ABSTRACT:
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.
