Proposal to reclassify the proteobacterial classes Deltaproteobacteria and Oligoflexia, and the phylum Thermodesulfobacteria into four phyla reflecting major functional capabilities

International Journal of Systematic and Evolutionary Microbiology, 2020
The classDeltaproteobacteriacomprises an ecologically and metabolically diverse group of bacteria best known for dissimilatory sulphate reduction and predatory behaviour. Although this lineage is the fourth described class of the phylumProteobacteria, it rarely affiliates with other proteobacterial classes and is frequently not recovered as a ...

Characterization of the Deltaproteobacteria in contaminated and uncontaminated stream sediments and identification of potential mercury methylators [PDF]

Aquatic Microbial Ecology, 2012
Microbial communities were examined in surface stream sediments at 5 conta - minated sites and 1 control site near Oak Ridge, TN, USA, to identify bacteria that could be con- tributing to mercury (Hg) methylation. The phylogenetic composition of the sediment bacterial community was examined over 3 quarterly sampling periods (36 samples) using 16S rRNA ...

Position of Deltaproteobacteria Cas12e nuclease cleavage sites depends on spacer length of guide RNA [PDF]

RNA Biology, 2020
Cas12e proteins (formerly CasX) form a distinct subtype of Class II type V CRISPR-Cas effectors. Recently, it was shown that DpbCas12e from Deltaproteobacteria and PlmCas12e from Planctomycetes can introduce programmable double-stranded breaks in mammalian genomes.

Evidence for tropical endemicity in the Deltaproteobacteria Marine Group B/SAR324 bacterioplankton clade [PDF]

Aquatic Microbial Ecology, 2007
The fine-scale phylogeny of the deeply branching Deltaproteobacteria Marine Group B/SAR324 (MGB/SAR324) bacterioplankton clade was analyzed using partial 16S rRNA gene sequence and internal transcribed spacer (ITS) sequences. Both sets of analyses revealed consider- able sequence variation, which, along with bootstrap calculations, strongly support the

Desulfovibrio portus sp. nov., a novel sulfate-reducing bacterium in the class Deltaproteobacteria isolated from an estuarine sediment

Journal of General and Applied Microbiology, 2009
A strictly anaerobic, mesophilic, sulfate-reducing bacterial strain (MSL79T) isolated from an estuarine sediment in the Sea of Japan of the Japanese islands was characterized phenotypically and phylogenetically. Cells were Gram-negative, motile with a polar flagellum, non-spore-forming, curved rods.

Morphological features of elongated-anisotropic magnetosome crystals in magnetotactic bacteria of the Nitrospirae phylum and the Deltaproteobacteria class

Earth and Planetary Science Letters, 2011
High resolution transmission electron microscopy was used to study the crystallographic habits of the elongated magnetite crystals, variously described as bullet-, tooth- or arrowhead-shaped, in two recently described, uncultured, magnetotactic bacteria belonging to the Nitrospirae phylum designated Candidatus Magnetoovum mohavensis strain LO-1, and ...

Desulfoferrobacter suflitae gen. nov., sp. nov., a novel sulphate-reducing bacterium in the Deltaproteobacteria capable of autotrophic growth with hydrogen or elemental iron

International Journal of Systematic and Evolutionary Microbiology, 2022
A mesophilic sulphate-reducing micro-organism, able to grow chemolithoautotrophically with H2/CO2 (20 : 80) and with elemental iron as a sole electron donor, was isolated from a consortium capable of degrading long-chain paraffins and designated strain DRH4T. Cells were oval shaped often with bright refractile cores and occurred singly or in pairs. The
