title: Microbial fixation of nitrogen in presence of sodium tungstate.
abstract: The effect of sodium tungstate in the culture media of three different species of Azotobacter, isolated from Allahabad soil, was studied. It was observed that the presence of tungstate in the culture media of bacterial sample A2 and A3 decreased the fixation of nitrogen, except in the bacterial sample A1.
