Abstract
Soybean nodule extract was prepared and tested for the effectiveness in the induction of asymbiotic nitrogen fixation of R. japonicum P-168. Asymbiotic nitrogenase activity was increased over twice when glutamate was replaced by nodule extract in the induction media. Independently of the induction media, the nitrogenase activity in the assay media was also enhanced by the addition of nodule extract (100-400 micro g protein/ml). The amount of ethylene in the assay media reached the highest point after 8 days incubation of R-168 and was decreased thereafter. The growth of R. japonicum R-168 was sensitive to the concentration of nodule extract
