Effect of Different Carriers on Shelf Life of Bradyrhizobium japonicum
During present investigations shelf life of Bradyrhizobium was studied by using differentcarriers viz., lignite, glycerol, polyvinylpyrrolidone (PVP), ethylene diamine tetra-acetic acid (EDTA), gum arabica mixed with 10, 15, 20, 25, 30 and 35 ml Bradyrhizobium broth combination. The viability count was taken by serial dilution method at 30, 60 and 90 days after inoculation.
