Fermentation of xylans by Butyrivibrio fibrisolvens and other ruminal bacteria.
The ability of Butyrivibrio fibrisolvens and other ruminal bacteria (6 species, 18 strains) to ferment a crude xylan from wheat straw or to ferment xylans from larchwood or oat spelts was studied. Liquid cultures were monitored for carbohydrate utilization, cell growth (protein), and fermentation acid production. B. fibrisolvens 49, H17c, AcTF2, and D1 grew almost as well on one or more of the ...
متن کاملOxaloacetate Synthesis in Butyrivibrio fibrisolvens.
Phosphoenolpyruvate carboxykinase (adenosine 5'-triphosphate) was the only enzyme capable of carboxylating pyruvate or phosphoenolpyruvate that could be demonstrated in sonicated cells or cell-free extracts of a group 1 butyrivibrio.
متن کاملDegradation and utilization of xylan by the ruminal bacteria Butyrivibrio fibrisolvens and Selenomonas ruminantium.
The cross-feeding of xyland hydrolysis products between the xylanolytic bacterium Butyrivibrio fibrisolvens H17c and the xylooligosaccharide-fermenting bacterium Selenomonas ruminantium GA192 was investigated. Cultures were grown anaerobically in complex medium containing oat spelt xylan, and the digestion of xylan and the generation and subsequent utilization of xylooligosaccharide intermediat...
متن کاملProteolytic activity of the ruminal bacterium Butyrivibrio fibrisolvens.
The proteolytic activity of Butyrivibrio fibrisolvens, a ubiquitously distributed bacterial species in the gastrointestinal tracts of ruminants and other mammals, was characterized. The relative proteolytic activity (micrograms of azocasein degraded per hour per milligram of protein) varied greatly with the strain: 0 to 1 for strains D1, D16f, E21C, and X6C61; 7 to 15 for strains IL631, NOR37, ...
متن کاملBacteriocin-like activity of Butyrivibrio fibrisolvens JL5 and its effect on other ruminal bacteria and ammonia production.
When ruminal bacteria from a cow fed hay were serially diluted into an anaerobic medium that had only peptides and amino acids as energy sources, little growth or ammonia production was detected at dilutions greater than 10(-6). The 10(-8) and 10(-9) dilutions contained bacteria that fermented carbohydrates, and some of these bacteria inhibited Clostridium sticklandii SR, an obligate amino acid...
