Streamlined copper defenses make

摘要

Growth curves of B. pertussis BPSM and B. bronchiseptica RB50 in SS medium supplemented (blue curves) or not (orange curves) with 5 mM CuSO4 are shown. The turbidity of the cultures was measured using an Elocheck device. The values shown in ordinate (absorbency units) do not correspond to optical density measurements classically obtained with a spectrometer, since the Elocheck instrument uses distinct pathlength and wavelength.
