Bacteria producers of plant growth-promoting (PGP) substances are responsible for the enhancement development through several mechanisms. The purpose present work was to evaluate PGP traits 63 bacterial strains that were isolated from an anthropogenic soil, and obtained by modification vertisols in Sicily region (Italy) seven years after creation. microorganisms tested following characteristics: indole acetic acid (IAA), NH3, HCN siderophore production, 1-aminocyclopropane-1-carboxylate deaminase activity (ACC) phosphate solubilization. results principal component analysis (PCA) showed Bacillus tequilensis SI 319, Brevibacterium frigoritolerans 433, Pseudomonas lini 287 frederiksbergensis 307 expressed high levels IAA production ACC enzyme, while rest analyzed best performances registered with genus, particular atacamensis 443, reinekei 441 granadensis 422 450. vitro screening provided enough evidence future vivo growth promotion tests these eight strains.
