Synthesize immobilized penicillin acylase
WebABSTRACT: Penicillin G acylase immobilized on to iron oxide nano particle coated with polyethyleneimine was used to synthesize b-lactam antibiotic namely ampicillin through kinetically controlled process. 6-Aminopenicillanic acid (6-APA) and R- phenylglycine methyl ester (PGME) were employed at different molar ratios to synthesis ampicillin batchwise. http://scientiairanica.sharif.edu/article_3298_b8985c8965897b9846be7415c53bd35a.pdf
