'''Butyrivibrio fibrisolvens D1T'''

Butyrivibrio fibrisolvens D1T (DSM 3071) was originally isolated from bovine rumen contents in the USA [1] and subsequently described and named by Bryant and Small [2]. It has a Gram-positive cell wall but stains Gram-negative [3]. It is the type species of the genus Butyrivibrio within the family Lachnospiraceae and the type stain of the B. fibrisolvens species [4]

D1 is an anaerobic bacterium that ferments a broad range of complex plant polysaccharides including xylan, pectin, and starch, and produces primarily butyrate, formate, lactate, H₂, and CO₂. D1 has a large repertoire of carbohydrate active enzymes (126 glycosyl hydrolases, 113 glycosyl transferases, 2 polysaccharide lyases, 14 carbohydrate esterases) [5]

The D1 genome (4,934,347 bp) consists of a chromosome (4,671,138 bp) and two plasmids (242,710 bp and 20,499 bp) [6].

Rumen butyrivibrios are among the few bacteria shown to possess two distinct respiratory enzyme complexes, Rnf and Ech, which couple with two ATP synthases in separate chemiosmotic circuits and impact energy conservation in these organisms [7]. In D1 the genes for the Ech hydrogenase (echABCDEF) and the associated hydrogenase maturation proteins are clustered adjacent to the replication origin of the 243 kb plasmid. This plasmid also encodes a large cell-wall associated pectin methylesterase [8] predicted to produce methanol, a substrate for methylotrophic methanogens, from methoxylated substrates such as pectin.
