ANTI-PATHOGENIC ACTIVITY OF CORAL BACTERIA AGAINST WHITE PLAQUE DISEASE OF CORAL FAVIA SP. FROM TENGAH ISLAND KARIMUNJAWA INDONESIA
Coral disease is main factor of degrading coral reefs, such as White Plaque (WP) disease that cause loss of epidermal tissue of coral. The purposes of this research were to identify the bacteria associated with White Plaque Disease of coral Favia sp. and to investigate coral bacteria that have antipatogenic potency against White Plaque Disease of Coral Favia sp. Sampling was carried out by purposive method in Tengah Island, Karimunjawa on March 2015. Streak method was used to isolate and purify coral bacteria, while overlay and agar diffusion method were used to test antibacterial activity. Identification of selected bacteria were conducted by biochemical and molecular methods. Polyphasic identification of bacteria associated with diseased coral White Plague of Favia sp. showed that TFWP1, TFWP2, TFWP3 and TFWP4 were closely related to Bacillus antracis, Virgibacillus olivae, Virgibacillus salarius and Bacillus mojavensis, respectively. While antipatogen activity bacterial isolates, NM1.3, NM1.8 and NM2.3 were closely related to Pseudoalteromonas flavipulchra, Pseudoalteromonas piscicida, Vibrio azureus, respectively. Phylogenetic data on microbial community composition in coral will help in the knowledge on the biological control of coral diseases.
