Reaction pattern of Bacillus cereus D-11 chitosanase on chitooligosaccharide alcohols.

abstract：:Many bacteria metabolize aromatic compounds via catechol as a catabolic intermediate, and possess multiple genes or clusters encoding catechol-cleavage enzymes. The presence of multiple isozyme-encoding genes is a widespread phenomenon that seems to give the carrying strains a selective advantage in the natural enviro...
