Perchlorate Removal by Perchlorate Reducing Bacteria Consortium in a Continuous Bioreactor

Quantitative detection of perchlorate-reducing bacteria by real-time PCR targeting the perchlorate reductase gene.

A quantitative real-time PCR assay targeting the pcrA gene, encoding the catalytic subunit of perchlorate reductase, detected pcrA genes from perchlorate-reducing bacteria in three different genera and from soil microbial communities. Partial pcrA sequences indicated differences in the composition of perchlorate-reducing bacterial communities following exposure to different electron donors.

Commercial interest in perchlorates began in the late 1890s/early 1900s in Europe and the United States as a direct result of the pioneering efforts in rockets and their propulsion systems (Mendiratta et al. 1996). The production of ammonium perchlorate, the largest component of solid rocket propellants, far outpaced that of the other perchlorates listed in Table 4-1. Their commercial manufactu...

Perchlorate Reduction In A Packed Bed Bioreactor Using Elemental Sulfur

This study investigated perchlorate reduction by sulfur utilizing perchlorate reducing bacteria (SUPeRB). SUPeRB cultures were enriched from a denitrifying wastewater inoculum in medium containing elemental sulfur (S), crushed oyster shell, nutrients and perchlorate. Perchlorate was reduced from 5 to < 0.5 mg/L in approximately 15 days. The enrichment culture was subsequently inoculated into a ...

Growth and Survival of Perchlorate-reducing Bacteria in Media Containing Elevated Perchlorate Concentrations and Uv-c Conditions

Introduction: The identification of perchlorate (ClO4) on Mars [1,2] has led to the possibility that complete redox couples are available for microbial metabolism in contemporary surface environments [3]. Perchlorate-reducing bacteria (PRB) utilize ClO4 and chlorate (ClO3) as terminal electron acceptors due to the high reduction potential [3]. Additionally, ClO4 salts have been suggested as a p...
