Abstract

Surmmary

Comparative studies of growth, yield of organism and synthesis of nucleic acids were made on a strain of grown with and without sufficient iron. Although the bacteria grew exponentially at the same rate in the iron-deficient medium as in the iron-replete medium, the content of RNA and DNA was lower in the iron-deficient bacteria. In the iron-deficient cultures, growth ceased abruptly after an exponential phase characterized by an inhibition of DNA synthesis. The pH value of the medium became increasingly acidic as iron-deficient growth proceeded.
