(+) positive (−) negative test, AP (ammonia production), SH (starch hydrolase), HCN (hydrogen cyanide production), PHS (phosphate solubilization), IAA (indole acetic Acid production), SDP (siderophore production %). Data are average values of three replicates for each bacterial isolate. (±) standard error values.
