An increase in phosphorus (P) availability through the addition of microbial inoculant, such as phosphate-solubilising bacteria (PSB), in organic agricultural soils, could be a good option for increasing soil fertility. We evaluated phosphate-solubilising (PS) ability and phosphate-mineralising (PM) ability of PSB isolated from organic paddy soils. Total soil bacteria were isolated on LB agar and tested on NBRIP agar for tricalcium phosphate (TCP) solubilisation. Three PSB strains were selected, based on their colonial morphologies on LB agar, for the measurement of PS ability in NBRIP broth, and PM ability in the presence of acid phosphatase substrate, p-nitrophenyl phosphate in culture broth. PSB were identified by morphology and a molecular technique using 16S rRNA gene. The results indicated that the selected PSB were able to solubilise TCP and presented acid phosphatase activity. The TCP solubilisation was performed via acid production in NBRIP broth. The strain Ca-106, which was closely related to Bacillus sp. based on the identity of 16S rRNA gene sequences, presented the TCP solubilisation of 181.57 mg P l-1 which was higher than that in the previous report. The other strains (Ca-203 and Ca-270) solubilised TCP with the values of 195.48 mg P l-1 and 180.46 mg P l-1 respectively. They were closely related to Enterobacter sp., based on the identity of 16S rRNA gene sequences. The activity of extracellular acid phosphatase presented the values of 8.12 µM pNP ml-1 h-1, 7.41 µM pNP ml-1 h-1 and 4.40 µM pNP ml-1 h-1 for the strains Ca-106, Ca-203 and Ca-270, respectively. The high activity of acid phosphatase was observed for the selected PSB when compared to the previous reports that used the same technique. Taken together, the results indicated that all selected PSB had both PS ability via the acidification process and PM ability via the production of extracellular acid phosphatase. They can be potentially applied as microbial inoculants for increasing, especially, organic P mineralisation in organic agricultural soils. Further, the PSB strains merit a further study with a target plant, in pot experiments, in order to verify their ability to promote plant growth.
