Abstract:
:The diversity, distribution, and mechanisms of bacterial speciation of Vibrio species belonging to Harveyi clade are an important global research interests due to their pathogenic activity in coastal environments. Luminous bacteria are also known to act as environmental indicators in coastal waters. This study demonstrates that luminous bacteria belonging to harveyi clade are predominant in seawater, sediment, surfaces of marine animals and plants, and light organs of leiognathid fishes. Molecular phylogenies for eighteen morphologically distinct and potentially luminous strains chosen out of 57 isolated luminous bacteria. Sequence analysis of luxA gene as a molecular marker identified luminous bacteria belonging to Harveyi clade, Photobacterium clade, and Anguillarum clade distinctly. Rich biodiversity and distribution of luminous bacterial species (30% to 40%) was found in association with coral reef samples of south Andaman. This study confirms and reveals the evidence on predominant association of Harveyi clade luminous vibrio's in coastal waters of south Andaman.
