Register list for 3 new names including Acidulidesulfobacteriota phyl. nov.

Submitted by Ren, Yanhu

Abstract

Acidulidesulfobacterales was a formerly proposed bacterial order within the Deltaproteobacteria lineage (Tan et al., 2019). Our phylogenomic, 16S rRNA gene, and AAI analyses indicated that this lineage represents a distinct phylum-level clade, leading us to propose the designation Acidulidesulfobacteriota. It currently comprises a single class, Aciduloidesulfobacteriia, and six distinct orders. Four of these are designated as Acididesulfobacterales, Acidulidesulfobacterales (originally proposed by Tan et al. 2019), Hydrothermoacidobacterales, and Acidulidesulfobacteriales

Phylum Acidulidesulfobacteriota

Etymology
[A.ci.du.li.de.sul.fo.bac.te.ri.o'ta] N.L. neut. n. Acidulidesulfobacterium, referring to the type genus Acidulidesulfobacterium; -ota, ending to denote a phylum; N.L. neut. pl. n. Acidulidesulfobacteriota, the Acidulidesulfobacterium phylum
Nomenclatural type
Genus Acidulidesulfobacterium
Description
Acidulidesulfobacteriota represents an ecologically significant group in sulfur-rich environments including artificial acid mine drainage and hydrothermal sulfides. Phylogenomic and 16S rRNA gene analyses indicated that this lineage represents a distinct phylum-level clade, leading us to propose the designation Acidulidesulfobacteriota. Notably, the concatenated DsrAB protein phylogeny and the mixed enzyme types involved in Dsr-dependent dissimilatory sulfur metabolism suggest that Acidulidesulfobacteriota may represent a transitional lineage in the evolutionary shift from reductive to oxidative Dsr metabolism.
