Abstract
Marine bacteria were isolated from seawater was collected from different coastal areas of the
Tamilnadu Sea. The antimicrobial activities of these bacteria were investigated. Ethyl acetate
extracts of marine bacterial fermentation were screened for antimicrobial activities using the
method of agar diffusion. The results showed that 25 strains of the isolates have antimicrobial
activity. The proportion of active bacteria associated with isolated from seawater. The active
marine bacteria were assigned to the genera Alteromonas, Pseudomonas, Bacillus and
Marinobacter. The TLC autobiographic overlay assay implied that the antimicrobial
metabolites produced by four strains with wide antimicrobial spectrum were different. These
marine bacteria were expected to be potential resources of natural antibiotic products. It can
be concluded that isolation of Marine bacterial samples can offer a numbers of microbial
strains for sources of new biomolecules from Marine sources.
