The pyruvate production of E. coli ML 30 in continuous cultures was investigated. In a glucose mineralsalt medium with ammonium as the limiting substrate two stable stationary states (bistability) of pyruvate concentration were obtained. The bistability was limited to dilution rates lower than 0.3 h −1 and connected with a decrease of the yield coefficient ( Y Glc ) from ≈0.45 to ≈0.1.
