After equilibrating cells with [32P]phosphate there were 3.7 f 0.2 mol of [32P]phosphate/mol of Band 2 subunit; this is the total measured as nonradioactive phosphate in fresh cells (Harris, H. W., Wolfe, L. C., and Lux, S . E. (1978) Fed Roc. 37, 1507). This level can be reduced in intact cells by metabolic depletion, or on purified spectrin by tryptic removal of the terminal phosphorylated pe...

The element phosphorus (P) is essential to all life (e.g. plants, animals and bacteria) and is a key ingredient in fertilizers to sustain high crop yields. However, the lifetime of exploitable reserves of natural ore deposits containing P is estimated to range from the next few decades to several hundreds of years, since P is intensively used in agriculture and other industries. The use of P yi...

Efforts to reduce phosphorus concentrations in aquaculture systems have mainly dealt with improving the bioavailability of phosphorus in fish feed. Once released into the culture water, phosphorus is generally left untreated and discharged with the effluent water. In the present study, results are presented on a prototype recirculating treatment system originally designed for removal of organic...

Mango stone biocomposite efficiency for the removal of phosphate ions (PO4) from aqueous solution was investigated as a function of pH (2–8), biocomposite dose (0.05–0.40 g/100 mL solution), contact time (5–120 min), initial PO4 ions concentration (20–800 mg/L) and temperature (33–61 C). Maximum PO4 ions removal was achieved at pH 2, biocomposite dose 0.3 g, contact time 90 min and initial PO4 ...

Inorganic polyphosphates (PolyP) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. Four isolates had been screened from soil sample. By MALDI-TOF analysis, they were identified as Bacillius cereus, Acinetobacter towneri, B. megaterium and B. cereus. The production of PolyP in four isolates was studied in phosph...

Phosphate removal is both biologically and environmentally important. Biologically, hyperphosphatemia is a critical condition in end-stage chronic kidney disease patients. Patients with hyperphosphatemia are treated long-term with oral phosphate binders to prevent phosphate absorption to the body by capturing phosphate in the gastrointestinal (GI) tract followed by fecal excretion. Environmenta...

Candidatus Accumulibacter phosphatis (Accumulibacter), which plays an important role in enhanced biological phosphorus removal in wastewater treatment plants, is phylogenetically classified into two major types (Types I and II). Phosphate concentrations affect the Accumulibacter community of the biomass enriched in treatment plants. Therefore, in the present study, Accumulibacter enrichments we...

An elderly woman developed severe hyperphosphataemia, hypocalcaemia, and cardiac arrest after oral administration of sodium phosphate in preparation for colonoscopy. This is an unusual complication and is attributed to decreased phosphate excretion by the kidneys. At increased risk are patients with impaired renal function, age more than 65 years, and presenting with intestinal obstruction or d...
