• HAIX removed 90% of the PO 4 -P for 430 BV at 5 min EBCT. 26% COD but it resulted in progressive fouling resin. A regeneration with NaCl 5% is needed to maintain high adsorption capacity. NaOH 2% can be used as regenerant solution eight consecutive times. Around 95% P was recovered from saturated hydroxyapatite. Orthophosphate (PO -P) removal and recovery municipal wastewater were investigate...

Gluconeogenesis is a fundamental metabolic process that allows organisms to make sugars from non-carbohydrate stores such as lipids and protein. In eukaryotes only one gluconeogenic route has been described from organic acid intermediates and this relies on the enzyme phosphoenolpyruvate carboxykinase (PCK). Here we show that two routes exist in Arabidopsis, and that the second uses pyruvate, o...

Dissolved organic matter (DOM) is a complex mixture of carbon-containing compounds. The low-molecular weight (LMW) fraction constitutes thousands different compounds and represents substantial proportion DOM in aquatic ecosystems. turnover rates this LMW can be extremely high. Due to the challenges measuring pool at molecular scale, comparatively little known fate lotic systems. This study addr...

A new eulytite-like orthophosphate Pb(3)Bi(PO(4))(3), was synthesized by the high temperature solution growth (HTSG) method and characterized by X-ray single crystal diffraction, powder diffraction and electron microscopy. It crystallizes in the acentric cubic space group (I4[combining macron]3d). The pure-phase powders of Pb(3)Bi(PO(4))(3), Ba(3)La(PO(4))(3) and Ba(3)Bi(PO(4))(3) were also pre...

Abstract Aim Organic substances in leaves of several southwest Australian native species interfere with sensitive colorimetric assays and prevent quantification inorganic phosphate concentration ([Pi]). We aimed to develop a reproducible routine procedure for treating leaf extracts activated charcoal (AC) remove interfering substances, allowing the determination [Pi] by malachite green spectrop...

The physiological responses of silicate-based bioactive glasses (BGs) are known to depend critically on both the P content (n(P)) of the glass and its silicate network connectivity (N(BO)(Si)). However, while the bioactivity generally displays a nonmonotonic dependence on nP itself, recent work suggest that it is merely the net orthophosphate content that directly links to the bioactivity. We e...

1. A mathematical model is presented for photosynthetic carbohydrate formation in C3 plants under conditions of light and carbon dioxide saturation. The model considers reactions of the Calvin cycle with triose phosphate export and starch production as main output processes, and treats concentrations of NADPH, NAD+, CO2, and H+ as fixed parameters of the system. Using equilibrium approximations...
