Isolation and identification of bacteria from marine biofilm on the artificial plat forms (iron panels) from Visakhapatnam coast, India

Abstract

Visakhapatnam coast is natural and colossal, the fishing harbor, Iron ore jetty of Visakhapatnam port, and Naval

dockyard canal areas are studied for the locally associated biofilms. In the present study, Culturable bacteria forming marine biofilms were isolated and identified on artificial substrate (iron panels) according to Bergey, from Visakhapatnam coastal area, Northern Andhra Pradesh. Mainly 3 genera of 10 species were identified, they are <i>Bacillus weihenstephanensis, Bacillus flexus, Serratia nematodiphila, Bacillus halotolerans, Bacillus aerius, Vibrio natriegens, Bacillus vallismortis, Bacillus endophyticus, Bacillus thuringiensis, Vibrio hepatarius. </i>Where <i>bacillus sps</i>. are dominant and commonly found in all the three stations, <i>Vibrio </i>and <i>Serratia </i>were found in two stations.
