Abstract
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 (6-deoxymannose) but not DNA. Organic acids produced from growth on hexoses and pentoses included acetate, propionate, lactate, and succinate. The isolates were identified as Selenomonas ruminantium subsp. lactilytica on the basis of morphology, substrate specificity, and other biochemical characteristics. Several characterized species of ruminal bacteria were also screened for growth on 2DR, with only one strain (S. ruminantium PC-18) found able to grow on 2DR. Ethanol was produced by 2DR when strains were grown on ribose or 2DR.
