  • Publication number: 20140017736
    Abstract: A method of producing a sugar liquid includes hydrolyzing with a filamentous fungus-derived cellulase a product obtained by adding a water-soluble inorganic salt(s) to a pretreated product of cellulose to a final concentration of 5 to 35 g/L; and subjecting the hydrolysate to solid-liquid separation and filtering the obtained solution component through an ultrafiltration membrane to recover the filamentous fungus-derived cellulase as a non-permeate and to obtain a sugar liquid as a permeate.

  • Publication number: 20140017732
    Abstract: The present application describes a dilute two-loop method for treating biomass in the production of biofuels such as ethanol. The method involves washing the biomass to dissolve sugars that are associated with the biomass, and separating the washed biomass into a solids phase and a liquids phase. The solids phase is pretreated to render the biomass more susceptible to hydrolysis under conditions that do not produce substantial amounts of sugars. The pretreated biomass is separated into a second solids phase and second liquid phase, and the second solids phase is saccharified and fermented. The first and second liquid phases are recycled to dilute the biomass at various stages of the process.
