Mud volcanoes in Mainland China have not been extensively studied, particularly the microbial community structure. In the present study, we provided the first comparative analysis of the microbial community diversity of Dushanzi (DSZ) and Baiyanggou (BYG) mud volcanoes (MVs), especially for archaea. The universal bacterial and archaeal primers for the 16S rRNA genes were used to identify the microbial community. The results demonstrated that the BYG mud volcano bacterial community diversity is higher than that of the DSZ mud volcano, while the archaeal community diversity of BYG mud volcano is lower than that of the DSZ mud volcano. Phylogenetic analysis indicated that the bacterial and archaeal community structure was significantly different between the DSZ and BYG mud volcanoes. Most of the archaea recovered from DSZ identified in these mud volcanoes are anaerobic or highly thermophilic while recovered from BYG was identified as halobacteria consistent with their particular geographical nature. Moreover, many bacterial and archaeal genera, such as Methanomicrobia, sulfur-oxidizing symbiont bacterium and Alcanivorax sp., have been detected in these two mud volcanoes. The results of the present study contribute greatly to information concerning the species origin and formation mechanisms of mud volcanoes, providing a basis for species accumulation and exploration in the margins of Junggar Basin.
Key words: Mud volcano, community structure, Junggar Basin.
