In order to produce a high quality and functional black bean Chungkugjang, a bacterium which has potent enzyme activities(protease:124.8 U/$mell$, $alpha$-amylase: 78.2U/$mell$, glucoamylase; 13.9U/$mell$, ), was isolated by using the halo zone method and identified by morphological, cultural and biochemical properties, and then finally confirmed by GP-microplate identification system as Bacillus megatrium SMY-212. The isolated SMY-212 system was also high in the formation of mucoid material and fibrinolytic activity.
