Abstract
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.
