Resumen
This study tested the solubilization of phosphorus by five actinobacterial strains in liquid media containing Ca 3 PO 4 ; AlPO 4 or FePO 4 as the sole phosphate source, and discusses the possible mechanisms involved in this process. P solubilization by different strains was accompanied by a significant drop in pH from 7.0 to 2.15–5.0 after 14 days. The efficiency of different strains depended on the P-source. Streptomyces spp. MM140 and MM141 were the most efficient in solubilizing Ca 3 PO 4 , MM136, and MM141 were the most efficient in solubilizing AlPO 4 , while all strains were equally efficient in solubilizing FePO 4 . Gluconic, oxalic, citric, malic, succinic, formic, and acetic acid were detected in the medium with Ca 3 PO 4 , while all except acetic acid were detected in the media with FePO 4 or AlPO 4 . Although we did not use an organic source of phosphorus in the media, all strains produced acid and alkaline phosphatase. It is concluded from this study that actinobacteria produced multiple organic acids followed by a decrease in the pH to solubilize phosphate salts. As well as producing phosphatase, these microorganisms were found to have different ways of making P available, suggesting an ecological advantage as they form part of soil microbiomes important for plants.
