Abstract Over-expression of Proteus vulgaris K80 lipase gene in Escherichia coli BL21 (DE3)/pKLE was achieved, with the enzyme being produced in an as active soluble form, using the T7 RNA polymerase system in a modified M9 salt or M9ZB medium. d-Lactose (55 mM) was used to induce gene expression and gave twice the lipase activity achieved with 0.4 mM IPTG. The expression of the lipase gene depended on the feeding rate of glucose being optimal at 12 g l−1 h−1.
