Abstract
The invention describes optimised fermentation processes for the production of foreign proteins in E.coli using the lac promoter or improved lac promoter (e.g. tac, trc). After the initial growth phase with glucose as carbon source, product formation is induced (1) by IPTG with glucose limitation or (2) by lactose with lactose limitation or (3) by IPTG and lactose with lactose limitation. The limitation of glucose or lactose is such that the partial pressure of oxygen remains above 10%.
