Novel chitosan membranes as support for lipases immobilization: Characterization aspects
摘要：
Membranes of chitosan (QS), chitosan treated with glutaraldehyde (QGA) and chitosan crown ether (QCE) were utilized as carriers for immobilization of s.s. for QCE membranes. Elemental analysis and Raman spectra measurements of the lipase, supports and immobilized lipase systems gave evidence of the presence of enzymes on supports. Chitosan supports with internal surface area (m2g) among 3.31 and 1.26 were obtained. Regardless of these low values, acceptable protein load (0.61 to 3.21%) and esterification initial rates were achieved (0.88–2.75mmolming of protein).
