## Abstract The effects of organic cosolvents on the synthesis of ampicillin from phenylglycine methyl ester (PGME) and 6โamino penicillanic acid (6โAPA) using immobilized __Bacillus megaterium__ penicillin G acylase have been examined. Several cosolvents were tested for their influence on the enzy

Amino acids altered the production and activities of cephalosporin C acylase and penicillin V acylase from Aeromonas species ACY 95 to a varying degree. DL-Tryptophan enhanced the cephalosporin C acylase formation by 222% while suppressed the penicillin V acylase formation by 68%. Cephalosporin C a
The stabilisation of Escherichia coli penicillin G acylase (PGA) by dextran polymers (of molecular weight 11.5, 37.7 and 71 kDa) was studied. The inactivation of both the native and dextrancontaining enzyme preparations obeyed ยฎrst-order kinetics at the temperature and pH values studied. The optimal
