Many of the ecological factors of the marine environment were helpful in developing a strategy for discovering useful bioactive agents from marine microorganisms. Among them actinobacteria have gained special importance as they play a major role in recycling of organic matter, production of novel pharmaceuticals, cosmetics, enzymes, antitumor agents, enzyme inhibitors, immune-modifiers and vitamins. The present study was carried out to isolate actinobacteria, which have potential to produce enzymes from selected marine samples. A total of eleven isolates of actinobacteria were isolated and were characterized morphologically. Screening test was performed to determine analyse, protease and lipase activity. Almost all the isolates showed enzyme production from the potential actinobacteria. Then active isolates were selected for secondary screening by agar well diffusion method. The efficacy of potential antibacterial properties of all the strains of actinobacteria were tested against E.coli, P.aeroginosa, K.pneumoniae and S.aureus performed respectively. The maximum antibacterial activity of SVA3, SVA10 and SVA11 strain has been responsible against P.aeroginosa and K.pneumoniae bacteria.
