Reductive dehalogenase of Dehalococcoides mccartyi strain CBDB1 reduces cobalt- containing metal complexes enabling anodic respiration by Marie Eberwein, Nadine Hellmold, Ronny Frank, Darja Deobald, Lorenz Adrian, Lorenz Adrian

“…Through various biochemical approaches, we show that cobalt chelates are specifically reduced by CBDB1 cells, putatively by the reductive dehalogenase subunit (RdhA) of the OHR complex. …”

Evidence of microbial reductive dehalogenation in deep-sea cold seeps and its implications for biogeochemical cycles by Yingchun Han, Zhaochao Deng, Yongyi Peng, Jiaxue Peng, Lei Cao, Yangru Xu, Yi Yang, Hao Zhou, Chen Zhang, Dongdong Zhang, Minxiao Wang, Chunfang Zhang, Chris Greening, Xiyang Dong

“…To address this gap, we investigated the diversity and expression of genes encoding reductive dehalogenase catalytic subunits (RdhAs), and ecophysiology of potential organohalide reducers in deep-sea cold seeps, which are environments rich in halogenated compounds. …”

Whole metagenome sequencing and 16S rRNA gene amplicon analyses reveal the complex microbiome responsible for the success of enhanced in-situ reductive dechlorination (ERD) of a te... by Rebecca A Reiss, Peter A Guerra, Oleg Makhnin, Matthew Kellom

“…The presence of tetrachloroethene biodegradation byproducts, organohalide respiring genera (OHRG), and reductive dehalogenase (rdh) genes detected in groundwater samples indicated that enhanced reductive dechlorination (ERD) was the remedy of choice. …”

Genome-resolved transcriptomics reveals novel PCE-dehalogenating bacteria from Aarhus Bay sediments by Chen Zhang, Tom N. P. Bosma, Siavash Atashgahi, Hauke Smidt

“…Sixteen bins harbored RDase genes and were affiliated taxonomically to the class of Bacilli and phyla of Bacteroidota, Synergistota, and Spirochaetota, which have not been reported to catalyze reductive dehalogenation. Among the 16 bins, bin.26, phylogenetically close to the genus Vulcanibacillus (phylum Firmicutes), contained an unprecedented 97 reductive dehalogenase (RDase) genes. …”
