LEON, Jorge et al. Marine bacteria producing antibacterial compounds Isolated from inter-tidal invertebrates. Rev. perú. med. exp. salud publica [online]. 2010, vol.27, n.2, pp.215-221. ISSN 1726-4634.

Prospective sampling activities of intertidal invertebrates in the Ancon Bay (Lima, Peru) were done in order to select marine bacteria producing antimicrobial substances. The study included the isolation of bacteria in marine agar, in vitro antimicrobial susceptibility testing and electronic microscopic observations. We report the isolation, phenotypical characterization and antimicrobial properties of 10 strains of marine bacteria including the genus Vibrio, Pseudomonas, and Flavobacterium, and the order Actinomycetae that inhibit human pathogens. The results indicate that the marine invertebrates would be sources of bacteria producing antibiotic substances.
