摘  要：
为了研究瘤胃非典型纤维降解细菌的发酵和纤维降解特性,试验选取已分离鉴定出的四株瘤胃纤维降解细菌,即拜氏梭菌、丁酸梭状芽孢杆菌、链球菌、肠球菌,分别培养72h后,测定其pH、产气量、纤维素酶活力、挥发性脂肪酸、氨氮浓度和菌体蛋白浓度。结果表明,4株瘤胃纤维降解细菌培养液的pH、羧甲基纤维素(CMC)酶活力、挥发性脂肪酸(VFA)浓度无显著差异(P>0.05),而在产气量、氨氮浓度、菌体蛋白浓度、滤纸酶活力、水杨苷酶活力和微晶纤维素酶活力,拜氏梭菌与肠球菌均高于链球菌与丁酸梭状芽孢杆菌(P<0.05)。试验结果提示,拜氏梭菌与肠球菌纤维降解特性较好。

摘  要：
To study fermentation characteristics and atypical fiber degradation of the rumen bacteria,four strains were isolated and identified,namely Clostridium beijerinckii,Clostridium butyricum,Streptococci,Enterococcus.They were selected to test their gas production,enzyme activity,volatile fatty acids,NH3-N and Bcp as well as pH after being cultured for 72 hours.The results showed that the pH,CMC enzyme activity,VFA of four rumen fiber degrading bacteria revealed no significant difference(P>0.05).The value of gas production,NH3-N,Bcp,filter paper enzyme activity,salicin enzyme activity,microcrystalline cellulose enzyme activity of Clostridium beijerinckii and Enterococcus were higher than that of Streptococci and Clostridium butyricum(P<0.05).The results displayed that Clostridium beijerinckii and Enterococcus enterococci performed better fermentation characteristics.
