摘要:
为探索不同植被根际可培养黏细菌与未培养黏细菌的多样性,采用传统的辅助菌诱导方法,对样品的黏细菌进行分离纯化,通过形态特征结合16S rDNA基因的序列分析,确定黏细菌菌株的系统分类地位;利用基于黏细菌特异性引物的变性梯度凝胶电泳(denaturing gradient gel electrophoresis,DGGE)分析黏细菌的多样性。结果显示,从不同植被根际土壤中共分离得到19株,初步鉴定为黏球菌属(Myxococcus)11株,珊瑚球菌属(Corallococcus)13株,孢囊杆菌属(Cystobacter) 2株,多囊菌属(Polyangium)1株,其中,红树林分离得到的黏细菌种类最多,共7株;樟木最少,为2株。PCR-DGGE分子指纹图谱技术对其黏细菌多样性结果显示,花梨木、铁木、亚热带常绿阔叶林、针叶林、红树林、樟木根际土壤中黏细菌的物种丰度分别为16、24、34、26、30、24,多样性指数分别为2.10、2.53、3.49、2.62、2.77、2.73。DGGE指纹图谱显示,越南不同植被根际土壤存在大量的未培养黏细菌,其技术研究黏细菌多样性比传统分离纯化的方法方便、快速。本研究为黏细菌开发利用和多样性研究提供理论与技术参考依据。
