Recent Trends in Production, Characterization, and Utilization of Fungal Chitosan
Abstract: Chitosan is the second most abundant biopolymer in nature after cellulose that can be extracted from marine sources, as well as from agricultural waste products such as mushrooms or other fungal sources following chitin deacetylation. The consistent production of these glycans by fungi is unaffected by seasonal changes, allowing for precise process control. This results in a more consistent quality of the final product. Currently, crustacean shells and other marine …
