Evaluation of Silicate Minerals for pH Control During Bioremediation: Application to Chlorinated Solvents [PDF]

, 2018
Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. This study evaluated a novel approach for buffering subsurface pH that relies on the use of silicate minerals as a long-term source of ...

Genomic determinants of organohalide-respiration in Geobacter lovleyi, an unusual member of the Geobacteraceae [PDF]

, 2012
Background Geobacter lovleyi is a unique member of the Geobacteraceae because strains of this species share the ability to couple tetrachloroethene (PCE) reductive dechlorination to cis-1,2-dichloroethene (cis-DCE) with energy conservation and growth (i ...

Synergetic Interactions of Nanoscale Zero-Valent Iron (nZVI) and Anaerobic Bacteria in Groundwater Remediation: A Review

Eurasian Journal of Science and Engineering, 2022
During the last century, large scale production of halogenated organic compounds and heavy metals, specifically by industrial processes, and the inappropriate management of those products caused a wide spreading of a variety of hazardous contaminants ...

Uneven distribution of cobamide biosynthesis and dependence in bacteria predicted by comparative genomics. [PDF]

, 2019
The vitamin B12 family of cofactors known as cobamides are essential for a variety of microbial metabolisms. We used comparative genomics of 11,000 bacterial species to analyze the extent and distribution of cobamide production and use across bacteria ...

Validation of an integrative methodology to assess and monitor reductive dechlorination of chlorinated ethenes in contaminated aquifers

Frontiers in Environmental Science, 2016
Bioremediation of tetra-and trichloroethene-contaminated aquifers is frequently hampered due to incomplete dechlorination to the more toxic dichloroethene (DCE) and vinyl chloride (VC), indicating insufficient knowledge about the biological mechanisms ...

Localized Plasticity in the Streamlined Genomes of Vinyl Chloride Respiring Dehalococcoides [PDF]

, 2009
Vinyl chloride (VC) is a human carcinogen and widespread priority pollutant. Here we report the first, to our knowledge, complete genome sequences of microorganisms able to respire VC, Dehalococcoides sp. strains VS and BAV1.

Synergistic mechanism of modified nZVI and Citrobacter reshaping sludge microbiome drives co-removal of HBCD and nutrients in municipal wastewater

Environmental Chemistry and Ecotoxicology
Hexabromocyclododecane (HBCD), a persistent and toxic brominated flame retardant, poses severe ecological and health risks due to its bioaccumulation and endocrine-disrupting effects.

Multiple Dual C−Cl Isotope Patterns Associated with Reductive Dechlorination of Tetrachloroethene [PDF]

, 2017
Dual isotope slopes are increasingly used to identify transformation pathways of contaminants. We investigated if reductive dechlorination of tetrachloroethene (PCE) by consortia containing bacteria with different reductive dehalogenases (rdhA) genes can
