The growth of cells of Escherichia coli has been studied in media with varying amounts of magnesium. Experiments in which the content of magnesium in the medium and in the cell have been directly measured reveal that the growth rate of magnesium-limited wild type cells is half-maximal at extracelhrlar concentrations of 1 to 3 X low6 M. Mutants have been isolated which require 100 times this concentration for half-maximal rate of growth. Supplementation of the medium with calcium or strontium… CONTINUE READING
