The objective of the study was to evaluate the iron bioavailability of iron amino acid complex, Availa-Fe compound, as compared to the iron from feed grade ferrous sulfate in weanling piglets. Seventy-two 30-day-old three-way cross piglets, with an average live-weight of 6.41 kg, were randomly allocated into 12 groups of six dietary treatments and two replicates. The control diet (C) included 1...

Ten indigenous bacterial isolates were identified as efficient mineral phosphate solubilisers namely 7 strains of Klebsiella pneumoniae, 2 strains of Enterobacter aerogenes and 1 strain of Pseudomonas aeruginosa. All the ten strains were able to dissolve calcium phosphate (Ca-P), ferric phosphate (Fe-P) and aluminium phosphate (Al-P) efficiently. STMPSB 8 (Klebsiella pneumoniae) could be design...

We conducted a study to determine the seasonal relationship between iron, sulfur, and phosphorus in the upper sediments and pore waters of a shallow intercoastal bay. From April 1999 to September 2000, sediment cores were collected from Rehoboth Bay, Delaware. Analyses of the sediments in the upper 4 cm revealed that redox conditions controlled Fe-S-P concentrations in the sediments, pore water...

Iron (Fe) loaded solid lipid nanoparticles (SLN's) were formulated using stearic acid and iron absorption was evaluated in vitro using the cell line Caco-2 with intracellular ferritin formation as a marker of iron absorption. Iron loading was optimised at 1% Fe (w/w) lipid since an inverse relation was observed between initial iron concentration and SLN iron incorporation efficiency. Chitosan (...

this research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. applied nutrients were zinc sulphate (zn) of 0.0 and 1.5gl-1 and urea (n) at 0.0 and 5 gl-1 and fe (1) control (low fe)...

Numerous cellular functions including respiration require iron. Plants and phytoplankton must also maintain the iron-rich photosynthetic electron transport chain, which most likely evolved in the iron-replete reducing environments of the Proterozoic ocean [1]. Iron bioavailability has drastically decreased in the contemporary ocean [1], most likely selecting for the evolution of efficient iron ...

The electrochemical behavior of passive Fe and thin, sputter-deposited films of Fe2O3 was studied in borate and phosphate buffer pH 8.4 solutions. Cyclic voltammograms and in situ light absorption measurements which enable the monitoring of the oxide film thickness indicate a similar behavior of the Fe electrode in both pH 8.4 solution, especially a presence of a oxide-free surface at low catho...

In this study, enrichment possibility of apatite-bearing iron ore sample was investigated to obtain and phosphate concentrates, separately. It determined that the raw contains 35.75% Fe 5.36 P2O5. Magnetite from can be enriched with low field strength wet magnetic separators, apatite magnetite residues by flotation. For purpose, ground minus 106 m size then subjected separation following Accor...

A study of the reactions of ferroporphyrins, in the presence of an excess of a reducing agent, with various polyhalogenated compounds, has led to a general method of preparation of iron-carbene complexes, Fe(porphyrin) (CRR') . It has thus been possible to obtain iron complexes of the dihalogenocarbenes CC12, CBr2, CF2, CFBr and CFC1, which are thermally stable (up to 100°C) and not dissociated...

The influence of calcium supplements on the absorption of dietary nonheme iron and of iron supplements was evaluated in 6 1 normal volunteer subjects by use ofa doubleradioisotope technique. When taken without food, calcium carbonate did not inhibit the absorption of ferrous sulphate with doses of either 300 mg Ca and 37 mg Fe or 600 mg Ca and 18 mg Fe. However, at the latter levels, calcium ci...
