Effects of adding potassium dihydrogen phosphate to the initial medium on the fermentation process of ZL1004 strain. Mode 1: the concentration of potassium dihydrogen phosphate addition was 0.08 g/L. Mode 2: the concentration of potassium dihydrogen phosphate addition was 0.12 g/L. (A) Soluble phosphate. (B) Amino nitrogen. (C) Dissolved oxygen. (D) Erythromycin.
