production. (F) Effect of nitrogen source on ApxⅡ production.
