Abstract: β-glucosidase extracted from almond was immobilized by adsorption on chitosan crosslinked with glutaraldehyde.The conditions of immobilization were achieved,when glutaraldehyde was oscillatetd and absorbed for 4 hours in the water bath:concentration 1.5 %,pH 5.5,and temperature 25 ℃.The results showed that,1 g chitosan adsorbs 5U β-glucosidase,and the rate of activity recovery is 27.34 %.
