  • Publication number: 20130266992
    Abstract: The present invention relates to a novel method for increasing saccharification efficiency by adding chaperone protein during saccharification process, more precisely a composition for increasing saccharification efficiency of biomass containing cellulose using peroxiredoxin (Prx) protein and a method for increasing glucose yield by using the same. The conventional saccharification process has the disadvantage of decreasing cellulase activity, suggesting that the high priced saccharogenic enzyme has to be continuously supplied since the saccharogenic enzyme is losing its activity continuously by reducing sugar through the whole saccharification process. Therefore, to increase saccharification efficiency, the present invention provides a method characterized by increasing saccharification efficiency by preventing cellulase from losing its activity throughout the whole saccharification process by using chaperone protein, particularly Prx protein herein, together with cellulase.

  • Patent number: 8524471
    Abstract: The invention concerns a method for the enzymatic treatment of raw polymeric feedstock comprising the following steps: (a) preferably separation of soluble components from the raw polymeric feedstock, (b) treating the raw polymeric feedstock with an enzyme system in order to liberate defined soluble monomeric or oligomeric building blocks from the insoluble raw polymeric feedstock; and (c) separating the defined monomeric or oligomeric building blocks produced in step b) from the remainder of the raw polymeric feedstock. Preferably, the enzyme system used in step b) contains not more than 50%, preferably not more than 20%, more preferably not more than 10%, more preferably not more than 5%, more preferably not more than 2%, more preferably not more than 1% of other enzyme activities apart from the enzyme activity resulting in liberation of said defined monomeric or oligomeric building blocks from the raw polymeric feedstock according to step b).

  • Publication number: 20130224805
    Abstract: A process and apparatus for converting cellulosic biomass pulp into a sugar solution is provided. The process includes combining a quantity of cellulosic biomass pulp with a quantity of acid and a quantity of enzyme. The combined quantity of cellulosic biomass pulp, enzyme, and acid are placed in an enzymatic hydrolysis reactor having a predetermined temperature range and predetermined pH level, thereby producing a quantity of monomeric sugar solution.

  • Patent number: 8518672
    Abstract: A method for the production of alcohol and other bioproducts hemicelluloses extracted from biomass prior to thermal conversion of the biomass to energy. The process can be integrated with the host plant process to minimize the energy loss from extracting hemicelluloses. Also disclosed is a Stepwise enzymatic break down of cellulose fibers from a pulping operation which is performed with the redeployment of equipment and vessels contained within typical existing pulp and paper manufacturing mills. The preferred feedstock is highly delignified pulp from acid or alkaline pulping process or from bleaching stage.

  • Publication number: 20130210089
    Abstract: The present invention concerns a process for the conversion of lignocellulosic biomass into sugars, comprising at least three steps. The first step is a step for cooking the lignocellulosic biomass in the presence of at least one hydrated inorganic salt mixed with at least one other metallic salt. The second step is a step for separating at least one solid fraction which has undergone the cooking step, and the third step is a step for enzymatic hydrolysis of said solid fraction to convert the polysaccharides into monosaccharides. The sugars obtained thereby can then be fermented into alcohols.
