Abstract
Systems and methods are disclosed for treating lignocellulosic biomass to be supplied to a fermentation system for production of a fermentation product. The systems and methods comprise pre-treating the biomass into pre-treated biomass and separating the pre-treated biomass into a liquid component comprising sugars and a solids component comprising cellulose and lignin. The systems and methods also comprise treating the solids component of the pre-treated biomass into a treated component. The biomass comprises lignocellulosic material. Treating the solids component comprises application of an enzyme formulation and makeup water to form a slurry. The enzyme formulation comprises a cellulase enzyme. The makeup water includes a clarified thin stillage composition and/or an anaerobic membrane digester effluent composition.
