The Deltaproteobacteria are a class of Proteobacteria.[1] All species of this group are, like all Proteobacteria, Gram-negative.
The Deltaproteobacteria comprise a branch of predominantly aerobic genera, the fruiting body-forming Myxobacteria which release myxospores in unfavorable environments, and a branch of strictly anaerobic genera, which contains most of the known sulfate- (Desulfovibrio, Desulfobacter, Desulfococcus, Desulfonema, etc.) and sulfur-reducing bacteria (e.g. Desulfuromonas spp.) alongside several other anaerobic bacteria with different physiology (e.g. ferric iron-reducing Geobacter spp. and syntrophic Pelobacter and Syntrophus spp.).
A pathogenic intracellular deltaproteobacterium has recently been identified.[2]
It has been proposed that the Deltaproteobacteria be split into four new phyla: Desulfobacterota, Myxococcota, Bdellovibrionota, and SAR324 (a placeholder name pending the description of type material).[3]
Phylogeny
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [4] and National Center for Biotechnology Information (NCBI)[5] and the phylogeny is based on 16S rRNA-based LTP release 111 by 'The All-Species Living Tree' Project[6]
