The immobilized L-glutamic decarboxylase on the CM-CADB (carboxymethyl-copolymer of allyl dextran and N, N'-methylene-bisacrylamide) ion exchange resin has been studied in this paper.
Thickener was prepared by inverse emulsion polymerization of ammonium acrylate using an amphiphilic copolymer as steric stabilizer, Span 80 as emulsifier and methylene bisacrylamide as crosslinker.
