Till now many antibiotics are available, but some pathogenic organisms are showing resistance to existing antibiotics. So it is mandatory to search new antibiotics for resisting pathogenic organisms. Actinomycetes are very good resource for producing secondary metabolites that is antibiotics; they are Streptomycin, Erythromycin, and Tetracycline. Actinomycetes are available in both marine and terrestrial ecosystem. From terrestrial ecosystem isolation of new strain actinomycetes is very difficult compared with marine ecosystem. Marine ecosystem is a best resource for many strains of actinomycetes, because it is unexplored ecosystem having millions of different types of microbes. Up to 1% of marine actinomycetes were isolated, but still we have to explore more for discovering new microbes. Most of the isolated marine microbes are from Streptomyces genus (70%), marine fungi (20%), Bacillus spp. (7%) and other bacteria (1%-2%). Present study deals with the collection of soil sample from the coast of Bay of Bengal near Sagar Nagar, Visakhapatnam. This article provides you the future scope.
