Enzymatic Preparation of L-Glucose, L-Galactose and L-Xylose Using Galactose oxidase Immobilised on Crab-shell Particles

Abstract

Galactose oxidase has been immobilised on a solid support developed by modification and activation of surfaces of crab-shell particles. The conversion of D-sorbitol to L-glucose, galactitol to L-galactose and xylitol to L-xylose using the immobilised galactose oxidase have been demonstrated. The performance of the immobilised galactose oxidase for the conversion of D-sorbitol to L-glucose in a mini batch reactor has been studied. The advantages of this method for preparing L-sugars have been discussed.
