Antibacterial and pharmaceutical potential of marine isolates are considered as a significant objective in the present
research. Marine actinomycetes were isolated and screened for its antibacterial activity. Five isolates showing chalky white and
whitish grey colour colonies were isolated and designated as ACT1, ACT2, ACT3, ACT4 and ACT5. ACT2 exhibited the inhibitory
zones of 20mm, 19mm, 19mm and 22mm respectively against Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC
25922), Bacillus subtilis (ATCC 6051) and Staphylococcus aureus (ATCC 9144). ACT5 showed maximum inhibitory zones of
22mm, 18mm, 21mm and 24mm against the respective test organisms. Thus, the obtained results in the present research revealed
the pharmaceutical applications of marine metabolites. The types of antibiotics and its structures synthesized by the marine
isolates shall be studied as future study.
