10.22376/ijpbs.2019.10.1.p1-12 Volume 6 Issue 3 2015 (July - September) A total of 28 samples were processed, of which 20 isolates were identified as phosphate solubilizing bacteria. Among 20 isolates, 12 (60 %) belonged to lessThan i greaterThan B. subtilis lessThan /i greaterThan , 3 (15%) were lessThan i greaterThan B. brevis lessThan /i greaterThan , 3 (15%) belonged to lessThan i greaterThan Pseudomonas aeruginosa lessThan /i greaterThan and 2 (10 %) were identified as lessThan i greaterThan Enterobacter aerogenes lessThan /i greaterThan . All the isolates exhibited phosphate solubilization (1.009 µg/ml to 1.609 µg/ml), produced Indole acetic acid (5.46 mg/ml 14.89 mg/ml), protease activity and ammonia production. The isolates produced hydrogen cyanide in the range of 1-5 and were able to tolerate high concentration of insecticide chemorise i.e. upto 5% (v/v). lessThan i greaterThan B. subtilis lessThan /i greaterThan PSB 16 isolates gave the highest values for all plant growth promoting attributes and exhibited growth promotion in lessThan i greaterThan Hordeum vulgare by lessThan /i greaterThan showing enhancement in mean root and shoot length of the plant. PSB isolates showing plant growth promoting attributes has potential to be used as biofertilizer agent.
