    • PURPOSE: A bacteriocin produced by Bacillus polyfermenticus showing direct antibacterial action against Helicobacter Pylori as a causative agent of gastritis is provided. Therefore, it can be used in the treatment of acid peptic disease such as gastritis and duodenal ulcers by oral administration. CONSTITUTION: A bacteriocin as an antimicrobial substance produced by Bacillus polyfermenticus controls or eradicates Helicobacter pylori. For an example, Bacillus polyfermenticus is cultured in a TBS(Difco laboratories) medium, Helicobacter pylori(KCTC 2948) is cultured in a Mueller hinton medium added with 10% bovine calf serum at 37deg.C under anaerobic conditions. Helicobacter pylori in the amount of 10¬6 cfu/ml is smeared to a solid medium and cultured, Bacillus polyfermenticus(10 microliter) remaining in a logarithmic growth phase is spotted and cultured. In the test, the inhibiting effect on the growth of Helicobacter pylori is distinctly observed.
