Abstract: | Chitinous material was isolated from the mycelium of seven species of Basidiomycetes to evaluate the possibility of using fungal biomass as a source of chitin and chitosan. Such material was characterised for its purity, degree of acetylation and crystallinity. Chitin yields ranged between 8.5 and 19.6% dry weight and the chitosan yield was approximately 1%. The characteristics of the fungal chitins were similar to those of commercial chitin. Chitosans, with a low degree of acetylation, comparable with that of commercial chitosan, were obtained by the chemical deacetylation of fungal chitins. |
