Isolating and Denitrification Activity of the Dominant Bacterium in Chaohu Wetland

摘要：

This passage took soil samples from Chaohu wetland at 1.5m buried depth. Then isolated the dominant bacteria and studied its denitrification activity under the condition of different carbon sources (methanol, ethanol and acetic acid) and C/N (3:1, 5:1, 10:1). The results suggested: (1) the nitrate removal rate of isolated strain reached 90％ (named as D9); (2) under the condition of C:N was 1:1, acetic acid was the best carbon source; (3) taking acetic acid as the sole carbon source, the best C:N was 3:1.These results can provide the base for the restoration of nitrate pollution in groundwater and the prevention of Lake Eutrophication.
