A study of chlorinated solvent contamination of the aquifers of an industrial area in central Italy: a possibility of bioremediation

Frontiers in Microbiology, 2015
Perchloroethene, Trichloroethene, and other chlorinated solvents are widespread groundwater pollutants. They form Dense Non Aqueous Phase Liquids (DNAPLs) that sink through permeable groundwater aquifers until non-permeable zone is reached.

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.

Pretreatment of Cotton Fibres with Alcohols to Optimize Dye Uptake

Caspian Journal of Environmental Sciences, 2006
Cotton fibres were subjected to cleaning process and then characterized for maturity. Decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and Trichloroethene on the native fibres were carried out.

Detoxification of 1,1,2-trichloroethane to ethene by desulfitobacterium and identification of its functional reductase gene.

PLoS ONE, 2015
1,1,2-trichloroethane (1,1,2-TCA) has become a common groundwater pollutant due to historically extensive utilization, improper disposal, as well as from incomplete dechlorination of 1,1,2,2-tetrachloroethane.

Aerobic biodegradation of chlorinated ethenes by Pseudonocardia sp. D17: Biodegradation ability without auxiliary substrates and concurrent biodegradation with 1,4-dioxane

Journal of Hazardous Materials Letters
Bioremediation is a promising approach for mitigating commingled contaminations of chlorinated ethenes (CEs) and 1,4-dioxane (DX). However, aerobic bioremediation to simultaneously remove CEs and DX remains challenging.

Combining microcosm biodegradation and reactive transport modeling to explore the feasibility of ATES-bioremediation approaches

Frontiers in Water
This study presents a process-based model analysis of non-isothermal biodegradation of chlorinated ethenes in batch microcosm setups and field-scale remediation, combining Aquifer Thermal Energy Storage with in situ bioremediation (ATES-ISB).

Enhanced In Situ Bioremediation in Source Zones

Revista Águas Subterrâneas, 2011
In situ bioremediation (ISB) can be a low-cost approach for accelerating remediation timelines at sites impacted with dense non-aqueous phase liquids (DNAPLs) such as trichloroethene (TCE) and tetrachloroethene (PCE).

CO-driven electron and carbon flux fuels synergistic microbial reductive dechlorination

Microbiome
Background Carbon monoxide (CO), hypothetically linked to prebiotic biosynthesis and possibly the origin of the life, emerges as a substantive growth substrate for numerous microorganisms.
