PRODUCTION OF CHITOSAN OLIGOSACCHARIDE DERIVED FROM MICROORGANISM

摘要

PURPOSE:To efficiently produce a chitosan oligosaccharide derived from a microorganism, especially the chitosan oligosaccharide having a high degree of polymerization of pentamer or a high polymer from a hypha of a microorganism capable of producing chitosan according to a simplified process. CONSTITUTION:The characteristic of this method for producing a chitosan oligosaccharide derived from a microorganism comprises treating a hyphal cell wall of a microorganism capable of producing chitosan such as Absidia coerulea IFO5301 strain or Mucor tuberculisporus IFO9256 strain with an enzyme capable of producing the chitosan oligosaccharide such as Chitosanase RD<(>R<)> derived from Bacillus sp. PI-7S or Cellulase onozuka R-10<(>R<)> derived from Trichoderma viride.
