Extraction of arsenate and arsenite species from soils and sediments.
The primary objective of this study was to develop a simple method that can be used to extract the more readily mobilizable and bioavailable arsenic species from soil and sediment while at the same time minimizing the transformation between (AsIII) and (AsV), the two most commonly found arsenic species in the environment. Several extraction strategies were evaluated using phosphate as extractan...
متن کاملArsenite oxidation and arsenate respiration by a new Thermus isolate.
A new microbial strain was isolated from an arsenic-rich terrestrial geothermal environment. The isolate, designated HR13, was identified as a Thermus species based on 16S rDNA phylogenetic relationships and close sequence similarity within the Thermus genus. Under aerobic conditions, Thermus HR13 was capable of rapidly oxidizing inorganic As(III) to As(V). As(III) was oxidized at a rate approx...
متن کاملOxidation of arsenite to arsenate by Alcaligenes faecalis.
Alcaligenes faecalis, resistant to the toxic effects of 0.01 M sodium arsenite, was isolated from raw sewage and shown to be capable of oxidizing arsenite to arsenate. When the organisms were grown in chemically defined medium, this conversion was due to the appearance at stationary phase of an intracellular, oxygen-sensitive, inducible enzyme and/or component of the electron transport system; ...
متن کاملCoexisting arsenate and arsenite adsorption from water using porous pellet adsorbent: Optimization by response surface methodology
Mesoporous pellet adsorbent developed from mixing at an appropriate ratio of natural clay, iron oxide, iron powder, and rice bran was used to investigate the optimization process of batch adsorption parameters for treating aqueous solution coexisting with arsenate and arsenite. Central composite design under response surface methodology was applied for optimizing and observing both individual a...
متن کاملArrangement of human erythrocyte membrane proteins.
The orientation of human erythrocyte membrane protein was examined by enzymic iodination using lactoperoxidase with the glucose-oxidase system for generating peroxide, followed by proteolytic digestion. The outer surface of intact cells was labeled with 125I and the cytoplasmic surface of either resealed ghosts containing lactoperoxidase or of inside-out vesicles was labeled with 131I. Followin...
