Fig. 1From: Continuous enhancement of iturin A production by Bacillus subtilis with a stepwise two-stage glucose feeding strategyTime courses of reducing sugar and iturin A concentrations (a) and number of total cells and number of spores (b) using rapeseed meal as nitrogen sources in flask batch fermentation. Symbols: iturin A concentration (●), reducing sugar concentration (▲), number of total cells (■), number of spores (□). Each point represents the mean (n = 3) ± standard deviationBack to article page
