A Polyhydroxybutyrate (PHB)-Biochar Reactor for the Adsorption and Biodegradation of Trichloroethylene: Design and Startup Phase

Bioengineering, 2022
In this work, polyhydroxy butyrate (PHB) and biochar from pine wood (PWB) are used in a mini-pilot scale biological reactor (11.3 L of geometric volume) for trichloroethylene (TCE) removal (80 mgTCE/day and 6 L/day of flow rate).

From Energy Deprivation Stress to Catalytic Adaptation of Reductive Dehalogenase TmrA for 1,1‐DCA Dechlorination: An Experimental and in Silico Study

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Adaptive evolution of Dehalobacter restrictus strain UNSWDHB under a ratio of 1:9 chloroform:1,1‐DCA regime increased 1,1‐DCA dechlorination. Sequencing and molecular dynamics simulation reveal high‐entropy tmrA mutations that improved 1,1‐DCA binding energy and stabilize the catalytic pocket, outlining a route to tune reductive dehalogenases for ...

Coupling of bioelectrochemical toluene oxidation and trichloroethene reductive dechlorination for single-stage treatment of groundwater containing multiple contaminants

Environmental Science and Ecotechnology, 2022
Bioremediation of groundwater contaminated by a mixture of aromatic hydrocarbons and chlorinated solvents is typically challenged because these contaminants are degraded via distinctive oxidative and reductive pathways, thus requiring different ...

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)

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 ...

Elastic Deformation of Cellulose/Lignin‐Based Anode for Rejuvenating Aged Mix‐Cultured Electroactive Biofilms

Advanced Science, Volume 12, Issue 23, June 20, 2025.
A new strategy for revitalizing aged biofilms using the elastic deformation of biomass‐based flexible carbon aerogel is proposed. The elastic deformation removes the nonelectrogenic bacteria and the dead electrogenic bacteria, as well as a lot of loosely bound extracellular polymer materials.

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 ...

Thermochemical Recycling and Degradation Strategies of Halogenated Polymers (F−, Cl−, Br−): A Holistic Review Coupled with Mechanistic Insights

The Chemical Record, Volume 25, Issue 6, June 2025.
This review aims to comprehensively address recent degradation techniques (physical, chemical and biological) of halogenated waste polymers with a prime focus on thermal degradation techniques. Exploiting various metal oxides during co‐pyrolysis is deemed a viable solution for recycling halogenated polymeric waste.

Organohalide Respiring Bacteria and Reductive Dehalogenases: Key Tools in Organohalide Bioremediation

Frontiers in Microbiology, 2016
Organohalides are recalcitrant pollutants that have been responsible for substantial contamination of soils and groundwater. Organohalide-respiring bacteria (ORB) provide a potential solution to remediate contaminated sites, through their ability to use ...

Phylogenomic analysis of proteins that are distinctive of and its main subgroups and the origin of methanogenesis [PDF]

, 2007
Background The Archaea are highly diverse in terms of their physiology, metabolism and ecology. Presently, very few molecular characteristics are known that are uniquely shared by either all archaea or the different main groups within archaea.
