Microbially-mediated halogenation and dehalogenation cycling of organohalides in the ocean [PDF]
Nature CommunicationsMicrobially mediated organohalide cycling in the ocean has profound implications for global biogeochemical cycles and climate, but the geographic distribution and diversity of the halogenation-dehalogenation cycling microorganisms remain unknown.

Evidence of microbial reductive dehalogenation in deep-sea cold seeps and its implications for biogeochemical cycles [PDF]
MicrobiomeBackground Reductive dehalogenation is crucial for halogen cycling and environmental remediation, yet its ecological role is not completely understood, especially in deep-sea environments. To address this gap, we investigated the diversity and expression

From Energy Deprivation Stress to Catalytic Adaptation of Reductive Dehalogenase TmrA for 1,1-DCA Dechlorination: An Experimental and in Silico Study. [PDF]
Microb BiotechnolAdaptive 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 ...
