- 摘要:
- 为从环境中筛选高效纤维素降解菌,并研究其产酶能力,从农村堆肥粪堆的底部土壤中分离、纯化获得了1株纤维素降解菌NY06,进行了透明圈、滤纸崩解、CMC酶和FPA酶活力的测定。结果表明:与对照菌株相比,菌株NY06处理的透明圈出现较早,透明圈更大,滤纸崩解效果更好;菌株NY06的CMC酶和FPA酶活的最大OD值分别为0.158和0.108,均大于对照菌株;经初步鉴定,菌株NY06为枯草芽孢杆菌。
- Abstract:
- In order to screen the efficient cellulose degradation bacteria from environment,and study the enzyme production ability,a cellulose degrading bacteria NY06 was isolated from soil at the bottom of the dunghill rural compost.By measurements using transparent ring,filter paper disintegration,CMC enzyme and FPA enzyme activities,NY06 was preliminarily identified as a member of the genus Bacillus subtilis sp.The results showed that treatment inoculated with stain NY06 showed early appearance of a transparent ring and also the transparent ring was larger,compared with the control bacteria,and results of the filter paper disintegration was better.The CMC enzyme and FPA enzyme activities of strain NY06 had the maximum OD values of 0.158 and 0.108,respectively,and they were higher than the control strain.
