The phylogenetic diversities of bacteria in a gravel contact oxidation reactor,a novel equipment for excess sludge decrement,were studied by constructed 16S rDNA library,PCR-based molecular surveys of environmental 16S rDNA genes.Total 80 16S rDNA gene clones were retrieved and evaluated their phylogenetic diversity.46 clones(17 OTUs) were isolated from the biofilm,and 34 clones(12 OTUs) were from the inner sludge.The measured bacteria diversities were evaluated by diversity indices,richness indices,evenness indices and dominance indices.The evaluation results indicated that both diversity and dominance of the bacteria isolated from biofilm were higher than inner sludge.
