  • Patent number: 8679795
    Abstract: The present invention relates to polypeptides having xylanase activity and nucleic acid sequences encoding such polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid constructs as well as methods for producing and using the polypeptides. One specific application of the xylanase is the selective hydrolysis of pentose sugar components of hemicellulose-containing plant biomass. The nucleotide sequence may be used for the production of the xylanase or optimized mutants thereof.

  • Publication number: 20140045227
    Abstract: The present invention provides a process for degradation of lignocellulosic biomass, which has optionally been pre-treated. It is based on the finding that hydrolysis efficiency of the biomass is enhanced in the presence of a mechanically or chemically treated microorganism capable of producing the respective hydrolytic enzymes. The invention therefore provides a process for degradation of lignocellulosic biomass with integrated produced enzyme cocktails. The invention also provides a process wherein the part of the optionally pre-treated lignocellulosic biomass is incorporated into the final growth medium of the fungus.

  • 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).
