Cross-reactivity of bacteriocins from lactic acid bacteria and lantibiotics in a nisin bioassay and ELISA.
A number of bacteriocins from lactic acid bacteria and lantibiotics were tested for cross-reactivity in a nisin ELISA and bioassay. The bacteriocins showed no cross-reactivity, reflecting their structural dissimilarity from nisin. The lantibiotic subtilin which shares many common structural features with nisin, showed a high cross-reactivity in both the ELISA and the bioassay suggesting possible modifications to nisin to enhance its activity. Gallidermin did not cross react in the ELISA but did produce a zone of inhibition in the less specific bioassay. Other lantibiotics tested did not react in either assay.
