纤维素降解细菌的分离、鉴定及其系统发育分析

Isolation,Identification and Phylogenetie Analysis of the Cellulase-producing Strain

采用选择性培养基从不同地区土壤中筛选得到具有纤维素分解能力的菌株共65株,从中选取纤维素降解能力较高的细菌1株并对其进行表型、生理生化和分子鉴定。结果表明株菌NJ2-008属于不动杆菌属(Acinetobacter),与乙酸钙不动杆菌(Acinetobacter calcoacetirum)的序列相似度达98%。

The author screened the cellulase- producing strain from the soil of different sites by the selective medium, and then identified the strain based on their phenotype, phisiological - biochemical property and molecular identification. The result showed that strain N J2-008 is closely related to Acinetobacter calcoacetirum with 98% sequence similarity. Therefore, strain NJ2 -008 was identified as the species Acinetobacte.
