Floccifex
Genus of Gram-positive anaerobic bacteria
From Wikipedia, the free encyclopedia
Floccifex is a genus of Gram-positive, strictly anaerobic bacteria belonging to the family Erysipelotrichaceae. It was first described in 2021 based on the isolation of its type species, Floccifex porci, from the feces of a pig in Germany.[1]

Taxonomy
The genus Floccifex was proposed as part of a large-scale culturomics and phylogenomic study of the pig gut microbiota. Phylogenetic analysis based on 16S rRNA gene sequences and genome comparisons placed it in the family Erysipelotrichaceae, distinct from other closely related genera.[1]
Characteristics
Floccifex species are coccoid to rod-shaped, Gram-positive, and non-spore-forming. They grow under strictly anaerobic conditions and form flocculent aggregates in liquid culture, an attribute referenced in the genus name ("floccus" = flock, "fex" = maker).
