| titleOfInvention | Method for immobilizing beta-glucosidase and hydrolyzing straw cellulose by cooperating beta-glucosidase with cellulase |
| abstract | The invention relates to a method for immobilizing beta-glucosidase and hydrolyzing straw cellulose by cooperating the beta-glucosidase with cellulase, belonging to the technical field of biocatalysis. The method provided by the invention comprises the following steps of: (1) dissolving chitosan into a propionic acid solution to form a transparent and homogeneous colloid, mixing and stirring the colloid with Fe3O4 grains, dropwise adding a NaOH solution to obtain magnetic microspheres, and carrying out crosslinking on the magnetic microspheres in a glutaraldehyde solution to obtain an immobilized carrier; (2) adding the immobilized carrier into a beta-glucosidase solution for adsorption to obtain a magnetic immobilized beta-glucosidase, hydrolyzing a cellobiose substrate by using the magnetic immobilized beta-glucosidase, and measuring the enzyme activity of the magnetic immobilized beta-glucosidase; and (3) degrading maize straws by coordinating the magnetic immobilized beta-glucosidase with the cellulase. The immobilized beta-glucosidase prepared by the method has the characteristics of homogeneous shape, large specific surface area, high mechanical strength, high enzyme activity and easiness in recovery; and the immobilized beta-glucosidase can hydrolyze the straw cellulose by coordinating with the cellulase to increase the yield of hydrolyzed sugar, and the stability in repeated use is good, so that the cost for the enzymatic hydrolysis of the straw cellulose can be lowered. |
