“…Plants face several challenges in acidic soils, primarily related to the availability of essential nutrients. One of the main issues is the soil’s reduced capacity to retain and supply important nutrients for plant growth, such as phosphorus [ 5 ]. This element is one of the most-required nutrients by plants (second only to nitrogen), being a fundamental component of nucleic acids (RNA and DNA), phospholipids (forming cell membranes), and adenosine triphosphate (ATP), as well as playing a key role in processes such as respiration and photosynthesis [ 6 ].…”

Due to its adsorption with aluminum and iron hydroxides, phosphorus viability is low in acidic soils; thus, the aim of this study was to isolate and identify bacteria from the rhizosphere of four legumes growing in acidic soils of the Cumbaza Sub-basin, San Martín, Peru, as well as to characterize their ability to solubilize aluminum phosphate and iron phosphate. The isolation process was conducted on TSA medium and the isolates were classified based on their origin and morphocolonial characteristics, with the bacillary shape being the most frequent, followed by cocci. To assess the solubilization of aluminum and iron phosphates, the liquid medium GELP was employed. Sixteen strains were selected, among which three stood out for their effectiveness in solubilizing AlPO4 (Sfcv-098-02, 22.65 mg L−1; Sfc-093-04, 26.50 mg L−1; and Sfcv-041-01-2, 55.98 mg L−1) and one for its ability to solubilize FePO4 (Sfcr-043-02, 32.61 mg L−1). These four strains were molecularly characterized, being identified as Enterobacter sp., Pseudomonas sp., and Staphylococcus sp. Additionally, a decrease in pH was observed in the reactions, with values ranging from 5.23 to 3.29, which enhanced the phosphate of solubilization. This suggests that the selected bacteria could be used to improve phosphorus availability in agricultural soils.
