dc.description.abstractPenelitian ini bertujuan untuk menapis dan mengkarakterisasi isolat bakteri asam laktat (BAL) yang diperoleh dari saluran pencernaan ayam broiler (Gallus domesticus). Penelitian dilakukan melalui isolasi dan identifikasi BAL menggunakan metode pewarnaan gram dan pengujian biokimia. Hasil isolasi menunjukkan delapan isolat BAL (sp1-sp8), yang secara makroskopis memiliki bentuk koloni bervariasi, sebagian besar bulat dengan warna putih. Pengamatan mikroskopis menunjukkan bahwa seluruh isolat berbentuk batang (basil) dengan sifat gram positif. Uji biokimia memperlihatkan hasil positif untuk fermentasi sitrat, motilitas dan katalase pada semua isolat. Berdasarkan hasil ini, BAL yang diisolasi memiliki potensi untuk dikembangkan sebagai kandidat probiotik. This research aimed to screen and characterize lactic acid bacteria (LAB) isolates obtained from the digestive tract of broiler chickens (Gallus domesticus). The research was conducted through the isolation and identification of LAB using gram staining and biochemical testing methods. The isolation results showed eight LAB isolates (sp1–sp8), which macroscopically had varying colony shapes, mostly round with white color. Microscopic observations showed that all isolates were rod-shaped (bacilli) and gram-positive. Biochemical tests showed positive results for citrate fermentation, motility, and catalase in all isolates. Based on these results, the isolated LAB had the potential to be developed as probiotic candidates.en_US
