The effects of various commercial and model surfactants of different structure and hydrophilicity were studied on water-in-oil (w/o) emulsion stability, potassium cation leakage and permeation of 6-nitro-3-phenylacetamide benzoic acid in a model system using Penicillin acylase (EC 3.5.1.11) immobilized in
A simple, rapid assay for screening penicillin G acylase-producing bacteria is presented. The method is based on the formation of yellow 2-nitro-5-aminobenzoic acid by penicillin G acylase acting on 2-nitro-5-phenylacetaminobenzoic acid (NIPAB). NIPAB test paper is briefly applied to bacterial
Preparation and general properties of crystalline penicillin acylase from Escherichia coli ATCC 11 105.
Immobilized Penicillin G Acylase (PGA) derivatives are biocatalysts that are industrially used for the hydrolysis of Penicillin G by fermentation and for the kinetically controlled synthesis of semi-synthetic beta-lactam antibiotics. One of the most used supports for immobilization is glyoxyl-activated
