Time course of cell dry weight (CDW) [g/L] (a) and surfactin concentration [mg/L] (b) of strains B. subtilis JABs24 (reference), MG12 (PnarG-lacZ; amyE::[PnarG-lacZ, spcR]) and MG14 (PsrfA::PnasD; amyE::[PnasD-lacZ, spcR]) cultivated in a mineral salt medium with 40 g/L glucose, 0.1 mol/L NH4+ and 0.1 mol/L NO3− employing three different relative filling volumes of 10%, 50 and 100% representing different oxygen availabilities
