Abstract
Official abstract text for this publication.
Systems and methods for producing levulinic acid from fungal biomass are disclosed. In one implementation, a method for distilling levulinic acid from a glucosamine-containing feedstock is disclosed that yields a relatively pure (e.g., 90% or greater) levulinic acid product from an otherwise problematic waste stream.
First claim
Opening claim text (preview).
We claim: 1. A method for producing levulinic acid, comprising: forming a glucosamine-containing feedstock comprising levulinic acid and at least 0.1 wt % glucosamine by providing a chitin-containing fungal biomass, treating the chitin-containing fungal biomass with an acid having a concentration from 5 to 25 weight percent under reflux conditions to provide a glucosamine composition, and extracting the glucosamine composition to provide crystallized glucosamine and a superna…
