Register list for 4 new names including Caproiciproducens ruminis sp. nov.

Submitted by Loy, Alexander

Genus Neosphaerochaeta

Etymology: [Ne.o.sphae.ro.chae'ta] Gr. masc. adj. neos, new; N.L. fem. n. Sphaerochaeta, a bacterial genus; N.L. fem. n. Neosphaerochaeta, a new genus related to Sphaerochaeta
Nomenclatural type: Species Neosphaerochaeta fermentans^Ts
Description: The nomenclatural type of this genus was derived from anoxic incubations of cow rumen fluid with sulfoquinovose.
Classification: Bacteria » Spirochaetota » Spirochaetia » Spirochaetales » Sphaerochaetaceae » Neosphaerochaeta
References: Effective publication: Krasenbrink et al., 2026 [1]
Registry URL: https://seqco.de/i:54964

Species Caproiciproducens intestini

Etymology: [in.tes.ti'ni] L. gen. neut. n. intestini, of the gut, referring to the origin of the bacterium
Nomenclatural type: NCBI Assembly: GCA_053840945.1 ^Ts
Description: The designated DNA sequence is MAG SQrumen2 recovered from cow rumen. This species was enriched in anoxic incubations of rumen fluid with sulfoquinovose. Genome-centric metatranscriptomic analysis suggests that sulfoquinovose is fermented via a bifurcated sulfo-transketolase/transaldolase pathway to isethionate and an unidentified sulfonate product.
Classification: Bacteria » Bacillota » Clostridia » Eubacteriales » Ocillospiraceae » Caproiciproducens » Caproiciproducens intestini
References: Effective publication: Krasenbrink et al., 2026 [1]

Species Caproiciproducens ruminis

Etymology: [ru.mi'nis] L. gen. neut. n. ruminis, of the rumen, the source of the bacterium
Nomenclatural type: NCBI Assembly: GCF_053840905.1 ^Ts
Description: The designated DNA sequence is MAG SQrumen1 recovered from cow rumen. This species was enriched in anoxic incubations of rumen fluid with sulfoquinovose. Genome-centric metatranscriptomic analysis suggests that sulfoquinovose is fermented via a bifurcated sulfo-transketolase/transaldolase pathway to isethionate and an unidentified sulfonate product.
Classification: Bacteria » Bacillota » Clostridia » Eubacteriales » Ocillospiraceae » Caproiciproducens » Caproiciproducens ruminis

Species Neosphaerochaeta fermentans^Ts

Etymology: [fer.men'tans] L. fem. part. adj. fermentans, fermenting, referring to the source of genome from a sulfoquinovose fermenting bacterium
Nomenclatural type: NCBI Assembly: GCA_053840885.1 ^Ts
Description: The designated DNA sequence is MAG SQrumen3 recovered from cow rumen. This species was enriched in anoxic incubations of rumen fluid with sulfoquinovose. Genome-centric metatranscriptomic analysis suggests sulfoquinovose is fermented to isethionate via the sulfo-transketolase pathway. The genome additionally encodes two different sulfoquinovosidases (YihQ and SqgA).
Classification: Bacteria » Spirochaetota » Spirochaetia » Spirochaetales » Sphaerochaetaceae » Neosphaerochaeta » Neosphaerochaeta fermentans^Ts
