Fig. 2From: Continuous enhancement of iturin A production by Bacillus subtilis with a stepwise two-stage glucose feeding strategyThe relationship of spores to total cells ratios and starting feeding time (a), time courses of iturin A concentration (b) and reducing sugar concentration (c) in flasks using a pulsed glucose-feeding strategy with different feeding initiating times. Symbols: control (■), feeding at 24 h (○), feeding at 36 h (△), feeding at 48 h (□), feeding at 60 h (▽). Each point represents the mean (n = 3) ± standard deviationBack to article page
