  "abstract": "<p>Hexavalent chromium (Cr) is carcinogenic, mutagenic and causes many health hazards. Some bacteria are capable of resisting high concentrations of hexavalent Cr by converting it into trivalent form, which is non-toxic. The purpose of this study was to isolate&nbsp;<em>Bacillus</em>&nbsp;strains resistant to Cr (VI) and also proficient to promote plant growth. The strains&nbsp;<em>B. rhizosphaerae</em>&nbsp;KAC5,&nbsp;<em>B. clausii</em>&nbsp;KSC6 and&nbsp;<em>B. cereus</em>&nbsp;SLC9 were capable to grow at 500 to 4000 &micro;g/ml Cr (VI). The strains showed growth over wide range of pH (pH 5-11), temperature (32-55&ordm;C) and sodium chloride concentration (up to 5% (w/v). The&nbsp;<em>Bacillus</em>&nbsp;strains showed 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity and produced indole-3-acetic acid (IAA) up to 152 &micro;g/ml. The strains were also positive for phosphate solubilization and siderophore synthesis. Seeds of&nbsp;<em>Triticum aestivum&nbsp;</em>L. treated with&nbsp;<em>Bacillus</em>&nbsp;strains were grown in pots having Cr (VI) concentrations 0, 200 and 500 mg/kg of soil. The&nbsp;<em>Bacillus</em>&nbsp;strains significantly improved the growth of&nbsp;<em>T. aestivum</em>&nbsp;by increasing its shoot length, number of tillers, spike length, number of spikelets, number of grains and seed weight. Hence, the Cr (VI) resistant&nbsp;<em>Bacillus</em>&nbsp;strains showed potential to be used for the growth promotion of plants under chromium stress.</p>",
