Phylum Ryujiniota

Etymology
[Ry.u.ji.ni.o'ta] N.L. fem. n. Ryujinia, referring to the type genus Ryujinia; -ota, ending to denote a phylum; N.L. neut. pl. n. Ryujiniota, the Ryujinia phylum
Nomenclatural type
Genus Ryujinia
Description
Ryujiniota phyl. nov. has a global distribution and was mainly present in public shotgun metagenome datasets labelled as marine sediment metagenome, peat metagenome, sediment metagenome, soil metagenome and groundwater metagenome. The highest relative abundances of Ryujiniota were found in Costa Rica margin subsurface and east pacific subsurface metagenomes with 15.75% and 15.33%, respectively.

Species Ryujinia shimokitaTs

Etymology
[shi.mo.ki'ta] N.L. fem. n. shimokita, named after the sampling site, the international waters off the Shimokita Peninsula in Japan
Nomenclatural type
INSDC Nucleotide: BAAGKY000000000.1 Ts
Description
This uncultured species is represented by the genome ‘SP_28H5_5’, whose genome size is 2.0 MB, with the presence of 23S, 16S and 5S rRNA genes. R. shimokita is inferred to have a chemolithotrophic lifestyle, since this species encodes a nearly complete Wood–Ljungdahl (WL) pathway. It also has the potential for a heterotrophic lifestyle with substrate-level phosphorylation through glycolysis, while it lacks most genes for the citrate cycle and beta-oxidation. The type genome does not encode the ability for the oxidoreduction of nitrogen or sulphur compounds.
