In aquatic environments, phosphorus is known as the “limiting nutrient.” It combines with nitrogen and photosynthetic processes to produce plant and algal growth. Phosphorus in marine life support systems exists in either a particulate or dissolved phase. While particulate sources may be removed during filtration or fractionation, the dissolved form persists. In a typical marine environment (pH...

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 phosphate uptake medium ...

there is a distinct possibility that phytate negatively influences protein and energy utilisation in poultry and, as these influences would be ameliorated by phytase, there are substantial, practical implications. despite several thousand scientific papers and a rapidly growing market the use of phytase and the importance of phytate in practical poultry nutrition remains an area of some confusi...

In the present study, struvite decomposition was performed by air stripping for ammonia release and a novel integrated reactor was designed for the simultaneous removal and recovery of total ammonia-nitrogen (TAN) and total orthophosphate (PT) from swine wastewater by internal struvite recycling. Decomposition of struvite by air stripping was found to be feasible. Without supplementation with a...
