Compared with immobilized glucose oxidase, free glucose oxidase has the advantages like more stable, easy to control, can be used repeatedly, easy to recycle, low cost and etc., so it is widely used in the fields of chemistry, biology, biological engineering, medicine, life science and etc.. The effects of pH value, temperature and concentration of guanidine hydrochloride on the activity of immobilized glucose oxidase were studied, and the effects of reusing times and time on the stability of immobilized glucose oxidase were studied when microcapsule was prepared from immobilized glucose oxidase. Experimental results show that when pH value of immobilized glucose oxidase is 4 and temperature is 40 ℃, the relative activity of immobilized glucose oxidase is maximum; with the increasing of guanidine hydrochloride concentration, its relative activity is gradually decreased, but the decrease range is smaller than the free enzyme; when immobilized glucose oxidase is reused, its repetition rate is relatively stable; with time extending, the relative activity of immobilized glucose oxidase is gradually decreased, but the rate is lower than free enzyme.
