TL;DR: Uncultured members of the Chloroflexi phylum are highly enriched in numerous subseafloor environments and the presence of genes encoding putative reductive dehalogenases throughout the phylum expanded the phylogenetic boundary for potential organohalide respiration past the Dehalococcoidia class.

TL;DR: The structure of Dehalococcoides populations in a continuously fed reactor system under changing chloroethene/ethane influent conditions was investigated and it was observed that increasing the influent ratio of 1,2-dichloroethane to trichloraethene was associated with ecological selection of a tceA-containing Dehalitis mccartyi population relative to a vcrA- containing De Halococcoide population.

TL;DR: Although comparative physiology among these three genera reveals considerable metabolic and eco-physiological diversity consistent with their unique phylogeny, these microorganisms share similar genomic signatures, suggestive of convergent adaptive niche specialization to catabolism of naturally occurring organohalide compounds.

TL;DR: A systematic approach to tune protein levels in Methanosarcina acetivorans C2A, a model methanogen, by regulating transcription and translation initiation resulted in a predicable change in protein levels over a 60 fold range.
