Discovery and structural characterization of lanthipeptides from soil and rumen bacteria
… a glimpse into the targeted screening of Actinobacteria for the production of lanthipeptides, which suggests additional structural diversity. The successful application of these methods increases the number of lanthipeptide compounds and systems, which ultimately allows for a deeper …

An appraisal of the equivalence of two media proposed for the isolation of cellulolytic rumen bacteria
… media proposed for the isolation of cellulolytic rumen bacteria were investigated. The inorganic medium containing rumen fluid gave greater total counts, greater cellulolytic counts, and a greater variety of morphological forms of cellulolytic rumen bacteria than the rich organic medium containing …

The Effect of Cellulolytic Rumen Bacteria or Their Cell-Free Extracts on the Germination of Euonymus americanus L.
… little success. However, treatment of seeds with rumen fluid containing viable microflora has been successful in stimulating germination. In the presence of the cellulolytic rumen bacterium. <em>Clostridium cellobioparum </em>ATCC 15832, seeds of <em>E. americanus</em> were stimulated to …

The cloning and characterization of a Butyrivibrio fibrisolvens H17c glnA regulatory element in E. coli
… anaerobic bacterium which occurs in the rumen of most ruminants. A key factor affecting the growth of this bacterium is the availability of nitrogen sources, particularly in the form of ammonia. The aims of this study were to attempt the isolation of a gene/genes involved in the …

The analysis of an enzyme (Ce1A) and a gene system (abg) involved in the utilization of lignocellulose in the rumen
… interest is the degradation of forage in the rumen and one research goal is to ultimately increase animal productivity through an improvement in lignocellulose utilisation. However, although the mechanisms behind lignocellulose utilisation are reasonably well understood, relatively little is …

The development of differential media for the isolation of proteolytic bacteria from the rumen
… media were adapted to the culture of proteolytic bacteria from the bovine rumen. Modifications were made in the double indicator dairy medium of Donovan and Vincent (SRBP) and in the medium of Hungate for rumen bacteria (SRP). Modifications included use of plant protein suspensions, casein, and …

The structure and function of a bovine salivary protein - BSP30b
… droplets, as observed by fluorescent microscopy. Bacteria extracted directly from rumen samples indicate that the GFP_BSP30b fusion protein binds to a small number of selected bacterial strains in vivo. These results suggest that BSP30b could have a specific range of lipid ligands and may play …

Effect of Yeast Supplementation During Various Stages of Beef Production
… there a difference in community structure for rumen bacteria; fecal α or β diversity were different on d 34. In experiment 3, late gestation cows (n = 97) were supplemented YP approximately 45 d prior to parturition. At parturition colostrum and blood samples (n = 30) were collected to …

Digestion and utilization of nutrients in diets containing feather meal and (or) supplemental fat by lactating dairy cows
… similar for all diets. No changes were seen in rumen pH, rumen ammonia-N, VFA's, or rumen bacteria AA. Intake and fecal output of total, essential, and non-essential AA were greater when cows were fed diets containing feather meal. However, flow of AA to the duodenum, AA absorbed, and AA …

Efficient utilization of Macadamia oil cake based diets in ruminants
Ruminants and rumen bacteria form a symbiotic relationship. However, because of nitrogen (N) inefficiency, this interdependent relationship loses energy and protein. Strategic feeding of ruminants with diets containing non-conventional feedstuffs appears to be a promising way to enhance proficiency …

Deoxyribonucleic acid restriction/modification systems and gene transfer strategies in Ruminococcus albus 8 and Ruminococcus flavefaciens FD-1
… to the use of recombinant DNA technologies with rumen bacteria is the establishment of a stable DNA transfer system. Research to date has shown that Ruminococcus can be classified as a genus resistant to transformation, and that electroporation may offer the only means to introduce foreign DNA. …

Rumen biohydrogenation of polyunsaturated fatty acids in high quality pasture
… second experiment to determine the effect of low rumen pH on biohydrogenation of C18 fatty acids. A standard ryegrass sample was incubated in nylon bags in the rumen of a dry cow fed low-quality lucerne silage, or in two milking cows fed with high-quality LUDF pasture, during four experimental …

The rumen microbial ecosystem during the transition period in dairy cows
Seven rumen cannulated Holstein cows were used from 3 weeks prepartum to 4 weeks postpartum to determine the relative abundance of 7 different species of ruminal microorganisms. The prepartum diet was based on corn silage. In the postpartum, diet included ground corn, grain by-products, and alfalfa …

TRACEABILITY OF MOUNTAIN CHEESES: IDENTIFICATION AND CHARACTERIZATION OF BIOCHEMICAL MARKERS
… dietary phytol of chlorophyll by the action of rumen bacteria. Since n-alkanes are important components of vegetable matrix, they are abundant in plant cuticular waxes and they are inert in the digestive tract of ruminants. Milk and cheese samples of highland origin were characterized by higher …

Influence of nutrition on the muscle transcriptome and ruminal microbiome in cattle
… diet, but these products may negatively impact rumen bacteria at high inclusion levels. Five ruminally-fistulated steers were used in a 5 × 5 Latin square design to determine the effects of increasing dietary fat and sulfur from (CDS) on the ruminal microbiome. Alpha-diversity and species …

Genetic and biochemical analysis of nitrogen metabolism in ruminal anaerobic bacteria: a comparison between ruminococcus albus 8 and prevotella ruminicola 23
… and biochemical pathways utilized by the rumen bacteria, Ruminococcus albus 8 and Prevotella ruminicola 23 during growth on, and metabolism of, different nitrogen sources. Both R. albus 8 and P. ruminicola 23 were grown using different nitrogen sources; ammonia, urea, or peptides for R. …
