  • Isolation and characterisation of phosphate solubilising

    2008-07-27· Amongst the isolates with high efficiency for tricalcium phosphate (TCP) solubilisation, seven bacterial and seven fungal isolates dissolved higher amount of P from North Carolina rock phosphate (NCRP) than Mussoorie rock phosphate (MRP) and Udaipur rock phosphate (URP). However, the organisms solubilised higher-P in NBRIP broth than PVK broth.

  • 4 Facts About Phosphate, the Chemical Compound That's

    2020-10-07· A huge phosphate quarry in Sehnde, Germany, where large deposits were discovered at the end of the 19th century. DeAgostini/Getty Images. It's very likely that at this point in your life, you've heard about the chemical element phosphorus. It's arguably one of the more famous, and with good reason: It's the 11th most common element on Earth, and the second most common in the human

  • Radioactivity and heavy metal composition of Nigerian

    Phosphate rock samples collected from the Dange Formation within the Sokoto basin were analyzed for trace element constituents using instrumental neutron activation analysis (INAA) and X-ray fluorescence analysis (XRFA) techniques, while natural activity concentrations due to 235U, 232Th, and 40K were determined by gamma-ray spectrometry. The analytical results show that the average

  • Acidulated activation of phosphate rock enhances release

    Phosphate rock (PR) was activated via acidulation with HCl, EDTA, and oxalic acid to enhance its reactivity. The release, lateral transport, and uptake of phosphorus (P) along with trace metals from pristine and activated PRs were investigated in a soil micro-block system over a period of 27 days, using wheat (Triticum aestivum L.) plants.. Significantly (p < 0.05) higher amounts of available

  • Enhanced Phosphorus Release from Phosphate Rock Activated

    in effective P ratio directly from raw phosphate rock (PR) powder by mechanical grinding to increase its microcrystallinity is believed to be the best choice for this purpose. This study reports the improvement in the activation property of PR powder with different lignite ratios (1%, 2%, 3%, and 5%), particularly the relationship between particle-size distribution, specific surface area

  • A Fed-Batch Strategy Integrated with Mechanical Activation

    Here, we propose a fed-batch strategy coupled with mechanical activation to improve the biological solubilization of PR by Aspergillus niger. An initial systematic study of the effect of the particle size of Itafós phosphate rock (IPR), a low reactivity phosphate mineral (P2O5, 20%), on the biological solubilization of phosphorus revealed that the particle size played a key role in IPR
