The possibility of using the multicompartment immobilized enzyme reactor (MIER) in presence of a charged substrate is here explored. Penicillin G acylase is used to convert penicillin G (a free acid, with a pK of 2.6) into two charged products: phenyl acetic acid (PAA, with a pK of 4.2) and 6-aminop

## Abstract The kinetic parameters for penicillin G hydrolysis in systems with penicillin G acylase from __Escherichia coli__ (free and immobilized on activated chitosan microbeads produced by electrostatic extrusion) were determined. The obtained kinetic results indicated that both systems (free a
