SUPPRESSION OF HISTERIA MONOSITEGENES USING BACTERIOSINE

摘要

PURPOSE: To prevent contamination of foods by Listeria monocytogenes by using a bacteriocin produced by Pediococcus acidilacteici. CONSTITUTION: Pediococcus acidilacteici NRRL-B-18050 which has a DNA having a genetic code to produce bacteriocin as a plasmid in the Pediococcus acidilacteici is grown, and the growth medium is filtered through a membrane to obtain a soln. containing the bacteriocin. The soln. is dried to obtain a bacteriocin in a powder state. The obtd. powder is added into milk, meat, cheese or other foods in an effective amt. to suppress growth of Listeria monocytogenes, for example, by 1 to 100,000AU per 1g of a food.
