The studThe Tolerance of Lactobacillusy conducted to obtain Lactobacillus species from bovine colostrum as probiotic candidate that have resistant character towards acidity and bile salt condition. Research done experimentally with Factorial Completely Randomized Design Pattern. The results were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT). Results showed that L. paracasei and L. curvatus have tolerance of pH 2 with colony population by 0.07×102 CFU/mL. L. paracasei and L. curvatus also have tolerance as well towards 0.3% of bile salt concentration with colony population by 4.05×1010 CFU/mL and 0.5% of bile salt concentration with colony population by 4.02×1010 CFU/ml. L. paracasei and L. curvatus have character as probiotic because grew well at high acidity and bile salts condition.
