Tujuan penelitian ini adalah untuk menyeleksi isolat bakteri asam laktat (BAL) yang telah diisolasi dari ikan Kerapu Macan (Epinephelus fuscoguttatus) berdasarkan toleransi terhadap pH dan bile salts, patogenisitas dan kemampuannya menekan pertumbuhan Vibrio alginolyticus pada uji ko-kultur. Hasil penelitian menunjukkan bahwa dua puluh isolat BAL yang telah diuji antagonismenya terhadap V. alginolyticus pada penelitian terdahulu, dapat hidup pada pH rendah 3 dan tumbuh pada konsentrasi bile salts 0,5% kecuali isolat KSBU 13D. Semua isolat tidak patogen terhadap ikan Kerapu Macan setelah diinfeksi BAL pada konsentrasi 107 cfu/ml secara intraperitoneal (IP). Pada uji ko-kultur, dari 6 isolat BAL yang dipilih, tiga isolat (KSBU 12C, KSBU 5Da, KSBU 9) berturut-turut mampu menekan pertumbuhan V. alginolyticus, dan penambahan konsentrasi BAL terbaik adalah 107 cfu/ml.
