Abstract

A minimum concentration of 0.01 mM of Mg²⁺ was essential for any growth of S. aureus. Of the trace metals, Mg²⁺ and Ca²⁺ were highly stimulatory for growth. All trace metals except Ni²⁺ in small concentrations were stimulatory for growth and exoprotein production. Amounts of exoprotein and β-lactamase produced relative to the number of viable cells were maximum during the period of suboptimal proliferation of bacteria. Trace metals did not significantly influence the amount of β-lactamase produced relative to exoprotein.
