简介
In the present study, the Cicer arietinum (chickpea) rhizosphere bacterial strains Azotobacter chroococcum (AU-1), Bacillus subtilis (AU-2), Pseudomonas aeruginosa (AU-3) and Bacillus pumilis (AU-4) were isolated and characterized for plant growth-promoting traits with an aim of developing bio-fertilizing agent to improve growth and yield of chickpea plants under normal conditions. The ACC degrading potential of strains AU-1, AU-2, AU-3, and AU-4 was in the range of 600–1700 nmol α-ketobutyrate per mg of cellular protein per hour, respectively. These four rhizobacteria exhibited Indole acetic acid production approximately between 20 and 35.34 µg/ml. The phosphate solubilization potential was in the range of 78–87.64 mg Soluble P/L with maximum solubilization displayed by strains P. aeruginosa and B. pumilis. All the growth-promoting isolates displayed Fe-chelating siderophore and ammonia …
