Unveiling organohalide respiration potential in River Nile sediments via 16S rRNA gene amplicon sequencing of endogenous bacterial communities [PDF]

BMC Microbiology
Background Industrial waste, agricultural runoff and untreated sewage contaminate the Nile, leaving a toxic legacy in its sediments. Organohalides-polluted sediment in particular poses serious public health risks and detrimental effects on aquatic life ...

Organohalide-respiring bacteria in polluted urban rivers employ novel bifunctional reductive dehalogenases to dechlorinate polychlorinated biphenyls and tetrachloroethene.

Environmental Science & Technology, 2020
Polluted urban river sediments could be a sink of persistent and toxic polychlorinated biphenyls (PCBs) in urban areas and provide desired growth niches for organohalide-respiring bacteria (OHRB).

Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases [PDF]

Biodegradation, 2018
The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive ...

Roles of Organohalide-Respiring Dehalococcoidia in Carbon Cycling

mSystems, 2020
The class Dehalococcoidia within the Chloroflexi phylum comprises the obligate organohalide-respiring genera Dehalococcoides, Dehalogenimonas, and “Candidatus Dehalobium.” Knowledge of the unique ecophysiology and biochemistry of Dehalococcoidia has been

Burning question: Rethinking organohalide degradation strategy for bioremediation applications. [PDF]

Microb Biotechnol
This review specifically focuses on the novel solution of organohalide bioremediation, proposing redox‐potential‐mediated hybrid bioprocesses tailored to the complexities of organohalide pollution. Abstract Organohalides are widespread pollutants that pose significant environmental hazards due to their high degree of halogenation and elevated redox ...

Resilience and functional redundancy of methanogenic digestion microbiome safeguard recovery of methanogenesis activity under the stress induced by microplastics

mLife, Volume 2, Issue 4, Page 378-388, December 2023., 2023
Abstract Microplastics and nanoplastics are emerging pollutants that substantially influence biological element cycling in natural ecosystems. Plastics are also prevalent in sewage, and they accumulate in waste‐activated sludge (WAS). However, the impacts of plastics on the methanogenic digestion of WAS and the underpinning microbiome remain ...

Spatial and temporal dynamics of organohalide-respiring bacteria in a heterogeneous PCE-DNAPL source zone.

Journal of Contaminant Hydrology, 2015
Effective treatment of sites contaminated with dense non-aqueous phase liquids (DNAPLs) requires detailed understanding of the microbial community responses to changes in source zone strength and architecture. Changes in the spatial and temporal distributions of the organohalide-respiring Dehalococcoides mccartyi (Dhc) strains and Geobacter lovleyi ...

Dehalococcoides mccartyi strain NIT01 grows more stably in vessels made of pure titanium rather than the stainless alloy SUS304

Environmental Microbiology Reports, Volume 15, Issue 6, Page 557-567, December 2023., 2023
To establish large‐scale cultivation of Dehalococcoides, 7–10 litre culturing of Dehalococcoides mccartyi strain NIT01 was performed using three different vessels made of glass, stainless alloy SUS304, and titanium. The unbreakable titanium vessel demonstrated complete dechlorination of trichloroethene (TCE) to ethene, even after being reused five ...

Ensuring the continued success of a mulch biowall at a trichloroethylene‐contaminated superfund site: Lessons learned

Remediation Journal, Volume 33, Issue 4, Page 323-337, Fall 2023., 2023
Abstract Trichloroethylene (TCE) is a toxic organic compound, which can adversely affect human health. The chemical is one of the most frequently found contaminants in groundwater in the United States and around the world. A landfill in Maryland contaminated with high levels of TCE decades ago was added to the U.S.
