Abstract :

Ocean has been considered as a rich source of bioactive compounds having novel structures and biological activities. Actinomycetes are well known for its ability to produce antibiotics. They are gram positive bacteria that consist of a group of anching unicellular microorganisms with high GC content. A study on antibacterial effect of marine actinomycetes against bacterial pathogens was carried out during June 2012 to December 2012. Fourteen different locations of coastal area were selected for sampling. Totally 391 actinomycetes were isolated from the marine soil samples of Tamil Nadu. The antibacterial screening of actinomycetes was checked in modified nutrient agar medium against Bacillus subtilis, Enterobacter sp., Escherichia coli, Proteus sp., Pseudomonas syringae and Pseudomonas aeruginosa. The antibacterial screening showed that, 245 actinomycetes exhibited antibacterial activity against the bacterial pathogens. Thus the result of antibacterial screening represents that the coastal areas of Tamil Nadu are rich in antibacterial antibiotics produced by actinomycetes.
