Prevotella ruminicola 23T
Introduction
Prevotella ruminicola 23 (ATCC 19189, DSM 19721), also known as Xylanibacter ruminicola 23, is an obligately anaerobic, Gram-negative bacterium originally isolated from the bovine rumen [1]. It is the type strain of P. ruminicola and was originally described as Bacteroides ruminicola by Bryant et al. in 1958 [1]. The species was subsequently transferred to the genus Prevotella in 1990 [2].
P. ruminicola 23 contributes to the degradation of plant polysaccharides in the rumen, particularly xylan and other hemicelluloses. Its genome encodes numerous carbohydrate-active enzymes involved in the degradation of non-cellulosic polysaccharides [3]. Several xylan-degrading enzymes have been characterized, including a bifunctional xylanase/endoglucanase and a GH10 xylanase–ferulic acid esterase [4, 5].
The genome sequence of P. ruminicola 23 is available under GenBank accession CP002006 [3]. The species was reclassified as Xylanibacter ruminicola following a taxonomic revision of the genus Prevotella [6]. However, LPSN currently retains Prevotella ruminicola as the correct name.
