Eksplorasi Bakteri Asam Laktat dengan Aktivitas Antibakteri dari Urutan sebagai Kandidat Probiotik

Lactic Acid Bacteria (LAB) species grow naturally during the fermentation process of Urutans. This research aims to isolate LAB from Urutan and study its ability inhibit pathogenic bacteria. According FAO/WHO, antagonistic activity against enteric microbes is one criteria for probiotic products. The was conducted with an exploratory method at Microbiology Laboratory Faculty Medicine, Udayana University, February June 2020. samples were five Urutans traders in Baturiti District, Tabanan-Bali. isolated using MRS agar media supplemented 1% CaCO3. suspects further confirmed by catalase test Gram staining. results showed 326 isolates as colonies characteristics acidifying growth media, catalase-negative, Gram-positive rods cocci. Antibacterial on that 29 inhibited Escherichia coli 46 Staphylococcus aureus. A total 158 other E.coli, S. aureus, 93 no inhibitory both. E.coli S.aureus could be studied developed candidates.
