The present invention relates to isolated polypeptides having alpha-
amylase activity, polypeptides comprising an alpha-
amylase catalytic domain and a
carbohydrate binding module, and polynucleotides encoding the polypeptides, compositions comprising said polypeptides, as well as polynucleotides and
nucleic acid constructs or vectors encoding the polypeptides, and host cells comprising the polynucleotides or constructs / vectors, as well as methods of producing and using the polypeptides.
