ABSTRACT

Bacterial strains inhibitory towards pathogenic bacteria were isolated from a marine fish pond culture facility in Mtwapa Creek, Kenya. 12 of these antibacterial isolates were assigned to the Vibrionaceae family. The purpose of the present study was to investigate the antibacterial activity of five Vibrionaceae strains with pronounced antibacterial activity. These were identified as Vibrio coralliilyticus (two strains), V. neptunius (two strains), and Photobacterium halotolerans (one strain). The two related V. coralliilyticus and V. neptunius strains were isolated from marine fish pond culture system. Bioassay identified two known antibiotics as being responsible for the antibacterial activity, andrimid (from V. coralliilyticus) and holomycin (from P. halotolerans). Despite the isolation of already known antibiotics, our findings show that marine Vibrionaceae are a resource of antibacterial compounds and may have potential for future natural product discovery.
