Abstract:
PURPOSE: A composition containing bacteriocin cerein 13061 for killing germ is provided to replace antibiotics used in the food industry or livestock industry. CONSTITUTION: A polypeptide with a bacteriocin activity contains an amino acid sequence of sequence number 1 or 2. A polynucleotide encoding the amino acid of sequence number 1 has a nucleic acid sequence of sequence number 3. A polynucleotide encoding the amino acid of sequence number 2 has a nucleic acid sequence of sequence number 5. A composition for killing germ independently contains the polypeptide of sequence number 1 or 2 or a combination of the polypeptides. The composition contains a culture of Bacillus cereus ATCC 13061 as an active ingredient.
