A novel detergent composition containing an alkaline pullulanase is disclosed. The alkaline pullulanase has its optimum pH in an alkaline range and not deactivated by surfactants. Further it has strong resistance to almost all detergent components such as chelating agents, protease, etc. The the detergent composition of this invention has excellent detergency especially against starch soils.

Detergent composition containing alkaline pullylanase enzyme

A detergent composition containing an alkaline pullulanase, a surfactant, alkaline agents and/or inorganic electrolytes, divalent metal ion scavengers and bleaching agents is disclosed. The alkaline pullulanase has an optimum pH range of 8.5-10.0 on pullulan, an optimum temperature of about 50.degree. C. and is not deactivated by surfactants. Further, the pullulanase has a strong resistance to almost all detergent components such as chelating agents, proteases, etc. The pullulanase is isolated from Bacillus sp. KSM-AP 1378 deposited as FERM BP-3048. The composition specifically contains 0.1-10 wt. % alkaline pullulanase B, 0.5-60 wt. % surfactant, 0-90 wt. % alkaline agents and/or inorganic electrolytes, 0-50 wt. % divalent metal ion scavengers, and 0-85 wt. % bleaching agents.
