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 or ribose but not bases. Strains of S. ruminantium, but not B. ruminicola D31d, were also able to use nucleosides as nitrogen sources. These data suggest that RNA fermentation may be a general characteristic of S. ruminantium.
筛选瘤胃细菌物种,以检测其在含有RNA或DNA作为能源的培养基中生长的能力。瘤胃栖粪杆菌D31d和反刍月形单胞菌HD4、GA192及D能有效利用RNA进行生长,但不能利用DNA。瘤胃栖粪杆菌D31d能够在核苷上生长,但不能在碱基或核糖上生长。当提供核苷或核糖而非碱基时,反刍月形单胞菌菌株能够生长。反刍月形单胞菌菌株而非瘤胃栖粪杆菌D31d也能够利用核苷作为氮源。这些数据表明RNA发酵可能是反刍月形单胞菌的一个普遍特征。
