SPOUTED BED DRYING AS A METHOD FOR ENZYME IMMOBILIZATION

摘要：

　　Immobilization is usually a requirement to the use of enzymes as an industrial biocatalyst.In this work,endophytic fungus Cercospora kikuchii lipase was immobilized by covalent binding on agricultural by-products and microcrystalline cellulose.The enzyme-support system was dried in spouted bed.Microcrystalline cellulose with 1.5% of glutaraldehyde showed the best support,maintaining 179.1% of activity after drying,followed by the rice straw (173.9%),corn stover (169.8%),sugarcane bagasse (157.3%),green coconut fiber (102.3%) and corn cob (99.8%).The use of these immobilized derivatives obtained after spouted bed drying may help to increase the productivity while minimizing product recovery cost.
