A heavy metal tolerant Azospirillum sp. was isolated from different sources. These isolates were characterized and identified as Azospirillum lipoferum. These isolates tolerate more concentration of heavy metals and studied for production of IAA. These isolates were used to study efficiency in soil with the heavy metal as biofertilizer with plant Triticum aestivum var LOK-1. The impact of these isolates as a biofertilizer, clearly show significant results for growth of plant and shows increase number of Azospirillum lipoferum.

Keywords : Azospirillum lipoferum, IAA, heavy metals tolerance, Triticum aestivum var LOK-1.
