ANTAGONISTIC ACTIVITY OF ENDOSPOREFORMING BACTERIA OF DEEP WATER THE BLACK SEA SEDIMENTS
Journal Title: Мікробіологія і біотехнологія - Year 2018, Vol 0, Issue 3
Abstract
Aim. The purpose of the work was to study the antagonistic activity of strains of the facultatively anaerobic endosporeforming bacteria, isolated from deep-sea sediments of the Black Sea. Materials and methods. In this work, 250 strains of facultative anaerobic endosporeforming bacteria, isolated from the samples of deep-sea sediments of the Black Sea, were used. Antagonistic activity was determined by the method of radial streaks. As indicators for screening there were used next strains of opportunistic human pathogens – Proteus vulgaris ATCC 6896, Pseudomonas aeruginosa B-329, Staphylococcus aureus ATCC 6538P, Bacillus cereus ATCC 14579, Candida albicans ATCC 10231, Escherichia coli ATCC 25922, Salmonella enterica NCTC 6017, Klebsiella pneumoniae ATCC 10031, Bacillus subtilis ATCC 10774. Results. It is revealed that 32% of all isolated Black Sea strains of facultative anaerobic spore-forming bacteria have been shown to exhibit antagonistic activity of varying degrees of severity in relation to opportunistic microorganisms. There is a certain relationship between species strain, horizon of its origin and its antagonistic activity. Conclusions. The obtained results testify to the promising nature of the strains of endosporeforming bacteria in the Black Sea sediments for the screening of the producers of antimicrobial compounds with activity directed against opportunistic human pathogens
