  • Publication number: 20170037387
    Abstract: Disclosed are compositions and methods relating to variant alpha-amylases. The variant alpha-amylases are useful, for example, for starch liquefaction and saccharification, for cleaning starchy stains in laundry, dishwashing, and other applications, for textile processing (e.g., desizing), in animal feed for improving digestibility, and for baking and brewing.

  • Publication number: 20170029797
    Abstract: The present invention is in the field of automatic dishwashing detergent compositions, as well as methods of making and using same. In particular, it relates to an automatic dishwashing detergent composition comprising a new protease. The automatic dishwashing detergent composition provides improved cleaning and finishing. In particular the composition of the invention provides better proteinaceous removal at the same level of other proteases available in the market. This also alternatively allows for the use of a lower level of the protease of the invention and therefore a more cost effective composition.
