摘要：

With the aim to select rhizobacteria exhibiting several plant growth promoting traits, 5 isolates were evaluated. Phosphate (P) solubilization halos were between 0.4 and 0.9 cm, and P concentrations ranged between 66.83 and 339.39 mg l(-1), accompanied by media pH decrease. Three isolates, PP14, PP17, and RL90, synthesized indole acetic acid, while PE66 and PE85 could hydrolyze ACC. All isolates produced siderophores and hydrogen cyanide except RL90 and PP17. For extracellular hydrolytic enzymes production, RL90 was positive for cellulase and protease. All isolates suppressed at less one phytopathogenic fungus growth, while the best bacterial phytopathogens inhibition was obtained for PE85. (C) 2019 Elsevier Ltd. All rights reserved.
