Isolation and characterization of Selenomonas ruminantium strains capable of 2-deoxyribose utilization.
Microbes from ruminal contents of cattle were selectively enriched by using 2-deoxyribose (2DR) as a substrate for growth. Bacterial isolates growing on 2DR were gram-negative, curved, motile rods. The isolates grew on a broad range of substrates, including deoxyribose, glucose, ribose, mannitol, and lactate as well as ribonucleosides and deoxyribonucleosides. The strains also grew on rhamnose ...
متن کاملCharacterization of lateral flagella of Selenomonas ruminantium.
Selenomonas ruminantium produces a tuft of flagella near the midpoint of the cell body and swims by rotating the cell body along the cell's long axis. The flagellum is composed of a single kind of flagellin, which is heavily glycosylated. The hook length of S. ruminantium is almost double that of Salmonella.
متن کاملFactors affecting lactate and malate utilization by Selenomonas ruminantium.
Lactate utilization by Selenomonas ruminantium is stimulated in the presence of malate. Because little information is available describing lactate-plus-malate utilization by this organism, the objective of this study was to evaluate factors affecting utilization of these two organic acids by two strains of S. ruminantium. When S. ruminantium HD4 and H18 were grown in batch culture on DL-lactate...
متن کاملUtilization of nucleic acids by Selenomonas ruminantium and other ruminal bacteria.
Species of ruminal bacteria were screened for the ability to grow in media containing RNA or DNA as the energy source. Bacteroides ruminicola D31d and Selenomonas ruminantium HD4, GA192, and D effectively used RNA for growth, but not DNA. B. ruminicola D31d was able grow on nucleosides but not on bases or ribose. The S. ruminantium strains were able to grow when provided with either nucleosides...
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...
