Abstract: Symbiotic microorganisms usually have the same secondary metabolite activity as their host. The aims of this study were determine the biodiversity of symbiotic microorganisms from Caulerpa racemosa grown in Lemukutan Island, Indonesia and evaluate their antibacterial activity. Thirty eight bacterial and eighteen fungal were isolated. All isolates showed antibacterial activity against Escherichia coli and Staphylococcus aureus. All fungal isolates were identified from spore morphology using a microscope and, the best bacterial isolates with highest antibacterial activity (IB21 and IB47) were identified using biochemical tests, such as gram staining, citrate test, MR-VP test, carbohydrate fermentation test, fermentative oxidation test, oxidation test, catalase test, indole test, motility test, urease test and hydrogen production test (H2S). The genera of isolated fungi were identified as genus Trichocladium, Aspergillus, Chaetomium, Coprinus, Cladorrhinum, Hymeochaete, Rhizopus, Tremella, Zygorhynchus, Mucor, and Bjerkandera. Meanwhile the best bacteria IB21 and IB47 were putatively identified as member of genus Corynebacterium and Neissiria, respectively.
