Abstract

Marine microbes serve as an important source for commercial bioactive compounds. The present research is focussed on the Actinobacterial diversity of Machilipatnam coast. Actinobacteria are Gram positive bacteria that resemble Fungi in having filaments forming mycelia colonies. Owing to their morphological and cultural characteristics Actinobacteria are considered a group other than Bacteria. The different Actinobacterial Strains were studied having an ability to utilize the various carbon compounds as source of energy. 27 isolates of Actinobacteria including white, green, grey, orange and pink with different morphological types were isolated from Station I and II. Among them 19 isolates were from Pedapatnam and 27 from Polatitippa. The 27 identified species were falling under 10 genera including Actinobispora, Actinomadura, Actinomyces, Microbispora, Nocardis, Nocardiopsis, Saccharomonospora, Streptomyces, Streptosporangium and Thermomonospora. Streptomyces was the most dominant genus. For the evaluation of antibacterial activity, clinical strains of bacteria such as Gram positive Staphylococcus aureus, and Streptococcus faecalis and Gram - negative Proteus vulgaris and Salmonella typhi were used. Streptomyces alboniger, S.coelicolor and S.griseus were selected to study their antagonistic activity against the above mentioned clinical bacteria. D.
