【 摘 要 】

The ability of 134 bacterial strains isolated from the digestive system of the Japanese sea cucumber Apostichopus japonicus to inhibit the growth of Vibrio alginolyticus, V. parahaemolyticus, V. splendidus, Staphylococcus aureus, Yersinia pseudotuberculosis, Pseudomonas aeruginosa and Escherichia coli was studied. 17 strains (13%) had different level of antimicrobial activity against investigated test -cultures, 8 (6%) of them were bacteria of the genus Bacillus. The highest antimicrobial activity was demonstrated by the strains Bacillus sp. K32, Arthrobacter sp. A16, Kocuria sp. A34, Bacillus megaterium K13 and Pseudoalteromonas sp. K59. The results indicate a high potential of symbiotic microflora of Apostichopus japonicus to confront pathogenic microorganisms.
