  • Patent number: 9677059
    Abstract: The present invention relates to thermostable endoglucanases, particularly to proteins having endoglucanase activity which comprises an amino acid sequence having at least 96% identity to SEQ. ID NO.: 2, and proteins having endoglucanase activity which belongs to the GH7 class and which shows active thermostabilization.
    Type: Grant

  • Patent number: 9458443
    Abstract: The invention discloses cellulase enzymes with optimized properties for processing of cellulose- and lignocellulose-containing substrates. In particular, cellobiohydrolase enzymes with preferred characteristics are disclosed. The present invention provides fusion, insertion, deletion and/or substitution variants of such enzymes. Enzyme variants have enhanced thermostability, proteolytic stability, specific activity and/or stability at extreme pH. Nucleic acid molecules encoding said enzymes, a composition comprising said enzymes, a method for preparation, and the use for cellulose processing and/or for the production of biofuels are disclosed.
    Type: Grant

  • 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.
