Abstract

A screening of antibacterial activity from bacteria associating with soft coral Sarcophyton sp from Tegal island, Lampung, was conducted. The purpose of this screening was to get bacterial isolates that have antibacterial activity with Escherichia coli and Stapiloccocus aureus and also to determine the biochemical characters from the bacteria that have the antibacterial activity. The sample of soft coral was taken by snorkeling at 1,5 meters depth. The bacteria that associated with soft coral were isolated by dilution and pour plate method on NA media. The test of antibacterial activity was done by using agar diffusion method with paper discs. Isolates that have antibacterial activity were tested to check their biochemical characters. From 10 bacteria isolates that have associated with soft coral Sarcophyton sp were obtained, there were two isolates had antibacterial activity (D1.1 to E. coli and D2.2 to S. Aureus). Both bacteria isolates were gram negative and motil. In catalyst test, oxidation, urea, citrate, and carbohydrate fermentation both bacteria isolates showed positive reaction. With VP test, D1.1 isolate showed positive reaction but D2.2 showed negative reaction. In contarary, with gelatin isolate test, isolate D1.1 showed negative reaction but D2.2 positive. Keywords: Bacteria associations, soft corals, Sarcophyton sp, antibacterial, biochemical tests
