Enhanced Production of Polymyxin E in Paenibacillus polymyxa by Replacement of Glucose by Starch

Figure 3

Influence of replacement of glucose by starch on residue reducing sugar (a) and pH (b) during fermentation. 45S: 45 g/L starch; 40S+5G: 40 g/L starch plus 5 g/L glucose; 30S+15G: 30 g/L starch plus 15 g/L glucose; 20S+25G: 20 g/L starch plus 25 g/L glucose; 45G: 45 g/L glucose. The statistically significant results are related to the condition of 45 g/L glucose.
