Abstract
In this study, variations of the organic and nitrogenous compounds in wastewater were investigated in a single reactorwith intermittent aeration. Over 90% of organic and nitrogen removals are accomplished with C/N ratio of 3 : 1 and 20/20 min ofaeration/non-aeration period. Longer non-aeration period on the aeration/non-aeration cycle showed more stable nitrogen removal,showing various microbial community in the reactor. From PCR-DGGE analysis, it is conclusive that Dysgonomonas mossii strainMelo40, Eubacterium sp. oral clone JN088, Uncultured bacterium clone SPESB2_718, and Bacterium enrichment culture clone LEare related with the organics and nitrogen oxidation. Uncultured Acidobacteria bacterium clone AKYG487, Lactobacillus harbinensisstrain FQ003, Erythrobacter litoralis strain Gi-3, Phytobacter diazotrophicus strain Ls8, and Mycobacterium sp. enrichment cultureclone GE10037biofNNA are distinctly appeared under denitrification condition.
