Diverse nitrogen fixing microorganisms (aerobes, facultative anaerobes, heterotrophs, phototrophs) grow in the rhizosphere of tea and contribute to the soil nitrogen pools. The recent isolation and study of free-living nitrogen fixing bacteria represent an exciting period in the field of biological nitrogen fixation. The present investigation was carried out in tea gardens of south Assam in the month of August to December, 2010. Seventeen strains of nitrogen fixing bacteria of the genus Beijerinckia was isolated and identified based on their morphological and biochemical characteristics.
