NOVEL MANNANASE VARIANTS

The present disclosure provides novel mannanase variants which have an amino acid sequence that varies from that of the parent/wild type Trichoderma reesei mannanase， and which have one or more advantageous properties like improved thermo stability; temperature/activity profile; pH/activity profile; specific activity; and pH/protease-sensitivity. The novel mannanase variants are useful and used in alcohol fermentations processes and/or productions， for coffee extraction and the processing of coffee waste， as a supplement to food and feed， for enzyme aided bleaching of paper pulps， as bleaching and/or desizing agent in textile industry， for oil and gas well stimulation by hydraulic fracturing， as detergent， as baking ingredients， for removal of biofilms and in delivery systems， for grain processing or for the processing of renewable resources intended for the production of biological fuels， and in the textile， oil drilling， cleaning， laundering， detergent， and cellulose fiber processing industries The present disclosure provides novel mannanase variants which have an amino acid sequence that varies from that of the parent/wild type Trichoderma reesei mannanase， and which have one or more advantageous properties like improved thermo stability; temperature/activity profile; pH/activity profile; specific activity; and pH/protease-sensitivity.
