摘要: Glutaraldehyde crosslinked chitosan - silica nanobeads have been used as a support in the immobiliza-tion process of pepsin. The effect pH, pepsin concentration, and temperature on characteristics both free immobilized had investigated this study. results showed that im-mobilized has wider pH range, better capacity, performance stability to high temperatures compared with those can be for 8 10 times at which activity remains 20%, whereas only once. These suggested promis-ing applications enzyme biocatalyst. © 2014 BCREC UNDIP. All rights reserved.
