Penelitian menunjukkan bahwa bakteri simbion karang Porites memiliki potensi antibakteri dalam menanggulangi bakteri patogen. Penelitian ini betujuan untuk mengetahui jenis bakteri simbion karang Porites dari Perairan Gunungkidul Yogyakarta yang memiliki aktivitas antibakteri patogen S. aureus dan E. coli. Bakteri simbion diisolasi dari fragmen jaringan karang dengan pengenceran bertingkat, kemudian uji aktivitas antibakteri dilakukan dengan menggunakan metode overlay dan difusi paperdisk. Delapan dari 64 isolat aktif menghambat kedua bakteri patogen Staphylococcus aureus dan Escherichia coli. Dua diantaranya merupakan isolat unggul yang menunjukkan aktivitas antibakteri paling baik. Kedua isolat selanjutnya diidentifikasi karakteristik molekular DNA dengan sekuen gen 16S rRNA. Hasil identifikasi 16S rRNA menunjukkan isolat GKP1.4.3 memiliki kesamaan 99% dengan Bacillus pumilus strain NBRC 12092, dan isolat GKP3.2.2 memiliki kesamaan 99% dengan Vibrio natriegens strain NBRC 15636.
