Abstract
Terasi is one of the fermented product of shrimp or fish which is often used as food seasoning by the people. Terasi is also a source of Lactic Acid Bacteria (LAB) which has the potential as a culture for probiotic starters. Probiotics are dietary supplements containing live microbes that profitable to their hosts. This study aimed to identify probiotic lactic acid bacteria isolated from terasi of shrimp based on the 16S ribosomal ribonucleic acid (rRNA) gene sequence. LAB isolation from terasi was done by pour plate method using selective medium, MRSA (Man Rogosa Sharpe Agar). The identification of LAB in this study used a method of molecular with a marker gene of 16S rRNA . A total of 3 isolates were obtained from the isolation process. All LAB isolates are rod (Basil) positive Gram bacteria, negative catalase. Two isolates (TR 1 and TR 2) were identified as Enterococcus faecalis . While one more isolate (TR 3) were identified as Weissella cibaria .

Summary
Indonesia kaya akan makananan fermentasi tradisional yang dibuat dari bahan berupa produk pertanian dan dari hasil laut. Menurut Afrianto dan Liviawaty (2005), terasi merupakan suatu produk hasil fermentasi ikan atau udang yang mengalami perlakuan penggaraman. Bakteri asam laktat (BAL) banyak ditemukan pada produk fermentasi dan telah dilaporkan banyak berfungsi sebagai probiotik. Beberapa penelitian mengenai isolasi dan identifikasi bakteri dalam produk terasi sudah pernah dilakukan oleh Munaroh (2013) yang memperoleh enam isolat berupa gram positif, katalase negatif, non-motil dan bersifat homofermentatif serta heterofermentatif.
