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

The invention relates primarily to a number of lantibiotics similar to nisin A, which differ from nisin A by substitution, deletion or insertion of one or more amino acids, such as, in particular, the naturally occuring analogue of nisin A, termed nisin Z, which has the structure given above. Lantibiotics of this type are particularly suitable for preserving foodstuffs for humans and animals. This preservation takes place by the use of these lantibiotics themselves or of microorganisms producing these lantibiotics, in particular lactic acid bacteria, in the preparation or storage of foodstuffs.
