Marine microorganisms produce a diverse array of metabolites with novel chemical structures and potent antibacterial activities. Now-a-days, microbial pathogens show antibiotic resistance. Marine bacteria have been shown to produce antibacterial compounds as extensively as terrestrial bacteria. It was reviewed that the bioactive metabolites extracted from bacteria had broad range of antibacterial activity against various antibiotic resistance bacteria which requires more attention in terms of discovery of drugs.
