摘要：

The present study examines antagonistic relationships between different microorganisms inhabiting brackish water and includes a systematic screening for bacteriolytic prokaryotes in the brackish waters of the Southern Baltic Sea (Nordruegenscher Bodden) sampled in July/August 2009. Ten of the 35 marine bacteriolytic isolates belong to the genus Bacillus. Five isolates (B. pumilus, B. subtilis, B. megaterium, B. licheniformis) lysed living microbial cells such as the bacteria Arthrobacter citreus, Arthrobacter protophormiae, Micrococcus luteus, Pseudomonas putida and the yeast Trichosporon mucoides. These and other bacteria (Aeromonas sp., Bacillus subtilis, Chromobacterium violaceum, Citrobacter freundii, Enterobacter aerogenes, Proteus mirabilis, Pseudomonas aeruginosa and Serratia marcescens) were also lysed as autoclaved and pasteurized cells on agar plates. One isolate of Bacillus pumilus showed a distinct bacteriolysis activity against pasteurized cells of A. citreus in liquid culture. Our results suggest that Bacillus species may play a role as opportunistic predators in the marine microbial food web.
