Title:
PRODUCTION OF CHITOSAN OLIGOSACCHARIDE
Document Type and Number:
Japanese Patent JPS6230103
Kind Code:
A
Abstract:
PURPOSE: To produce a chitosan oligosaccharide containing no monosaccharide of D-glucosamine in high yield inexpensively, by decomposing chitosan with chitosanase produced by a microorganism.
CONSTITUTION: A chitosan (e.g., colloidal chitosan, etc.,) is decomposed with chitosanase, an enzyme produced from a bacterium [e.g., Bacillus No7-M(FERM P-8139), etc.,], stable at 5W11pH, to give a chitosan oligosaccharide containing mainly an oligosaccharide with 2W8 polymerization degree without a D- glucosamine monomer.
USE: Useful as a food additive, a cosmetic component, a drug or a medical material.
