Abstract:
The penicillin G amidase (PGA) from Alcaligenes faecalis, which has interesting properties for use in combinatorial biochemistry, was produced by recombinant expression in Escherichia coli. The corresponding gene was cloned into a multicopy vector under the strict regulatory control of the rhamnose inducible promoter. Cells were grown in a synthetic minimal medium in a bioreactor (5 l working vol.), and production of PGA was induced by repeated addition of the inducer rhamnose, that served also as a carbon source. The fermentation yield was about 4500 units PGA activity per liter of culture medium.
