BIOCONVERSION OF CEPHALOSPORIN-G TO 7-AMINO DEACETOXY CEPHALOSPORANIC ACID

Cephalosporin-G (Ceph-G) was converted to 7-amino deacetoxycephalosporanic acid (7-ADCA) using immobilized penicillin-G acylase (ImPGA). Effect of different variables on the rate of hydrolysis using a recirculated packed bed reactor (RPBR) was studied. A comparison between a RPBR and a stirred tank reactor (STR) was carried out. The RPBR was found to be superior to STR.
