LANTIBIOTICS SIMILAR TO NISIN A, LACTIC ACID BACTERIA WHICH PRODUCE SUCH LANTIBIOTICS, METHOD FOR CONSTRUCTING SUCH LACTIC ACID BACTERIA AND METHOD FOR PRESERVING FOODSTUFFS WITH THE AID OF THESE LANTIBIOTICS AND THESE LACTIC ACID BACTERIA PRODUCING LANTIBIOTICS

摘要

It primarily describes a number of lantibiotics similar to nisin A but different therefrom by substitution, deletion or insertion of one or more amino acids, including natural analogue of nisin A called nisin Z, which structure is shown above. This type of lantibiotics is adapted especially to the conservation of foodstuffs for humans and animals. This retention may be performed during the preparation or storage of foodstuffs, using these actual lantibiotics or microorganisms which produce them, including bacteria of lactic acid.
