Electrochemical stimulation of microbial perchlorate reduction.
As part of our studies into the diversity of dissimilatory perchlorate reducing bacteria (DPRB) we investigated the reduction of perchlorate in the cathodic chamber of a bioelectrical reactor (BER). Our results demonstrated that washed cells of Dechloromonas and Azospira species readily reduced 90 mg L(-1) perchlorate in the BER with 2,6-anthraquinone disulfonate (AQDS) as a mediator. No perchl...
متن کاملELECTROCHEMICAL BEHAVIOUR OF U(V1) NITRATE IN CHLOROFORM AT A MERCURY ELECTRODE THE DEPENDENCE ON SUPPORTING ELECTROLYTE
The mechanistic aspects of the electrochemical reduction of U(V1) nitrate at a mercury electrode in chloroform, using three different supporting electrolytes, are described. In the presence of tetrabutylarnmonium perchlorate (TBAP) as a neutral electrolyte, UO (NO ) , reduced in two irreversible electrochemical steps to form a U(V1)-U(V) binuclear complex and U(IV), respectively. In the pr...
متن کاملReduction of perchlorate and nitrate by microbial communities in vadose soil.
Perchlorate contamination is a concern because of the increasing frequency of its detection in soils and groundwater and its presumed inhibitory effect on human thyroid hormone production. Although significant perchlorate contamination occurs in the vadose (unsaturated) zone, little is known about perchlorate biodegradation potential by indigenous microorganisms in these soils. We measured the ...
متن کاملOn the stability of perchlorate ions against reductive attacks in electrochemical systems and in the environment
The problems related to the electrochemical/electrocatalytic stability of perchlorate ions are reviewed in the light of recent experimental results. The electrocatalytic, catalytic, and electrochemical reduction processes are presented and the links between them are outlined. Some possible mechanisms of the complicated reduction processes are discussed. Various methods for the detection of redu...
متن کاملEnvironmental factors that control microbial perchlorate reduction.
As part of a study to elucidate the environmental parameters that control microbial perchlorate respiration, we investigated the reduction of perchlorate by the dissimilatory perchlorate reducer Dechlorosoma suillum under a diverse set of environmental conditions. Our results demonstrated that perchlorate reduction by D. suillum only occurred under anaerobic conditions in the presence of perchl...
