Phenazine methosulfate was shown to be a competitive inhibitor of H+ in light-induced H+ transport as well as a competitive inhibitor of orthophosphate in photophosphorylation. Similarly, H+, NH4+, and Pi in the presence of adenosine diphosphate were shown to inhibit competitively light-induced binding of phenazine methosulfate to chloroplasts. Pi, in the absence of ADP or other anions such as ...

Nutrient availability plays a crucial role in microalgae growth domestic wastewater. In this study, we investigated the impact of different nitrogen and phosphorus ratios (5:1, 10:1, 20:1, m∙m−1), addition inorganic carbon on nutrient uptake from Microalgae biomass achieved values ranging 0.54 to 1.41 g·L−1. The cultivation process had maximum removal efficiencies 83.7% for soluble chemical oxy...

A field experiment was conducted at Bangladesh Agricultural Research Institute (BARI) farm, Gazipur to evaluate the effect of foliar application of potassium orthophosphate on grain yield and kernel quality of wheat under the terminal heat stress imposed by late sowing for two consecutive years (2008-09 and 2009-10). Five combinations of foliar applications of potassium orthophosphate and Tilt ...

The tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) caused a marked stimulation of inorganic [32P]orthophosphate incorporation into HeLa-cell phosphatidylcholine (PC), phosphatidylethanolamine (PE), and lysophosphatidylethanolamine. The increased incorporation of inorganic [32P]orthophosphate into PE and lysophosphatidylethanolamine in the presence of TPA was not associated with an in...

Water quality data at 12 sites within an urban, a suburban, and a rural stream were collected contemporaneously during four wet and eight dry periods. The urban stream yielded the highest biochemical oxygen demand (BOD), orthophosphate, total suspended sediment (TSS), and surfactant concentrations, while the most rural stream yielded the highest total organic carbon concentrations. Percent wate...

A procedrue is described for the preparation of [32P]phosphatidyl-CMP(CDP-diacylglycerol) from rat pineal glands incubated with [32P]orthophosphate and DL-propranolol. The product is 95% radiopure and a high specific acitivity. The yield of liponucleotide is 0.4--0.9 micron Ci/mCi of [32P]orthophosphate in the medium. The same method can also be used for the biosynthesis and purification of [3H...

Simultaneous ammonium–nitrogen (NH₄⁺–N) removal and orthophosphate–phosphorus (PO₄–P) biomineralization was studied in two granular sludge sequencing batch reactors treating urban sidestream centrate through the one-stage partial nitritation–anaerobic ammonium oxidation (anammox) process. By adding an external source of calcium, concomitant conversion rates up to 0.32 g NH₄⁺–N/(L·days) 12 mg PO...

Phosphorus (P) can leach from topsoil in inorganic and organic forms. While some evidence has shown P (orthophosphate) to depth soils, less is known of dissolved (DOP). This not helped by a paucity DOP data for groundwater. We hypothesized that species would greater amounts at faster rate through aquifer gravels than orthophosphate. applied superphosphate with or without dung low P-sorption soi...

Organic phosphorus (P) fractions in surface sediments from a large shallow, eutrophic Lake Taihu, China, were extracted with 0.1 M NaOH after pre-treatment of the sediments with a solution composed of 0.1 M EDTA and 2% (w/v) Na(2)S(2)O(4). Composition of organic P in the extracts was then characterized by (31)P nuclear magnetic resonance spectroscopy ((31)P NMR). Several P species, including ph...
