title: Chitosan hydrolysis by immobilized chitosanases and non-specific enzymes
abstract: Chitooligosaccharides (COS) are products of the chitosan hydrolysis, which are high value-added because of their biological activities. The chitosan hydrolysis can be catalyzed by acid, although this method requires high temperature and does not have a large selectivity regarding the size of the COS chains, a key feature for the expression of biological activities. Alternatively, the use of enzymes as catalysts for the hydrolysis becomes an interesting option because it requires mild conditions
