Abstract—The effect of nitrite loading rate, organic carbon called mixotrophic denitrification [9]. It is reported that sulfide
category and loading rate was investigated on simultaneous and nitrate can be degraded by an isolated Thiobacillus
removal anic carbon, sulfide, nitrate and nitrite by the denitrificans, anic carbon exists. And nitrate can be
mixotrophic denitrification and desulfurization process. This reduced to nitrite and accumulate, when sulfide is oxidized to
simultaneous respiratory process could be explained in terms of sulfur and sulfate in almost equal proportions [10].

25mgC/(L⋅d) of acetate sodium were suitable for denitrification- Recently, t
