采用变性梯度凝胶电泳(DGGE)分析技术,对青海农村户用沼气池内细菌及古菌群落结构进行分析.结果表明,沼气池含有丰富的细菌及古菌类群,且泥样间的细菌和古菌的群落结构存在差异.4个户用沼气池发酵系统中,细菌分属于5个门,优势类群为拟杆菌门(Bacteroidetes)、厚壁菌门(Firmicutes)和变形菌门(Proteobacteria).在属分类水平上,属于24个类群,最优势类群为理研菌科佩特里单胞菌属(Petrimonas)、假单胞菌属(Pseudomona)、泰氏菌属(Tissierella)和梭菌属(Clostridium).同时,沼气池发酵系统中古菌主要包括热丝菌属(Thermofilum)、甲烷短杆菌属(Methanobrevibacter)、甲烷囊菌属(Methanoculleus)、产甲...

The microbial community composition in rural household biogas digesters of Qinghai was investigated with polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technology. The results showed that the diversity of bacteria and archaea were rich, and the shift of microbial community was obvious in digesters. The bacterial communities in four biogas digesters were classified into five phyla, Bacteroidetes, Firmicutes and Proteobacteria were identified to be dominant. At genome level, belonging to twenty-four communities, Petrimonas, Pseudomona, Tissierella and Clostridium we...
