In a complex medium which supports fast growth rates, enzyme production occurred only when the growth rate declined, principally in the stationary phase. By contrast, in a synthetic culture medium with lactose as the carbon source supporting much lower growth rates, enzyme formation occurred simultaneously with cell growth. The repression of enzyme formation during rapid growth may be due either to catabolite repression or to the low level of mRNA synthesis concerned with the production of exoproteins.
