A cheap and non-toxic synthetic polymer, polyvinyl alcohol (PVA) has been used for enzyme immobilization. In this study immobilization of xylanase in PVA–alginate beads were developed and treated with sodium sulfate which prevented agglomeration and produced beads of high gel strength and conferred enzyme protection from inactivation by boric acid. Further immobilized Xylanase was characterized with respect to pH, temperature, incubation time and substrate concentration and compared with free Xylanase. The immobilized Xylanase activity was found to be lower than the free Xylanase activity. The activity was found to be highest at pH of 6, temperature of 55oC, incubation time of 40 min and substrate concentration of 1.1mg/ml.
