A galactose biosensor was developed by immobilizing galactose oxidase in a polyvinyl formal membrane and attached to the oxygen electrode of a dissolved oxygen analyzer for estimation of galactose in milk and milk products. The immobilized enzyme membrane was characterized by atomic force microscopy. The biosensor showed the linearity for 0.5-3.0 g dl(-1) galactose. The effects of PH and temperature and the stability of the immobilized galactose oxidase membrane were also studied. The enzyme membrane was found stable at temperatures up to 35 degrees C and had a shelf life of more than 90 days. (c) 2005 Elsevier B.V. All rights reserved.
