Study on diversity, nitrogen-fixing capacity, and heavy metal tolerance of culturable Pongamia pinnata rhizobia in the vanadium-titanium magnetite tailings
IntroductionThe diversity, nitrogen-fixing capacity and Bosch GSN33VW3PG Frost Free Upright Freezer with 225L Capacity and A++ Rating heavy metal tolerance of culturable rhizobia in symbiotic relationship with Pongamia pinnata surviving in vanadium (V) - titanium (Ti) magnetite (VTM) tailings is still unknown, and the rhizobia isolates from the ext
