dc.description.abstractPlant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. In search of efficient PGPR strains with multiple activities, a total of 150 bacterial isolates belonging to <em>Bacillus,</em> <em>Pseudomonas, Azotobacter and Rhizobium </em>were isolated from different rhizospheric soil of chick pea in the vicinity of Allahabad. These test isolates were biochemically characterized and screened <em>in vitro</em> for their plant growth promoting traits like production of indoleacetic acid (IAA), ammonia (NH3), hydrogen cyanide (HCN), siderophore and catalase. All the isolates of <em>Bacillus, Pseudomonas </em>and<em> Azotobacter </em>produced IAA, whereas only 85.7% of <em>Rhizobium</em> was able to produce IAA. Production of ammonia was commonly detected in the isolates of <em>Bacillus</em> (95.0%) followed by <em>Pseudomonas</em> (94.2%), <em>Rhizobium</em> (74.2%) and <em>Azotobacter</em> (45.0%). All test isolates were positive for catalase but none of the isolates produced HCN. On the basis of multiple plant growth promoting activities, 20 bacterial isolates of each genus, in total 80 isolates, were evaluated for their heavy metal tolerance. Among these isolates, <em>Bacillus </em>spp. were tolerant to all the heavy metals (400 µg ml<sup>-1</sup>), whereas <em>Pseudomonas</em> spp. were tolerant to Hg (100 µg ml<sup>-1</sup>), Co (100 µg ml<sup>-1</sup>), Cd (200 µg ml<sup>-1</sup>), Cr (100 µg ml<sup>-1</sup>), Cu (200 µg ml<sup>-1</sup>), Pb (400 µg ml<sup>-1</sup>), Zn (200 µg ml<sup>-1</sup>). Tolerance to heavy metals was observed less frequently in <em>Azotobacter</em> spp. and <em>Rhizobium</em> spp. The isolates could exhibit more than two or three PGP traits, which may promote plant growth directly or indirectly or synergistically. Further, rhizobacteria tolerant to multiple heavy metals exhibited a couple of PGP activities.en_US
