Marine microorganisms have unique properties since they had adapted to extreme marine environmental conditions. In this study the in-vitro analysis of novel marine bacterial strains for plant growth promoting potentials like solubilisation of nutrient sources such as phosphate, potassium, zinc, production of phytohormones, organic acid and extracellular enzymes, nitrogen fixation ability, biocontrol activities like production of siderophore, 1-aminocyclopropane-1-carboxylate deaminase and hydrogen cyanide were carried out. Out of 19 morphologically distinct bacterial strains isolated, one predominant and most potent strain designated as MB9 was chosen for antifungal activity against phytopathogens and bioactive metabolite production. The bioactive secondary metabolites from the strain were extracted and identified using Gas Chromatography Mass Spectrometric method.
