Application of novel electrospun nanofibrous membranes with different modifications for immobilising glutamine synthetase

Abstract

A novel method has been established in this study for the immobilisation of GS in electrospun nanofibrous membranes. Carbon nanotubes and glutaraldehyde enhanced the immobilisation, while collagen or peptide inclusion could recover the activity loss caused by glutaraldehyde. The obtained immobilised enzyme achieved high reusability and storage stability.
