Recent advances and trends of trichloroethylene biodegradation: A critical review

Frontiers in Microbiology, 2022
Trichloroethylene (TCE) is a ubiquitous chlorinated aliphatic hydrocarbon (CAH) in the environment, which is a Group 1 carcinogen with negative impacts on human health and ecosystems.

Reductive dechlorination under acidic condition [PDF]

, 2019
Chlorophenols with their toxicity, persistence and detrimental effects on the environment raise great concerns. Biological treatment seems to be the most economical way when dealing with wastewater containing these chlorinated compounds. Anaerobic dechlorination of chlorophenols has been extensively investigated. Despite it being effective in degrading

Reductive Dechlorination of the Nitrogen Heterocyclic Herbicide Picloram [PDF]

Applied and Environmental Microbiology, 1993
The anaerobic biodegradation of picloram (3,5,6-trichloro-4-amino-2-pyridinecarboxylic acid) in freshwater sediment was favored under methanogenic conditions but not when sulfate or nitrate was available as a terminal electron acceptor. Under the former conditions, more than 85% of the parent substrate (340 μM) was removed from nonsterile ...

CFD modeling and sensitivity‐guided design of silicon filament CVD reactors

AIChE Journal, EarlyView.
Abstract Filament‐based chemical vapor deposition (CVD) for silicon (Si) coatings is often treated as an adaptation of planar deposition. But this overlooks fundamental shifts in transport phenomena and reaction kinetics. In filament CVD, the filament acts as a substrate, heat source, and flow disruptor simultaneously. In this work, we ask: What really

Evaluation of the biological treatment of a real contaminated groundwater through reductive dechlorination biostimulation

Frontiers in Chemical Engineering
Chlorinated aliphatic hydrocarbons (CAHs) are common groundwater contaminants due to improper utilization in past industrial activity. Anaerobic reductive dechlorination, where bacteria use CAHs as electron acceptors, is crucial for bioremediation ...

Coexistence of two distinct Sulfurospirillum populations respiring tetrachloroethene - genomic and kinetic considerations [PDF]

, 2018
Two anaerobic bacterial consortia, each harboring a distinct Sulfurospirillum population, were derived from a 10 year old consortium, SL2, previously characterized for the stepwise dechlorination of tetrachloroethene (PCE) to cis-dichloroethene (cis-DCE)

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Diversity of dehalorespiring bacteria and selective enrichment of aryl halides-dechlorinating consortium from sedimentary environment near an oil refinery

Journal of Taibah University for Science, 2018
This study demonstrated the potential for reductive dechlorination of aryl halides in a sedimentary environment by naturally occurring bacteria. A laboratory sediment microcosm and highly enriched, stable dechlorinating cultures were established using ...

Biomass-supported catalysts on Desulfovibrio desulfuricans and Rhodobacter sphaeroides [PDF]

, 2008
A Rhodobacter sphaeroides-supported dried, ground palladium catalyst (‘‘Rs-Pd(0)’’) was compared with a Desulfovibrio desulfuricans-supported catalyst (‘‘Dd-Pd(0)’’)and with unsupported palladium metal particles made by reduction under H2 (‘‘Chem-Pd(0)’’)
