Abstract

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.

The approximative estimation of the function μ([NH^+^~4~]) in cultures of __E. coli__ ML 30 had shown that bistability of the ammonium concentration in ammonium limited continuous cultures could be possible (BERGTER __et al.__ 1977).
