Biodegradation of chlorinated ethenes by a methane-utilizing mixed culture [PDF]

Applied and Environmental Microbiology, 1986
Chlorinated ethenes are toxic substances which are widely distributed groundwater contaminants and are persistent in the subsurface environment. Reports on the biodegradation of these compounds under anaerobic conditions which might occur naturally in groundwater show that these substances degrade very slowly, if at all.

Proteomic data set of the organohalide-respiring Epsilonproteobacterium Sulfurospirillum multivorans adapted to tetrachloroethene and other energy substrates

Data in Brief, 2016
Sulfurospirillum multivorans is a free-living, physiologically versatile Epsilonproteobacterium able to couple the reductive dehalogenation of chlorinated and brominated ethenes to growth (organohalide respiration).

Evaluation of the costs of the remediation system using peroxone for the treatment of chlorinated ethenes

Revista Águas Subterrâneas, 2017
The use of Advanced Oxidation Processes for remediation of contaminated areas has become an effective alternative to the destruction of contaminants when applied directly to soil and groundwater or through the treatment systems.

Effect of temperature on microbial reductive dehalogenation of chlorinated ethenes: a review

FEMS Microbiology Ecology, 2022
AbstractTemperature is a key factor affecting microbial activity and ecology. An increase in temperature generally increases rates of microbial processes up to a certain threshold, above which rates decline rapidly. In the subsurface, temperature of groundwater is usually stable and related to the annual average temperature at the surface.

Chlorinated Electron Acceptor Abundance Drives Selection of Dehalococcoides mccartyi (D. mccartyi) Strains in Dechlorinating Enrichment Cultures and Groundwater Environments

Frontiers in Microbiology, 2018
Dehalococcoides mccartyi (D. mccartyi) strains differ primarily from one another by the number and identity of the reductive dehalogenase homologous catalytic subunit A (rdhA) genes within their respective genomes.

Temperature-associated effects on methanogenesis and microbial reductive dechlorination of trichloroethene in contaminated aquifer sediments

Frontiers in Water
BackgroundAquifer thermal energy storage (ATES) is a subsurface technology for urban heating and cooling. However, ATES systems may intersect with legacy groundwater contaminants from past anthropogenic activities.
