In this study, (isolate 29) was isolated traditional yoghurt sample obtained town Hatipli/ Tokat/ Türkiye. And it’s genotypic and characterizations were performed. Our results showed that grew better at pH 5. survival rate in artificial gastric intestinal fluid determined as 47.51% 65.29%, respectively. isolate degraded all tested sodium salts, including Sodium glycocholate hydrate, taurodeoxy Cholate, taurocholic acid, tauroglyco thioglycolate. Its surface hydrophobicity found be moderately 30.31 ± 0.009% n-Hexadecane. Although RA5 antibiotic had largest zone diameter (10 mm), susceptibility not among discs tested. These findings indicated can good probiotics candidate lower cholesterol levels.
