title: Study of the inducer effect of molasses and soybean cake on synthesis and excretion of nodulation factors in different strains of Bradyrhizobium japonicum.
abstract: It is known that the synthesis of nodulation factors by the bacteria within the genera Rhizobium is induced by different compounds, mainly of flavonoid nature exudated by the legume plants. The capacity of different compounds to act as inducers of nod genes on three Bradyrhizobium japonicum strains was studied in this paper and this effect was compared using two concentrations of the inducer. Induced Nod factors were observed among the strains exposed to the inducers. The profiles and amount of induced Nod factors depend on the type and concentration of the inducer, and the strains.
