Biology:Ellagibacter

From HandWiki

Ellagibacter is a genus of Gram-positive and strictly anaerobic bacteria in the family Eggerthellaceae, within the phylum Actinomycetota. The type and only species, Ellagibacter isourolithinifaciens, was isolated from a fecal sample of a healthy human.[1]

Etymology

The genus name Ellagibacter is derived from modern Latin: acidum ellagicum (ellagic acid) and bacter (rod), meaning "ellagic acid-transforming rod."

Characteristics

Members of this genus are obligate anaerobes that play a role in polyphenol metabolism in the human gut microbiome. E. isourolithinifaciens is known to convert ellagic acid into isourolithin A, a urolithin metabolite with potential health benefits including anti-inflammatory and antioxidant effects.[1][2]

Species

As of 2025, the genus Ellagibacter includes only one validly published species:

  • Ellagibacter isourolithinifaciens
