An extracellular fibrinolytic-enzyme-producing bacterium was isolated from Doen-Jang, a Korean traditional fermented flood, and identified as Bacillus sp. DJ based on its morphology and cellular fatty acid composition. The total extracellular fibrinase (EF) from Bacillus sp. DJ was analyzed using three fibrin zymographic techniques, SDS-fibrin zymography (SDS-FZ), isoelectrofocucing-fibrin zymographs(IEF-FZ), and a two-dimensional SDS-fibrin zymographic analysis (2D SDS-FZ). As a result, the EP map of Bacillus sp. DJ was established. The results suggest that the 2D SDS-FZ method will be a useful tool for the proteomic approach for many other bacterial pretenses.
