Soft corals are leathery colonial invertebrates that are classified under the phylum Coelenterata, of class Anthozoa and subclass Octocorillia. They are said to form an extensive portion of the cover and biomass of most reefs in the Indo-Pacific (Dinesan,1983) and even in the Red Sea (Benahayu & Loya, 1981). Their ability of soft corals to dominate the benthic community had been attributed to their ability to overgrow other organisms, manner of reproduction and recruitment, seemingly negligible specific predators, and/or production of toxic secondary metabolites that effect tissue necrosis or stunted growth on their neighbor.
This study explores the antibacterial activity of soft corals found in Tando, Nueva Valencia, Guimaras against the plant pathogen Xanthomonas oryzae pv. oryzicola.
Methanolic extracts of the soft corals were used to treat the bacteria Xanthomonas oryzae pv. oryzicola.
Results showed that there was no antibacterial activity found in the soft coral extracts tested against the plant pathogen Xanthomonas oryzae pv oryzicola.
