Phenotypic and genomic characterization of phosphate-solubilizing rhizobia isolated from native Mimosa and Desmodium in Brazil.

ABSTRACT: The phosphate (P)-solubilizing potential of rhizobia isolated from active root nodules of Brazilian native Mimosa and Desmodium was assessed. Out of the 15 strains selected, five Paraburkholderia isolated from Mimosa spp. grown in rocky outcrops stood out. The Ca₃(PO₄)₂-solubilizing efficiency of these strains ranged from 110.67 to 356.3 mgL^-1, with less expressive results for FePO₄ and Al(H₂PO₄)_3, that might be attributed to the low solubility of these two P compounds. Paraburkholderia strains CNPSo 3281 and CNPSo 3076 were the most efficient siderophore producers (44.17 and 41.87 µMol EDTA) and two of the top FePO₄ solubilizers. Acidification of the culture media was observed for all the st
