Metabolism

B. subtilis is a chemoheterotrophic organism. It uses glucose and ammonium/glutamine as preferred sources of carbon and nitrogen, respectively. The bacteria can grow on a minimal medium. It produces all cofactors.

A suite of models of B. subtilis metabolism can by found in SubtiPathways.
