• Oxygen resistant N sub(2)-fixing Escherichia coli), which can grow at a high oxygen concentration in a nitrogen-free medium, were produced by several times of cultivation under a condition of 0.03% oxygen. Six isolated resistant strains could grow at an oxygen concentration ten times that of the parent strain. The nif -genes of these six strains were integrated into a chromosome. At low oxygen, they showed one third the nitrogenase activity to the parent strain, but more so at a high oxygen concentration.
