摘要: In this study, among a collection of Ni-resistant bacterial strains isolated from the rhizosphere Alyssum serpyllifolium and Phleum phleoides grown on serpentine soil, five plant growth-promoting bacteria (PGPB) were selected based their ability to utilize 1-aminocyclopropane-1-carboxylate (ACC) as sole N source promote seedling growth. All tested positive for indole-3-acetic acid (IAA) production phosphate solubilization. addition, four exhibited significant levels siderophores production. Further, efficiency PGPB in enhancing Ni solubilization soils was analyzed. Compared with control treatment, inoculation significantly increased concentrations bioavailable Ni. Furthermore, pot experiment conducted elucidate effects inoculating growth uptake by Brassica juncea B. oxyrrhina soil contaminated 450 mg kg(-1) Psychrobacter sp. SRA2 fresh (351%) dry biomass (285%) test plants (p<0.05), whereas SRA1 Bacillus cereus SRA10 accumulation root shoot tissues compared non-inoculated controls. This result indicates that facilitated release non-soluble phases thus availability plants. A increase, greater than control, also noted parameters when seeds treated strain SRA2. effect can be attributed utilization ACC, IAA. The results study revealed mobilizing increases phytoextraction directly metal efficient PGPB, indirectly promoting oxyrrhina.
