In plant seeds, most of the phosphate is in the form of phytic acid. Phytic acid is largely indigestible by monogastric animals and is the single most important factor hindering the uptake of a range of minerals. Engineering crop plants to produce a heterologous phytase improves phosphate bioavailability and reduces phytic acid excretion. This reduces the phosphate load on agricultural ecosyste...

Glucose-6-phosphate dehydrogenase was partially purified from both glucose-grown and iron-glucose-grown Thiobacillus ferrooxidans. The enzyme possesses a dual nucleotide specificity for either nicotinamide adenine dinucleotide phosphate (NADP) or nicotinamide adenine dinucleotide (NAD) and has a molecular weight of 110,000 as determined by gel electrophoresis. Evidence is presented that T. ferr...

The microstructure and chemical composition of iron phosphate conversion coatings were investigated by surface/cross-sectional observation using FE-SEM/STEM state analysis XPS. As a result, it was suggested that the reaction progressed while surface oxide on base material remained, fine particles components deposited agglomerated to cover surface. upper layer mainly composed phosphate, interfac...

Materials and methods: The evaluation consisted of determination of within-run and between-run imprecision, inaccuracy and comparison with Olympus AU2700. The tested analytes were: glucose, creatinine, urate, total bilirubin, cholesterol, tryglicerides, calcium, phosphate, iron, unsaturated iron binding capacity, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creat...

Iron oxide nanoparticles adsorb fluorescently labeled DNA oligonucleotides via the backbone phosphate and quench fluorescence. Arsenate displaces adsorbed DNA to increase fluorescence, allowing detection of arsenate down to 300 nM. This is a new way of using DNA: analyte recognition relies on its phosphate instead of the bases.

This study evaluates the arsenic adsorption behavior of Fe-exchanged smectite and phosphate-bound kaolinite, in soil, tap water double distilled presence competing anions such as silicate, phosphate, sulfate, at variable pH values. The maximum amounts As adsorbed soil are 620.6 607.6 µg g–1 5 by respectively. pH-modified Freundlich equation fits well (R2 > 0.96) to data, distinguishing effect o...

Iron (oxyhydr)oxides participate in a variety of geochemical processes, and hence control the cycling elements quality soils. The present work provides information about macroscopic adsorption behaviors microscopic mechanisms typical cations oxyanions (i.e., cadmium phosphate) on three omnipresent iron ferrihydrite (Fh), goethite (Gt), hematite (Hm)) single- double-solute systems, which can not...
