ABSTRACT: The bacterial composition of the pink mat was studied by culture-independent approach. 23 complete 16S rDNA sequences were obtained. According to the sequences alignment and analysis of comparability, the bacteria of the pink mat was consisted of Proteobacteria, Firmicutes, Bacteroidetes, Actinobacter, Deinococcus-thermus, Aquificals. And compared with bacterial composition of the mats from Octopus spring in Yellowstone Park and Haegindi and Fluidir spring, Olkelduhals, Grensdalur spring in Iceland, the pink mat in spectacles spring had highest bacterial diversity among them because it perhaps included lots of bacteria at lower temperature. And the result indicated the same community lived in the same niche and Aquficales was dominant group among bacterial composition of the mat in higher temperature and near-neutral hot spring.
