Hornefia butyriciproducens Hornefia porci

Hornefia is a genus of Gram-positive, strictly anaerobic, non-spore-forming bacteria belonging to the family Anaerovoracaceae. It was first described in 2020 following the isolation of two species, Hornefia butyriciproducens and Hornefia porci , from the porcine gastrointestinal tract. ^[1]

Etymology

The genus name Hornefia honors Professor Mathias W. Hornef, a German microbiologist recognized for his contributions to research on neonatal enteric infections. ^[2]

Species

The genus contains the following validly published species:

• Hornefia butyriciproducens – the type species, characterized by butyrate production during fermentation.
• Hornefia porci – similarly isolated from the swine gut, with distinct metabolic features. ^[1]
