Susceptibility to nisin.
The sensitivity to nisin of E. faecalis JH2-2 (•) and its derivative mutants Δ_sigV_ (▪) and Δ_dltA_ (▴) was tested on GM17 medium (open symbols) or on GM17 supplemented with 2 µg/ml of nisin (solid symbols). The kinetic growth was monitored at OD600 nm. Mean values of three independent experiments are shown and standard deviations are indicated.
