A) Acid and bile salt tolerance of both H. coagulans isolates compared to control L. plantarum B-17 and B. amyloliquefaciens (TBRC-15434). Bar graphs represent survival rates of two H. coagulans isolates and a control (L. plantarum and B. amyloliquefaciens) strain under acidic (pH 3.0) and 1% bile salt conditions over a 3-hours. Each bar denotes the mean ± SD from three independent experiments. B). Screening of acid production in Modified GYE-PBS medium. C). Temperature tolerance of both H. coagulans isolates to six different temperatures (37 °C, 40 °C, 45 °C, 50 °C, 55 °C, and 60 °C)
