Study on the Useful Marine Bacteria from the Coastal Waters of Iriomote Island, Japan

Rasyid A.


The screening of 86 marine bacterial strains associated with marine invertebrates, algae, sediment, artificial sponges and sea water from the coastal waters of the Iriomote Islands (Japan) has been carried out. The purpose of this study was to get various strains of marine bacteria that are beneficial to the production of bioactive compounds. The screening of antibacterial activity produced by strains of marine bacteria was carried out using the paper disk method. Antibacterial activity test results showed that one strain of bacteria showed some activity against Bacillus subtilis and Cautobacter halobacteroides, two strains of bacteria showed some activity against Staphylococcus aureus, four strains of bacteria showed some activity against Cytophagamarinoflava, 63 strains of bacteria showed some activity against Vibrio harveyi and 14 strains of bacteria showed some activity against Pseudovibrio sp., while Salinivibrio costicola showed no antibacterial activity. This indicates that about 78% of all the bacterial strains isolated have the potential to produce bioactive compounds
