Recently bistability in the pyruvate production of ammonia‐limited glucose‐grown Escherichia coli ML 30 chemostat cultures was evidenced. The present investigation shows that the state of higher pyruvate production is connected with a lower glycogen content than in cells in the state of lower pyruvate production. The results support the view of a regulation of bistability on the step of pyruvate consumption by the citric acid cycle. Pronounced differences in energy formation in the two states of glucose bistability are discussed.
