We have conducted this study to examine effect of kimchi intake on the composition of human large intestinal bacteria. Two hundred grams of kimchi were administered to 10 healthy young volunteers (20-30 years old) every day for 2 weeks, followed by 2 weeks of non-intake period. The non-intake-intake cycle was repeated for 10 weeks. Except antibiotics and materials which contain live bacteria, subjects were allowed to eat ad libitum. The composition of intestinal microflora (Bacteroides, Bifidobacterium, Escherichia coli, Streptococcus, Lactobacillus, Leuconostoc, Staphylococcus, Clostridium perfringens) was examined a1 the last day of each period. $\beta-Glucosidase$ and $\beta-glucuronidase$ activities, pH and moisture content of the fecal samples were also measured. During the administration of kimchi, the cell counts of Lactobacillus and Leuconostoc increased significantly (p<0.05), whereas those of other bacteria did not change significantly. The enzyme level of $\beta-glucosidase$ and $\beta-glucuronidase$ decreased during kimchi intake (p<0.05). Results indicate that a portion of lactic acid bacteria present in kimchi can pass human stomach and reside in the large intestinal tract.
