| 摘 要： | 试验从蒙古绵羊瘤胃中分离出3株厌氧细菌，通过细菌纤维降解性试验发现3株菌皆具有纤维降解能力；通过革兰氏染色试验发现3株菌均为革兰氏阳性菌；通过生理生化试验和16S rDNA基因序列测定及同源性分析，最终确定分离的3株菌分别为牛链球菌（Streptococcus bovis）、婴儿链球菌（Streptococcus infantarius）和粪肠球菌（Enterococcus faecium），编号为E1、E2和E3。

| Abstract: | Three strains of anaerobic bacteria were isolated from the rumen of the Mongolian sheep. The bacterial cellulose degradation detection test showed that all of the bacteria have fiber degradation ability.All of the bacteria were gram-positive bacteria according to the gram stain test.After the physiological and biochemical test， and determination of 16S rDNA gene sequences and the homology analysis，the three strains of bacteria turned out to be Streptococcus bovis，Streptocococcus infantarius and Enterococcus faecium，and were named as E1，E2 and E3，respectively. |
