Spontaneous mutant of Rhizobium japonicum 3Ilb-138, which was resistant to both 100 μg rifampicin and 100 μg nalidixic acid per ml, was introduced into air-dried soil at the density of 10^8 cells per g of dry soil. The ability of the soil to induce nodulation in soybean declined during the incubation. The soil lost its nodulation ability after 2 weeks of incubation at 40℃. Viable count of the rhizobia decreased to 1×10^6 or 2×10^5 cells per g of dry soil after 4 weeks of incubation of the soil at 30℃ or 40℃, respectively. About 50 colonies were randomly picked up from the nutrient agar plates, and were examined for their nodulation ability. The proportion of cells capable of inducing nodules (Nod^+) to the population of Rhizobium decreased with the incubation of the soil. There were no Nod^+ after 20 days of incubation at 40℃. These results suggest that the proportion of Nod^+ to the population of Rhizobium plays a more important role in the development of nodules than the population size.
