Chemical compound and disease context of Butyrivibrio

• The structure of a new acidic sugar from the extracellular polysaccharide of Butyrivibrio fibrisolvens strain 49 was determined as 4-O-(1-carboxyethyl)-D-galactose on the basis of 13C-n.m.r. and 1H-n.m.r. spectroscopy, m.s. and chemical degradation studies [11].
• Intermolecular transacylation of phosphatidylethanolamine by a Butyrivibrio sp [12].
• Similar values were measured for the order parameter of cell membranes of Butyrivibrio S2 regardless of whether the organism was grown on myristic, palmitic, or stearic acid [13].
• A new series of long-chain dicarboxylic acids with vicinal dimethyl branching found as major components of the lipids of Butyrivibrio spp [14].
• The complex lipids of the naturally-occurring general-fatty-acid-auxotroph Butyrivibrio S2 [Hazlewood & Dawson (1979) J. Gen. Microbiol. 112, 15-27] grown with palmitic acid as sole fatty-acid supplement have been investigated and some have been isolated in a state of purity and analysed [15].

Biological context of Butyrivibrio

• The cloning, expression and nucleotide sequence of a 3 kb DNA segment on pLS206 containing a xylanase gene (xynB) from Butyrivibrio fibrisolvens H17c was investigated [16].

• Isolation of a novel strain of Butyrivibrio fibrisolvens that isomerizes linoleic acid to conjugated linoleic acid without hydrogenation, and its utilization as a probiotic for animals [18].
• The structure of Butyrivibrio fibrisolvens strain 49 capsular polysaccharide has been investigated mainly by sugar and methylation analysis, partial chemical degradations, NMR spectroscopy, and mass spectrometry [19].
