Batch cultivation using the optimized synthetic media formulation:
(a) () pO2 (%); (-) stirrer (rpm); (b) (•) optical density at 595 nm; () pH;
() glucose concentration (g∙L−1); () nitrogen concentration (mg∙L−1); (c)
() vegetative cell concentration (cells/mL); () spore concentration (spores/
mL). Error bars represent standard deviations.
