%X The community structure and the behavior characteristic of the activated sludge in mineral substrate and in basic substrate conditions are studied. The result shows notable difference between the two conditions in regard to community structure and whole characteristic of the microorganism. When imposed to high concentration NO~-_3, the microorganism rapidly changes its community structure to adapt the new environment and tries to keep its intrinsic microbial diversity. Furthermore, some bacteria species are confirmed by comparing the sequences of several pieces of 16S rDNA V3 fragments with the DNA sequences in GeneBank(NCBI).
