Production and conversion of chitosan with cultures of Mucor rouxii or Phycomyces blakesleeanus

Biotechnology Letters Aims and scope Submit manuscript

Summary

Highly deacetylated chitosan was accumulated in the mycelia ofMucor rouxii orPhycomyces blakesleeanus. These cultures also effected the deacetylation of the chitin ofAspergillus niger mycelium into chitosan. After 96 hours of incubation with these cultures the degree of acetylation of commercial crab shell chitosan was reduced from 25.0% to values between 4.3 and 8.6%. The potential exists for the production of chitosans with tailored physico-chemical properties from “waste” chitin.
