Fibrobacter
Genus of cellulose-degrading bacteria
From Wikipedia, the free encyclopedia
Fibrobacter is a genus of Gram-negative, rod-shaped and obligately anaerobic bacteria in the family Fibrobacteraceae of the phylum Fibrobacterota. Members of the genus degrade cellulose and other plant cell-wall polysaccharides and occur in the gastrointestinal tracts of herbivorous mammals.[2]

The genus contains two species with validly published names: Fibrobacter intestinalis and Fibrobacter succinogenes.[1] F. succinogenes, the type species, is commonly associated with the rumen, whereas strains of F. intestinalis have been isolated from the lower intestinal tracts of non-ruminant animals.[3] Genome comparisons have identified substantial diversity among cultured strains and differences in the numbers of genes encoding carbohydrate-active enzymes between lineages associated with the rumen and hindgut.[4]
Taxonomy
The genus was established in 1988 after comparison of 16S rRNA sequences showed that the species then known as Bacteroides succinogenes was not closely related to the type species of Bacteroides. It was transferred to Fibrobacter as F. succinogenes, and F. intestinalis was described at the same time.[3]
The name Fibrobacter combines the Latin word fibra, meaning "fibre" or "filament", with the Neo-Latin word bacter, meaning "rod", referring to a rod-shaped bacterium that subsists on fibre.[1]
