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 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...
متن کاملOverturning Established Chemoselectivities: Selective Reduction of Arenes over Malonates and Cyanoacetates by Photoactivated Organic Electron Donors
The prevalence of metal-based reducing reagents, including metals, metal complexes, and metal salts, has produced an empirical order of reactivity that governs our approach to chemical synthesis. However, this reactivity may be influenced by stabilization of transition states, intermediates, and products through substrate-metal bonding. This article reports that in the absence of such stabilizi...
متن کاملMicrobial reduction of perchlorate with zero-valent iron.
Microbial reduction of perchlorate in the presence of zero-valent iron was examined in both batch and column reactors to assess the potential of iron as the electron donor for biological perchlorate reduction process. Iron-supported mixed cultures completely removed 65 mg/L of perchlorate in batch reactors in 8 days. The removal rate was similar to that observed with hydrogen gas (5%) and aceta...
