“…B. cereus is known for food poisoning, ocular infections, and pneumonia with other sites sometimes affected (Tuazon, 1995). Rikken et al (1996) reported that perchlorate and chlorate are reduced to chloride by Proteobacteria with acetate as a nutrient (reductant) at near-neutral pH. While they did show loss of perchlorate and chlorate, their mechanisms failed to include contributions from uncatalyzed reactions.…”

Abstract:Since the discovery of perchlorate in the ground and surface waters of several western states, there has been increasing interest in the health effects resulting from chronic exposure to low (parts per billion [ppb]) levels. With this concern has come a need to investigate technologies that might be used to remediate contaminated sites or to treat contaminated water to make it safe for drinking. Possible technologies include physical separation (precipitation, anion exchange, reverse osmosis, and electrodialysis), chemical and electrochemical reduction, and biological or biochemical reduction. A fairly unique combination of chemical and physical properties of perchlorate poses challenges to its analysis and reduction in the environment or in drinking water. The implications of these properties are discussed in terms of remediative or treatment strategies. Recent developments are also covered.

“…Perchlorate-reducing organisms couple the oxidization of an organic or inorganic electron donor to the reduction of perchlorate in a form of anaerobic respiration (29). Various organic electron donors, including ethanol, fatty acids (e.g., acetate, lactate, propionate, and citrate), vegetable oils, and molasses support this metabolism.…”

Biological reactors currently treat nearly 30 million liters of perchlorate-contaminated groundwater per day, and in situ treatment techniques are now showing success at the field scale. PAUL B. H ATZINGER SHAW ENV IRONMENTAL, INC. ment of Health Services (DHS) developed an improved analytical technique that reduced the minimum reporting level (MRL) for the anion in water from ~400 to 4 µg/L. Subsequent drinking-water testing performed throughout California revealed contamination in several regions of the state, including Los Angeles, San Bernardino, Riverside, Orange, and Sacramento counties. As of December 2004, 361 out of ~6800 public drinking-water sources in California have tested positive for perchlorate (1). Numerous private wells are also tainted. Although California appears to have the most widespread contamination, 34 other states, including Nevada,

Dechloromonas hortensis sp. nov. and strain ASK-1, two novel (per)chlorate-reducing bacteria, and taxonomic description of strain GR-1 Recent studies on the occurrence of (per)chlorate-reducing bacteria have resulted in the characterization of strains capable of dissimilatory (per)chlorate reduction. Phylogenetic analysis has shown that these bacteria are members of the Proteobacteria. Strains have been isolated from polluted and pristine sites, but only strains from polluted sites have been characterized in detail and deposited in culture collections. Herein we describe the isolation and characterization of perchlorate-reducing bacterium strain MA-1 T and chlorate-reducing bacterium strain ASK-1, respectively isolated from a pristine and a chlorate-polluted site. Both isolates are members of the Proteobacteria. The 16S rRNA gene sequence similarity of MA-1 T to Dechloromonas agitata DSM 13637 T is 97?6 %, but the relatedness in DNA-DNA reassociation is only 37 %. Therefore, we propose to classify strain MA-1 T (=DSM 15637 T =ATCC BAA-776 T ) as the type strain of a novel species, Dechloromonas hortensis sp. nov. Strain ASK-1 and a previously described strain GR-1 show 100 and 99 % 16S rRNA gene sequence similarity to Pseudomonas chloritidismutans DSM 13592 T and Dechlorosoma suillum DSM 13638 T , respectively. DNA-DNA hybridization studies indicated that strains ASK-1 and GR-1 are related at the species level to P. chloritidismutans DSM 13592 T (79 %) and Dechlorosoma suillum DSM 13638 T (85 %), respectively. As suggested previously, Dechlorosoma suillum appears to be a later heterotypic synonym of Azospira oryzae. Although strain ASK-1 is identified as P. chloritidismutans, its morphology and growth requirements are different from those of the type strain.The occurrence of perchlorate and chlorate in natural environments is due mainly to human activities. Chlorate is used as a herbicide, as a catalyst in matches and for onsite production of chlorine dioxide (ClO 2 ), a bleaching agent employed in the paper and pulp industries. Perchlorate is used as rocket propellant in the defence and aerospace industries. In the United States, discharge of perchlorate-containing waste streams has been identified as the major source of perchlorate contamination in drinking water supplies (Renner, 1998; US Environmental Protection Agency, 2000). Chlorate and perchlorate are highly soluble and chemically stable under environmental conditions (Urbansky, 2002). Remediation strategies by chemical reduction or by adsorption to activated carbon are either too slow or incomplete (Urbansky, 1998). Recent research has shown that bioremediation may be the most economically feasible, fastest and easiest means of treating (per)chlorate-contaminated sites and water sources (Coates & Achenbach, 2004). (Per)chlorate-reducing bacteria are able to perform aThe GenBank/EMBL/DDBJ accession numbers of the 16S rRNA gene sequences of strains ASK-1, MA-1 and GR-1 are AY277620, AY277621 and AY277622.Photographs of colonies and cell extracts of P. chl...
