  • Fungal Cellulase Variants With Improved Stability
    Publication number: 20220002697
    Abstract: The invention relates to novel variants of fungal endoglucanases. The invention further relates to enzyme preparations and detergent compositions comprising the variant as well as to processes for treating cellulosic material with the variant. The variants have depilling, antipilling and/or antigreying performance, and improved stability in the presence of proteases.
    Type: Application

  • Variants of fungal cellulase
    Patent number: 10570383
    Abstract: The present invention relates to polypeptides having cellulase activity, in particular to variants derived from the 20K-cellulase enzyme. The invention discloses a number of amino acid residue positions important for the properties of the cellulase enzyme and thereby for the stability and/or performance thereof. The novel variants have improved stability compared to the parental cellulase. In particular, the novel variants have good performance in an antigreying application and excellent stability in the presence of a protease in several detergent compositions even in long-term experiments.
