Journal ArticleDOI
Dehalococcoides mccartyi gen. nov., sp. nov., obligately organohalide-respiring anaerobic bacteria relevant to halogen cycling and bioremediation, belong to a novel bacterial class, Dehalococcoidia classis nov., order Dehalococcoidales ord. nov. and family Dehalococcoidaceae fam. nov., within the phylum Chloroflexi.

TL;DR: Six obligately anaerobic bacterial isolates with strictly organohalide-respiring metabolisms obtained from chlorinated solvent-contaminated aquifers, contaminated and uncontaminated river sediments or anoxic digester sludge represent a new genus and species, for which the name Dehalococcoides mccartyi gen. nov.
Journal ArticleDOI
Dehalogenimonas lykanthroporepellens gen. nov., sp. nov., a reductively dehalogenating bacterium isolated from chlorinated solvent-contaminated groundwater
TL;DR: Morphological, physiological and chemotaxonomic traits as well as phylogenetic analysis support the conclusion that these two strains represent a novel species of a new genus in the phylum Chloroflexi, for which the name Dehalogenimonas lykanthroporepellens gen. nov., sp.
Journal ArticleDOI
Guided cobalamin biosynthesis supports Dehalococcoides mccartyi reductive dechlorination activity
TL;DR: Co-culture experiments indicated that a cobalamin is a preferred corrinoid cofactor of strains BAV1, GT and FL2 when grown with chlorinated ethenes as electron acceptors, and even though the methanogen and acetogen populations tested did not produce cobalamina, the addition of DMB enabled guided biosynthesis and generated a cobinamin that supported Dehalococcoides' activity and growth.
Journal ArticleDOI
Unexpected specificity of interspecies cobamide transfer from Geobacter spp. to organohalide-respiring Dehalococcoides mccartyi strains.

TL;DR: The findings have implications for in situ bioremediation and suggest that the corrinoid metabolism of Dehalococcoides must be understood to faithfully predict, and possibly enhance, reductive dechlorination activities.
Journal ArticleDOI
Isolation of novel bacteria within the Chloroflexi capable of reductive dechlorination of 1,2,3‐trichloropropane
TL;DR: Phylogenetic analysis based on 16S rRNA gene sequence data showed these isolates to represent a new lineage within the Chloroflexi, the first isolates reported to reductively dehalogenate 1,2,3-trichloropropane.
