Effect of Pseudomonas aeruginosa ZGKD2 on the Growth of Amorpha fruticosa L in Coal Gangue

Article Preview

Abstract:

The cadmium-resistant Pseudomonas aeruginosa strain ZGKD2 was isolated from gangue pile of coal area. Production of siderophores, indole-3-acetic acid (IAA) and the solubilization of phosphate were observed in the strain. Two types of siderophores were identified by UV spectrophotometer. The highest production of IAA and phosphate solubilization were 2.0 ug/mL and 7.2 ug/mL. The root length, plant height and fresh weight of Amorpha fruticosa L in the substrates of Coal gannue and losses were promoted after inoculation with ZGKD2. These data indicated that Pseudomonas aeruginosa strain ZGKD2 was a plant growth-promoting bacterial (PGPB).
