Effect of different copper concentrations on the growth of L. monocytogenes strain List2-2 and List2-2ΔcbiP cultured in TSBYe agar at 8 °C without (A) or with (B) cyanocobalamin 5 nM cyanocobalamin. The blue rectangle shows the differences in bacterial growth between List2-2 wild-type and List2-2ΔcbiP in agar media without cobalamin. The red rectangle shows the bacterial growth between List2-2 wild-type and List2-2ΔcbiP in agar media with cobalamin
