Deferred antagonism assay and mass spectrometry analysis of nisin A and nisin V. (a) Inhibition of growth of L. monocytogenes EGDe::pPL2luxpHELP by the nisin A producing strain L. lactis NZ9700 and the nisin V producing strain L. lactis NZ9800nisA::M21V. (b) Mass spectrometry analysis of the nisin A (3353 amu) and nisin V (3321 amu) peptides produced by the bacterial strains L. lactis NZ9700 and L. lactis NZ9800nisA::M21V, respectively.
