Abstract: The black odor problems in the urban river of current China are in need to be solved urgently. In recent years, the insuit polluted sediment remediation technology of nitrateinduced indigenous microbial promoting was focused among many researchers. However, attention on the key reaction of sulfur autotrophic denitrification (SAD) was comparatively rare. The application research situations of SAD in the field of environmental pollution control were firstly introduced in this paper. Then the characters, the course of SAD, the production and accumulation byproducts (N2O、NO-2) reaction in sediment were discussed, as well as the research progress in population ecology characters and the population ecological relation between NRSOB and SRB. In addition, the some scientific problems in these researches which are not clear now were pointed out in the text. Finally, it was proposed that the research work of the denitrification process and mechanism of molecular ecology on sulfur autotrophic denitrification in the blackodor river sediment were important to the development of black odor control research work in the river of China.

Key words: blackodor sediment, nitrate, sulfur autotrophic denitrification, NR-SOB, SRB
