Abstract
The expression at different temperatures of the lacZ gene, which is co ntrolled by the lambda p(L) and P(R) tandem promoters and the cI857 te mperature-sensitive repressor, was studied in Escherichia coli continu ous cultures. At temperatures between 30 and 42-degrees-C, beta-galact osidase activity behaved according to an exponential equation. By indu cing a culture at a temperature within this range, predefined, nearly constant submaximal levels of gene expression and recombinant product yield can be obtained.
