The aim of the work was to screen among strains of Bacillus isolated from the deepsea ground of the Black Sea, producers with fibrinolytic, elastase and collagenase activities. Methods. To study proteolytic activity casein, fibrin, collagen and congo rot elastin were used as substrates. The protein content was determined by the method of Lowry. Results. As a result of screening among 10 strains of Bacillus isolated from the deep-sea ground of the Black Sea, it was found that the supernatant of the culture liquid of the Bacillus sp. O8 revealed high fibrinolytic activity, while strains 98, 1, and 249 synthesized peptidases with elastase and caseinolytic activities. Collagenase activity was not detected in any of the studied strains. Conclusion. The results of the research allowed to select among the representatives of Bacillus isolated from the deep-sea ground of the Black Sea 4 strains that are promising for further research on the isolation of peptidases with caseinolytic, elastase and fibrinolytic activities from them.

Keywords: strains of Bacillus from the deep-sea ground of Black Sea, elastase, collagenase and fibrinolytic activities.
