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

Figure 1

Influence of replacement of glucose by starch on colistin production in P. polymyxa. (a) Colistin production along fermentation; (b) growth curve of P. polymyxa along fermentation; (c) rate of colistin biosynthesis along fermentation; (d) colistin production per cell biomass after 96 h 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.
