     influence of the frequently used carbon sources in nitrate removal processes were evaluated in a lab-scale biofilm reactor. the no3–n removal efficiency was in the order acetate > glucose > methanol > ethanol. acetate-fed biofilm reduced nearly 100% no3–n with negligible amount of no2–n accumulation. although 99% no3–n was reduced in the glucose-fed biofilm, substantial nh3–n and no2–n accumulated. methanol-fed biofilm reduced 72% of no3–n with accumulation of 2.2 mg l−1 of no2–n, while biofilm formed in presence of ethanol showed 61% reduction in no3–n although relatively higher ratio of denitrifiers were observed. acetate and ethanol-fed biofilm displayed characteristic biofilm architecture with voids, but the former had relatively higher thickness and diffusion distance. in presence of glucose and methanol, a confluent biofilm without characteristic voids was formed. pseudomonas sp. numerically dominated the acetate and ethanol-fed biofilm, while enterobacter sp. andmethylobacillus sp., were abundant in glucose and methanol biofilms respectively.
