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.
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.
