Penelitian ini bertujuan untuk menseleksi bakteri probiotik yang akan dikembangkan sebagai materi dasar untuk mengkonstruksi konsorsium probiotik dengan target fungsional di saluran pencernaan ikan kerapu. Salah satu kriteria seleksi ditetapkan berdasarkan desain konstruksi konsorsium gut probiotik yaitu kemampuan menghasilkan senyawa antibakteri terhadap bakteri pathogen dan kemampuan menghasilkan enzim pencernaan diantaranya adalah enzim proteolitik ekstraseluler.

Hasil seleksi berdasarkan kriteria seleksi yang telah ditetapkan diperoleh 8 isolat bakteri potensial untuk dapat dikembangkan sebagai konsorsium probiotik. Ke 8 isolat ini mempunyai kemampuan untuk menghasilkan senyawa antibakteri yang aktif terhadap 4 jenis vibrio ( V. parahaemolyticus , V. vulnivicus , V. harveyii , dan V.anguilarum ) serta menghasilkan enzim proteolitik ekstraseluler yang diperlukan untuk mencerna senyawa yang bersifat protein yang merupakan komponen utama pakan ikan Kata kunci: Probiotik, pengendalian penyakit, antibakteri, enzim proteolitik, saluran pencernaan, ikan kerapu The strategy to healhty fish in an integrated manner is one of the efforts that is the most effective to environmentally friendly disease control.

Antibacterial activity was detection by agar diffusion method using paper disk, while the detection capability to produce extracellular proteolitic enzymes was carried out by using enrichment media with skim milk.
