Abstract: Most of probiotic isolate is from overseas therefore it needs effort to obtain probiote acid lactid bacteria indigenus.Thepurposeof the research was to obtain viability of Lactobacillus plantarum 1 that isolated from spontaneous fermented soymilk on acid chloride and oxgall. This research used isolate of Lactobacillus plantarum 1 R.11.1.2, Lactobacillus plantarum 1 R.1.3.2,Lactobacillus acidophilus FNCC 0051 and Streptococcus thermophilus FNCC 0040 on medium addition with chloride acid at pH 4, 3, and 2 and addition with oxgall 0.5%.The result showed thatL. plantarum1 R.11.1.2and L.plantarum 1 R.1.3.2 was survive and able to grow on pH 4 during 5 hours incubation.Lactobacillus plantarum1 R.11.1.2andL. plantarum 1 R.1.3.2was survive at pH 3 during 5 hours incubation. Lactobacillus plantarum1 R.11.1.2andL. plantarum 1 R.1.3.2 was unable to survive on pH 2 during neither 2.5 hours nor 5 hours incubation. Lactobacillusplantarum1 R.11.1.2and L.plantarum 1 R.1.3.2 was able to survive on medium with oxgall 0.5%.
