Intestinal lactic acid bacteria (LAB) for humans are closely associated to the host’s health because the presenceof LAB is an important bio-defense factor in preventing colonization and subsequent proliferation of pathogenic bacteria inthe intestine. Some probiotics such as Lactobacillus species can intoxication of carcinogens including chemical mutagens.The purpose of this study was to compare the ability of antimutagenesity among 24 strains of LAB isolated from infantfeces, yogurt and kimchi etc. The antimutagenic effects of protein fractions extracted from the cells of 24 LAB strains wereinvestigated using mutagens as 4-nitroquinoline-N'-oxide in Ames test (Salmonella Typhimurium TA 100). In the Amestest, dose-dependent activity was exhibited significantly against 4NQO. Three strains of Lactobacillus showed the highestanti-4NQO activitiy (62.1%) among the tested strains of LAB.
