Microorganisms associated with the marine invertebrate contain a higher proportion
of antibacterial activities but only a limited works are available. The rapid evolution of
antimicrobial resistance has been a major problems in the last three decades.
Therefore, the aim of this study was to isolate and characterize bacteria from the
surface and gut of polychaete; to determine the antibacterial activity produced. The
bacteria was isolated from the surface and gut of polychaete using spread plate
method and identified based on morphology and biochemical test. The antibacterial
activity of the crude protein extracts were tested using disc diffusion method. As a
result, both of the sample pointed an inhibitory activity. Based on the result, it can be
concluded that the bacteria from polychaete are beneficial to produce strong
antibacterial activity.
