Plants inoculated with arbuscular mycorrhizal (AM) fungi utilize more soluble phosphorus from soil mineral phosphate than noninoculated plants. However, there is no information on the response of soil microflora to mineral phosphate weathering by AM fungi and, in particular, on the catabolic diversity of soil microbial communities. The AM fungus, Glomus intraradices was examined for (i) its eff...

A mineral phosphate solubilizing bacterium, Burkholderia cepacia DA23 has been isolated from cultivated soils. Phosphate-solubilizing activities of the strain against three types of insoluble phosphate were quantitatively determined. When 3% of glucose concentration was used for carbon source, the strain had a marked mineral phosphate-solubilizing activity. Mineral phosphate solubilization was ...

objective: furcal perforation is an undesirable complication that may occur during root canal therapy and seriously compromises the prognosis of endodontic treatment. the prognosis of furcal perforation repair depends on the prevention of bacterial infection of the perforation site. thus, use of a biocompatible material for complete sealing of the perforation site is critically important. this ...

The mode of succinate mediated repression of mineral phosphate solubilization and the role of repressor in suppressing phosphate solubilization phenotype of two free-living nitrogen fixing Klebsiella pneumoniae strains was studied. Organic acid mediated mineral phosphate solubilization phenotype of oxalic acid producing Klebsiella pneumoniae SM6 and SM11 were transcriptionally repressed by IclR...

General comments in relation to bone mineral metabolism: • In Stage 5 kidney disease, serum phosphate, serum calcium, calcium x phosphate product and parathyroid hormone (PTH) level need to be considered simultaneously when assessing the bone mineral status of a patient: a combination of high calcium, high phosphate and low PTH level being associated with the worst outcome. (Level III evidence ...

BACKGROUND Recent studies in humans suggest that ferritin iron in soybeans has high bioavailability. However, direct evidence for this is lacking because the soybeans were intrinsically labeled; thus, iron bound to other ligands, such as phytate, was also labeled. OBJECTIVE The objectives of the study were to evaluate the absorption of iron from extrinsically labeled, purified ferritin (horse...

We provide evidence that citrate anions bridge between mineral platelets in bone and hypothesize that their presence acts to maintain separate platelets with disordered regions between them rather than gradual transformations into larger, more ordered blocks of mineral. To assess this hypothesis, we take as a model for a citrate bridging between layers of calcium phosphate mineral a double salt...

The use of phosphate solubilizing bacteria as inoculants simultaneously increases P uptake by the plant and crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium are among the most powerful phosphate solubilizers. The principal mechanism for mineral phosphate solubilization is the production of organic acids, and acid phosphatases play a major role in the mineralization of org...

Ten indigenous bacterial isolates were identified as efficient mineral phosphate solubilisers namely 7 strains of Klebsiella pneumoniae, 2 strains of Enterobacter aerogenes and 1 strain of Pseudomonas aeruginosa. All the ten strains were able to dissolve calcium phosphate (Ca-P), ferric phosphate (Fe-P) and aluminium phosphate (Al-P) efficiently. STMPSB 8 (Klebsiella pneumoniae) could be design...
