Phosphite - an overview | ScienceDirect Topics
Phosphite dehydrogenase catalyzes the NAD +-dependent oxidation of hydrogen phosphonate (common name phosphite) to phosphate in what amounts to a formal phosphoryl transfer reaction from hydride to hydroxide. This review places the enzyme in the context of phosphorus redox metabolism in nature and discusses the results of mechanistic ...
Role of phosphite in the environmental phosphorus cycle
2023年7月10日 · Nevertheless, the phosphite (Phi) form of P is widely present in various environments and participates in the global P redox cycle. Herein, global quantitative evidences of Phi are enumerated and the early origin and modern biotic/abiotic sources of Phi are elaborated.
Organic Phosphite - an overview | ScienceDirect Topics
2012年7月24日 · Phosphite type secondary AOs sometimes have water sensitivity, so there are many different materials offered for each specific polymer and end use. Some of the newer secondary AOs of this class approach or exceed primary AOs in cost, but this is justified by reduction of color and falling cost of some primary AOs.
Biostimulant activity of phosphite in horticulture
2015年11月30日 · Phosphite (Phi), a reduced form of phosphate (Pi), is emerging as a novel biostimulator in horticulture. Though there is still no consensus on its physiological function as a P-source for plant nutrition, experimental evidence has shown that Phi can act as a biocide and affect plant production and productivity.
Microbial Phosphite Oxidation and Its Potential Role in the Global ...
2017年1月1日 · Phosphite (HPO 3 2 −) is a highly soluble, reduced phosphorus compound that is often overlooked in biogeochemical analyses. Although the oxidation of phosphite to phosphate is a highly exergonic process (E o ' = −650 mV), phosphite is kinetically stable and can account for 10–30% of the total dissolved P in various environments. There is ...
Phosphite Ion - an overview | ScienceDirect Topics
The HP(O) 2 (OH) − species is called the hydrogenphosphite, and the HPO 3 2 −, the phosphite ion. (IUPAC recommendations are hydrogenphosphonate and phosphonate, respectively). H-Phosphonic acid is also used for preparing phosphite salts, such as potassium phosphite. 6.1.2 Reactivity of P–H Group6.1.2.1. Addition to Carbonyl Group and ...

Application of phosphite as a biostimulant in agriculture
2022年1月1日 · Phosphite [H 2 PO 3 − or HPO 3 2 (Phi)], an analog of phosphate [H 2 PO 4 − or HPO 4 −2 (Pi)], is gaining relevance as an inorganic biostimulant in agriculture, enhancing the growth, production, and productivity of various crop plants, while promoting better performance in species established in challenging environments. In nature, plants ...
Impacts of phosphite treatment on - ScienceDirect
Phosphite was trialled in infected Quercus ilex forests in Spain through foliar and trunk spray application: the crown condition of unhealthy trees was improved by phosphite application, and there were no effects on the bacterial communities associated with leaves or …
Phosphite - an overview | ScienceDirect Topics
Phosphorus may also be found as phosphite PO 3 3 −, which may be determined as mercurous chloride or ammonium magnesium phosphate. In the first case, an acid solution of phosphite reduces mercury(II) chloride solution (eqn 1), and mercury (I) chloride is weighed, the latter being directly proportional to the phosphite concentration.
