ENZYMATIC PREPARATIONS FROM Mucor MOULDS AND THEIR APPLICATION IN OLIGOAMINOSACCHARIDES PRODUCTION
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2009, Vol 0, Issue
Abstract
A method of chitosan hydrolysis catalyzed by intracellular chitosanolytic enzymes produced by strains of Mucor circinelloides and Mucor racemosus was developed within the scope of presented study. Hydrolysis of the biopolymer was carried out with the use of: I) mycelial preparation of chitosanolytic enzymes, II) preparation of partially purified enzymes and III) mycelium immobilized in a polyurethane carrier (used in the system of continuous hydrolysis of biopolymer). All these enzymatic preparations extremely effectively catalyzed hydrolysis of various chitosan preparations. They converted chitosan to products having different molecular weight, such as low-molecular weight chitosan, chitooligosaccharides and D-glucosamine. Furthermore, these preparations are relatively inexpensive and highly stable during long-term storage.
