Abstract

An extracellular chitosanase produced by Rhodotorula gracilis CFR-1 that catalyses a limited degradation of chitosan with no detectable generation of glucosamine or reducing groups was identified. Ultracentrifugation, PAGE and gel permeation studies suggest that chitosan of average molecular mass 36 000 Da was reduced by the enzymic catalysis to nearly 1/4 this size without further hydrolysis of the products. The enzyme, produced constitutively by this yeast, was partially purified and some of its properties were studied.
