Degradation of lucerne stem cell walls by five rumen bacterial species
The rumen bacterial strains Butyrivibrio fibrisolvens Hl7c, Fibrobacter succinogenes S8S, Lachnospira multiparus 4°, Ruminococcus albus 7 and R. flavefaciens FD-l were compared individually and as a five-species mixture with a rumen inoculum for their ability to degrade lucerne (Medicago sativa L.) stem cell wall polysaccharides. Two maturity stages oflucerne (bud and full flower) were utilized...
متن کاملDetermining the culturability of the rumen bacterial microbiome
The goal of the Hungate1000 project is to generate a reference set of rumen microbial genome sequences. Toward this goal we have carried out a meta-analysis using information from culture collections, scientific literature, and the NCBI and RDP databases and linked this with a comparative study of several rumen 16S rRNA gene-based surveys. In this way we have attempted to capture a snapshot of ...
متن کاملFormation of bacterial microcolonies on feed particles in the rumen.
Examination of particulate feed that had been digested in vivo in the rumen, and of the leaves of specific legumes that had been digested in vitro by a mixed population of rumen bacteria, showed that very extensive glycocalyx-enclosed bacterial microcolonies developed on many of the available surfaces. Some of these adherent bacteria colonized a surface almost exclusively and attracted another ...
متن کاملStudies on Bovine Rumen Bacterial Urease 1
The propert ies of rumen urease were studied. In the absence of high concentrations of dithiothreitol enzyme activity was rapidly lost; in its presence, the enzyme could be solubilized and purified in high yield. Maximum activity was observed between pH 7 and 8.5. The Km for urea with partially purified enzyme was .004 M with Vmax of 300 to 400 #moles/mg/hr. No divalent metal ion requirement or...
متن کاملComparison of the sphingolipid content of rumen Bacteroides species.
Ten strains of Bacteroides ruminicola were found to contain phosphosphingolipids. Four strains of Bacteroides amylophilus and one strain each of Bacteroides succinogenes and Bacteroides sp. were devoid of phosphosphingolipids.
