The content of trace elements necessary for the normal growth of bacteria was found to have no effect on the intracellular concentration of Ca2+ and Al3+. The content of Cu2+, Fe3+, Mn2+, Mg2+ was considerably reduced. The addition of Mg2+ at different concentrations to this culture medium stimulated the capacity of cells for accumulating not only Mg2+, but also some other ions. Their maximum intracellular concentration was observed when the concentration of Mg2+ in the culture medium was 41 mM. The growth of microbial cells in the standard culture medium containing Mg2+ at a concentration of 4 mM was accompanied by the increased consumption of elements actively participating in redox reactions (Cu2+, Fe3+, Mn2+). Shifts in the ionic composition of microbial cells were manifested by the morphological features of B. pertussis, linked with the increased synthesis of crystalloid structures. The influence of Mn2+, Al3+, Zn2+ at different concentrations on the ionic composition and morphology of B. pertussis was studied.
