Abstract

Using the Warburg micro-manometric technique, the influence of nitrogenous compounds on the respiratory activities of the legume root-nodule bacteria has been recently studied. It was observed in these studies that the form in which the nitrogen was supplied to the organisms greatly influenced the amount of oxygen which they consumed. The fact was apparent that the effect of the nitrogen source might be due either to a stimulation or depression of the respiration of the organisms or to a marked change in its respiratory quotient; i.e., the ratio of oxygen consumed to carbon dioxide produced, CO₂/O_2. In order to throw light on this problem, a study of the influence of various nitrogenous compounds on the respiratory quotient of Rhizobium was initiated. Strains of Rhizobium trifolii, Rh. meliloti, Rh. lcguminosarum and Rh. japonicum were used.
