It is less than 7 years since perchlorate, a predominantly man-made toxic anion, was first identified as a significant water contaminant throughout the United States. Owing to its solubility and non-reactivity, bioremediation was targeted as the most promising solution for the problem of perchlorate contamination. Since 1996, concerted efforts have resulted in significant advances in our understanding of the microbiology, biochemistry and genetics of the microorganisms that are capable of… Expand

The Microbiology of Perchlorate Reduction and its Bioremediative Application
The field of microbial perchlorate reduction has clearly advanced significantly in a very short period from a poorly understood metabolism to a burgeoning scientific field of discovery. As outlined… Expand
Bioelectrical Perchlorate Reduction and Characterization of Novel Dissimilatory Perchlorate Reducing Bacteria
Perchlorate (ClO4-) is a soluble anion that occurs naturally in small concentrations, however, as a widely used oxidant in solid munitions, it has become a significant contaminant in ground water… Expand
Engineered Intrinsic Bioremediation of Ammonium Perchlorate in Groundwater
Abstract : A variety of perchlorate remediation technologies are currently commercially available. One of them, biological degradation involves perchlorate reducing bacteria (PRBs), which are… Expand
Chemolithotrophic perchlorate reduction linked to the oxidation of elemental sulfur
TLDR
This research investigated the feasibility of utilizing elemental sulfur (S0) as an insoluble electron donor for the biological reduction of perchlorate and obtained a chemolithotrophic enrichment culture derived from aerobic activated sludge which effectively coupled the oxidation of elemental sulfur to sulfate with the reduction ofperchlorate to chloride and gained energy from the process for cell growth.

Microbial Degradation of Perchlorate: Principles and Applications
Perchlorate (ClO4-) release into the environment has occurred primarily in association with its manufacture and use in solid rocket propellant. When released into groundwater, perchlorate can spread… Expand
Biological treatment of ammonium perchlorate-contaminated wastewater: a review
Absolute reduction of perchlorate has proven complex owing to the diverse characteristics of the perchlorate ion. Technologies such as chemical reduction, ozone/peroxide, nanofiltration, and reverse… Expand
Field Demonstration of a Novel Biotreatment Process for Perchlorate Reduction in Groundwater
Abstract : A technology demonstration was conducted at the Well #2 in Rialto, California to treat perchlorate contaminated groundwater using a novel biological treatment system. The new treatment… Expand
Breathing Perchlorate
TLDR
On page 85 of this issue, Liebensteiner et al. show that the hyperthermophilic archaeon Archaeoglobus fulgidus can also respire with perchlorate and chlorate, a discovery that changes several paradigms about per chlorate-reducing microorganisms. Expand
Characterization of an anaerobic marine microbial community exposed to combined fluxes of perchlorate and salinity
TLDR
This work investigates the temporal evolving structure of perchlorate respiring communities under a range of NaCl concentrations using marine sediment amended with acetate and per chlorate to identify the intrinsic capacity of marine systems to respire perchlorates and significantly expand the known diversity of organisms capable of this novel metabolism.

Adapting a denitrifying biocathode for perchlorate reduction.
TLDR
Tests strongly suggest PCRB are utilizing the cathode as an electron donor without exogenous electron shuttles, as a means to confirm the existence of biocathode-utilizing PCRB and the possibility of perchlorate remediation without addedshuttles. Expand

Chlorine isotope fractionation during microbial reduction of perchlorate.
TLDR
Chlorine isotope fractionation during perchlorate biodegradation by a common per chlorate-reducing bacterium, Dechlorosoma suillum, initially isolated from a perchlorATE-contaminated groundwater source in southern California indicates that chlorine isotope analysis provides a sensitive technique by which to document in situ bioremediation of perchlorates in groundwater.
