Journal ArticleDOI
Effect of 3-phenylpropanoic Acid on growth of and cellulose utilization by cellulolytic ruminal bacteria.
Robert J. Stack,Michael A. Cotta +1 more
TL;DR: Comparative rates of growth obtained for Ruminococcus flavefaciens FD1 or C94 and Butyrivibrio fibrisolvens 12, 49, or A38 were similar regardless of the PPA content of the growth medium, while with Ruminoccoccus albus 7 and 8, the addition of PPA greatly enhanced the rate of cellulose utilization.
Journal ArticleDOI
Neutral sugar composition of extracellular polysaccharides produced by strains of Butyrivibrio fibrisolvens.
TL;DR: The extracellular polysaccharides produced by 37 isolates presently classified as Butyrivibrio species were purified from glucose-grown cultures and showed that while the neutral sugar composition of the EPS was constant for a given strain, it varied considerably between strains.
Journal ArticleDOI
Taxonomic Relatedness of Butyrivibrio, Lachnospira, Roseburia, and Eubacterium Species as Determined by DNA Hybridization and Extracellular-Polysaccharide Analysis
TL;DR: The data suggest that for some groups of microorganisms EPS analysis may be a useful adjunct to DNA analysis to clarify complex taxonomic relationships.
Journal ArticleDOI
Identification of L-altrose in the extracellular polysaccharide from Butyrivibrio fibrisolvens strain CF3
TL;DR: Butyrivibrio fibrisolvens strain CF3, a stricyly anaerobic bacterial isolate from the ovine cecum, produces extracellular polysaccharides (EPS) when grown on a defined medium containing glucose as the carbon source.
