Abstract

Liquefying alkaline amylases, each having residual activity not less than 70% when treated at pH 10 and 45° C. for 30 minutes in the presence of 1 to 100 mM of EDTA or EGTA, are described. Also described are detergents comprising these amylases. In comparison with conventional amylases for detergents, the liquefying alkaline amylases of this invention have a high chelating-agent resisting performance.
