Abstract
Penicillin G-Acylase is produced by submerged cultivation of E. Coli (NCIM-2400) and extracted from the harvested fermented broth, purified (affinity chromatography) and immobilised on Eupergit C (Synthetic polymer in bead form). The immobilised penicillin G acylase properties are studied and compared with soluble penicillin G-acylase. The control parameters for conversion of penicillin G-K to 6 APA are optimised [e.g. substrate (Pen G-K) concentration ratio to immobilised penicillin G-acylase, temperature, pH etc.] in a stirred tank reactor. Our findings suggest that immobilised penicillin G-acylase can be used commercially and the productivity of 1 kg. of immobilised enzyme is around 400 kg of 6 APA under given desired stipulated conditions.
