Lactobacillus pentosus A67 and L. planarum subsp. plantarum C2 was tested the probiotics characterization such as acid, bile acid and antibiotics resistance. Isolates were isolated from the traditional Korean food, collected from traditional markets and homes in Seoul and Gyeonggi Province, and were selected the isolates A67 and C2, which were the most antibacterial to E. coli. According to the analysis of 16S rRNA base sequences, the results showed that L. pentosus ATCC 8041 (similarity 100%), and L. plantarum subsp. plantarum ATCC 14917 (similarity 100%). L. pentosus A67 showed a survival rate of about 98.35% and the L. plantarum C2 showed a survival rate of about 95.62% at pH 2.5, respectively. L. pentosus A67 showed a survival rate of about 94.56% and the L. plantarum C2 showed a survival rate of about 88.81% on the 0.3% bile salt, respectively. L. pentosus A67 and L. plantarum C2 were survived by antibiotics such as the quinolone, aminoglycoside, macrolide, glycopeptide, tetracycline, cephalosporin and phenicillin families. On basis of these results, L. pentosus A67 and L. plantarum C2 are the candidates for useful probiotics.
