Bacterial strains showing the fibrinolytic activity were screened from Chungkook-jang and Natto (Japanese traditional soy food). The strains isolated from Natto revealed a high level of fibrinolytic activity, wherease nearly half of the isolates from Chungkook-jang did not show the relevant activity. However, one strain isolated from Chungkook-jang showed the highest fibrinolytic activity (1.84 plasmin unit), and subsequently identified as Bacillus species. The fibrinolytic strain was designated as Bacillus sp. CK 11-4.
