Izemoplasma acidinucleici sp. nov.

Submitted by Loy, Alexander

Order Izemoplasmatales

Etymology: [I.ze.mo.plas.ma.ta'les] N.L. neut. n. Izemoplasma, the type genus of the order; L. fem. pl. suff. -ales, ending to denote an order; N.L. fem. pl. n. Izemoplasmatales, the Izemoplasma order
Nomenclatural type: Genus Izemoplasma
Description: The type species of this order is Izemoplasma acidinucleici capable of degrading and metabolizing nucleic acids. Comparative genomics indicated that diverse Izemoplasmatales members encode multiple (up to five) predicted extracellular nucleases and are probably specialized DNA-degraders.
Classification: Bacteria » Bacillota » Bacilli » Izemoplasmatales

Family Izemoplasmataceae

Etymology: [I.ze.mo.plas.ma.ta'ce.ae] N.L. neut. n. Izemoplasma, the type genus of the family; L. fem. pl. suff. -aceae, ending to denote a family; N.L. fem. pl. n. Izemoplasmataceae, the Izemoplasma family
Nomenclatural type: Genus Izemoplasma
Description: The type species of this family is Izemoplasma acidinucleici capable of degrading and metabolizing nucleic acids. Comparative genomics indicated that diverse Izemoplasmataceae encode multiple (up to five) predicted extracellular nucleases and are probably specialized DNA-degraders.
Classification: Bacteria » Bacillota » Bacilli » Izemoplasmatales » Izemoplasmataceae

Genus Izemoplasma

Etymology: [I.ze.mo.plas'ma] Gr. neut. n. izema, a settling down, sediment; Gr. neut. n. plasma, anything formed or moulded, image, figure; N.L. neut. n. Izemoplasma, a form from sediment
Nomenclatural type: Species Izemoplasma acidinucleici^Ts
Description: We have revised the previously suggested genus name Ca. Izimaplasma (Skennerton et al., 2016) to Izemoplasma of the family Izemoplasmataceae and order Izemoplasmatales. Members of this genus degrade and metabolize nucleic acids.

Species Izemoplasma acidinucleici^Ts

Etymology: [a.ci.di.nu.cle'i.ci.] N.L. neut. n. acidum nucleicum, nucleic acid; N.L. gen. n. acidinucleici, of nucleic acid, referring to the capacity of this species to degrade and metabolize nucleic acids
Nomenclatural type: NCBI Assembly: GCA_004195325.1 ^Ts
Description: Based on a combination of unique phylogeny (based on 16S rRNA genes and concatenated single copy marker proteins) and genomic similarity (ANI), as well as genome-based predictions of nucleic acid catabolism that are supported by SIP results, we propose a novel species name Izemoplasma acidinucleici for the Izemoplasma MAG recovered in this study. We have revised the previously suggested genus name Ca. Izimaplasma to Izemoplasma of the family Izemoplasmataceae and order Izemoplasmatales.
