Genomic insights into diverse bacterial taxa that degrade extracellular DNA in marine sediments

Abstract
AbstractExtracellular DNA is a major macromolecule in global element cycles, and is a particularly crucial phosphorus, nitrogen and carbon source for microorganisms in the seafloor. Nevertheless, the identities, ecophysiology and genetic features of DNA-foraging microorganisms in marine sediments are largely unknown. Here, we combined microcosm experiments, DNA stable isotope probing (SIP), single-cell SIP using nano-scale secondary isotope mass spectrometry (NanoSIMS) and genome-centric metagen

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

Waite et al. (2020). International Journal of Systematic and Evolutionary Microbiology 70 (11)
Names
Myxococcia Polyangiia Pseudobdellovibrionaceae Bdellovibrionota Oligoflexia “Desulfofervidales” Ca. Desulfofervidaceae Ca. Desulfofervidus “Desulfofervidia” Ca. Magnetomorum “Magnetomoraceae” “Adiutricaceae” Ca. Adiutrix Myxococcota “Adiutricales”
Abstract
The class Deltaproteobacteria comprises 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 phylum Proteobacteria , it rarely affiliates with other proteobacterial classes and is freque

Long-Term Transcriptional Activity at Zero Growth of a Cosmopolitan Rare Biosphere Member

Citation

Names
Desulfosporosinus infrequens
Abstract
The microbial rare biosphere represents the largest pool of biodiversity on Earth and constitutes, in sum of all its members, a considerable part of a habitat’s biomass. Dormancy or starvation is typically used to explain the persistence of low-abundance microorganisms in the environment. We show that a low-abundance microorganism can be highly transcriptionally active while remaining in a zero-growth state for at least 7 weeks. Our results provide evidence that this zero growth at a high cellul
