Abstract

Molecular beacons are fluorescent probes developed for solution rather than membrane hybridization. We have investigated the utility of these probes to study rumen microbial ecology. Two cellulolytic species, Ruminococcus albus and Fibrobacter succinogenes, were tested. Membrane and solution hybridizations gave similar results in competition experiments with cocultures of R. albus 8 and F. succinogenes S85.

摘要

分子信标是为溶液而非膜杂交开发的荧光探针。我们研究了这些探针在瘤胃微生物生态学研究中的实用性。测试了两种纤维素分解菌,即白色瘤胃球菌和琥珀酸纤维杆菌。在白色瘤胃球菌8和琥珀酸纤维杆菌S85共培养物的竞争实验中,膜杂交和溶液杂交给出了相似的结果。
