Abstract:
1. A method of obtaining glucosamine from fungal biomass, the method comprising: producing a commercial-scale amount of glucosamine suitable for animal and/or human consumption, from fungal biomass through (a) providing a chitin-containing fungal biomass, which fungal biomass has not been pretreated to release proteins, lipids and/or polysaccharides therein; (b) reacting the non-pretreated fungal biomass in an acidic solution comprising HCI at a concentration of at least 5%, at a reaction temperature of from about 90° C. to about 160° C. and for a period of time sufficient for said reaction to convert at least about 50% of the chitin in the fungal biomass to glucosamine; and (c) separating the glucosamine from the acidic solution.
