A common and previously unknown ecological niche: the halorespiration of natural organochlorines in terrestrial soil and sediment
The phylum <italic>Chloroflexi</italic> contains several isolated bacteria that have been found to dechlorinate a diverse array of halogenated anthropogenic chemicals. These bacteria use organohalogens, such as polychlorinated biphenyls and trichloroethene, as their terminal electron acceptors and …

The evolution and diversity of noncanonical microbial nitrogen metabolisms
… (nirS) structure within members of Phylum Chloroflexi, which includes a cytochrome superfamily domain in addition to functional domains conserved in Proteobacterial nirS. Phylogenetic domain mapping reveals that this gene resulted from a chimeric domain fusion in ancestral Chloroflexi. I …

Hitching a ride: A gastropod-associated microbiome community at a Hydrate Ride methane seep and impacts on local biogeochemical cycling
… nelsonii, and a previously undescribed Chloroflexi. Our analysis of three incomplete Chloroflexi’s genomes leads us to hypothesize that the Chloroflexi is an acetogen. Environmental samples from a previous sample revealed that the gastropod-associated community differed from the …

Molecular characterization of microbial communities in small-scale biodigesters using whole genome shotgun metagenomic approach
… bacterial phyla, followed by Actinobacteria and Chloroflexi in cow dung-fed biodigesters. The archaeal community was dominated by Euryarchaeota, with Methanomicrobiales and Methanobacteriales as the predominant orders. Functional analysis reveals that most identified microorganisms contribute …

Microbial transformation of arsenic in Bengal floodplain
… Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi and Firmicutes but the overall diversity of bacteria was shown to be significantly higher in Holocene compared to Pleistocene soil. Metagenomics indicated that Geobacter, an anaerobic arsenic resistant organism, was most abundant in …

Influence of plant species, location, and seasonality on rhizosphere bacterial communities in freshwater wetlands
… A. virginicus, while Planctomycete (OTU06) and Chloroflexi (OTU08) phyla are associated with C. lurida. However, the top 10 OTUs are not associated with J. effusus. Rhizosphere bacterial communities of A. virginicus were significantly different from those of C. lurida and J. effusus across all …

Redutive Dehalogenation of Chlorinated Alkanes by Novel Bacteria at the PetroProcessor of Louisiana Inc. Superfund Site
… isolates to represent a new lineage within the Chloroflexi. Their closest previously cultured relatives are “Dehalococcoides” strains with 16S rRNA gene sequence similarities of only 90%. A quantitative real-time PCR (qPCR) approach targeting 16S rRNA genes indicated that both strains couple …

Assessing the microbial community structure’s diversity associated with nutrients concentration in the natural wetland systems
… observed in Lake Icubhu, members of Firmicutes, Chloroflexi and Bacteroidetes were also dominant at Nhlabane Estuary. Finally, some representatives of Thermomicrobia, Fusobacteria, Verrucomicrobia and Fusobacteria were also retrieved from some samples. Based on the results of nutrients, microbial …

The physiological characterisation of a novel Thermomicrobia strain WKT50.2, and a review of the characteristics of the class Thermomicrobia
… obligate aerobes within the phylum Chloroflexi. At the time of writing, it contained four distinct species, Thermomicrobium roseum, Sphaerobacter thermophilus, Nitrolancetus hollandicus and WKT50.2, the novel strain described in this study. The physiology and ecology of this strain, …

Biological degradation of soluble microbial products in a combined system of anaerobic packed-bed reactors and a down-flow hanging sponge reactor
… with the abundance of Bacteroidetes and Chloroflexi among the dominant populations. These populations may take charge of initiating the degradation of organic compounds in the system. Next, the biological degradation of SMP, with respect to the selective enrichment of the microbial …

Distribution of Dehalococcoidia in marine sediments and strategies for their enrichment
… bacteria of the class Dehalococcoidia, phylum Chloroflexi, are one of the most widespread and abundant bacteria inhabiting the marine subsurface. However, their physiology and ecological role are unknown. In this study, marine sediments were cultivated with various potential electron acceptors …

Impact of Oxygen and Pesticides on Microbial Cellulose Degradation in Aerated Agricultural Soils: A Microscaled Analysis of Processes and Prokaryotic Populations
… taxa 'Sphingo1-4' (Bacteroidetes) and 'Deha1' (Chloroflexi), and Planctomycetaceae (Planctomycetes) were involved. Active community members in [13C]-cellobiose and [13C]-glucose treatments differed from those in [13C]-cellulose treatments, and were selectively activated by O2. Twenty-eight of …

Bacterial communities in glacier forefields of the Larsemann Hills, East Antarctica : structure, development & adaptation
… Proteobacteria, Bacteroidetes, Cyanobacteria and Chloroflexi. The connection of soil characteristics with bacterial community structure showed that soil parameter and soil formation along the glacier forefield influence the distribution of certain phyla. In the early step of succession the …
