Abstract

Summer Gut Syndrome (SGS) is caused by various Vibrio Bacterial species and can have negative effects on aquaculture farms worldwide. In New Zealand, SGS is caused by Vibrio harveyii infecting King Salmon (Oncorhynchus tshawytscha). To find leads for the prevention of SGS, we screened the inhibitory effects of 16 strains of Shewanella upon V. harveyii growth in competitive solid phase cultures. The detailed investigation of Shewanella halifaxensis IRL548 revealed 2-benzyl-4-chlorophenol (1), a known, commercially available Antibacterial agent, as the major bioactive component. Synthesis of a small library of congeners to confirm the natural product identity and to provide a structure-activity relationship for the observed activity was also completed. Compound 1 exhibits moderate activity against two pathogenic Microorganisms.
