Abstract
The biopolymer chitosan possesses bioactive properties that have potential application in wound-healing. Chitosan is commercially obtained by the chemical modification of crustacean chitin that has been extracted from prawn- and crab-shell wastes. However, fungal chitosan provides a continuous source of chitosan with more consistent properties than the crustacean chitosan. Fungal chitosan was prepared, isolated, and characterised. Its bioactivity and, in particular, its macrophage activation and fibroblast proliferation were investigated.
