Hominenteromicrobium is a monotypic genus of obligately anaerobic bacteria within the family Oscillospiraceae. It was first described in 2022 following the isolation of its type and only species, Hominenteromicrobium mulieris, from the feces of a healthy adult woman using anaerobic single-cell sorting techniques.[1]
Taxonomy
[edit]The name Hominenteromicrobium is derived from Latin: homo (human), enteron (gut), and microbium (microbe), reflecting its origin in the human gastrointestinal tract.[1] The genus was validly published in 2023 and is listed in the List of Prokaryotic names with Standing in Nomenclature (LPSN).[2]
Species
[edit]The genus currently contains a single known species, Hominenteromicrobium mulieris. The species epithet mulieris means "of a woman" in Latin, referencing the human donor from whom the bacterium was first isolated. The type strain, CLA-AA-H250, is deposited in public culture collections as DSM 113252 and JCM 35907.[3]
Morphology and physiology
[edit]Hominenteromicrobium mulieris cells are spindle-shaped coccobacilli approximately 1.5 µm in length, and they frequently form pairs under anaerobic growth conditions. The bacterium is strictly anaerobic and can utilize starch, cellulose, sulfide, and L-serine. Genome-based metabolic predictions indicate production of propionate, L-cysteine, and L-glutamate.[1]
Genomics
[edit]Complete genome sequences of two strains of H. mulieris, CIP 112194 and CIP 112527, have been published. Each strain contains a single circular chromosome with a genome size of approximately 3.1 Mb and a G+C content of 52.4%. These genomes encode over 3,000 protein-coding genes. [4]
