Abstract: Disclosed are compositions and methods relating to alpha-amylase from Exiguobacterium. The compositions and methods 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 and for baking and brewing.
