Departm ent ofMunicipal Engineering, WuhanUniversity, W uhan 430072 R eceived 29 April 2006; accepted 29N ovember 2006 A bstract: The effects of carbon source and C /N ratio on denitrification of aerobic denitrifier w ere investigated in the batch culture under aerobic env ironm ent. The results show ed that nitrate reductase activ ity w as influenced by different carbon source. The nitrogen rem oval rate by using succinate and acetate w as significantly higher than that by usingm alate. H ow ever, denitrification rate by u sing acetate w as slightly higher than that by u sing succinate, - - - in which a high denitrification rate ( NO ) of . 86m g g h was also achieved w ith acetate as the electron donor. Itw as found that nitro
