In the present study, a novel Pseudomonas sp. W1 was characterized in terms of its ability to perform nitrate removal coupled with anaerobic Fe2+ oxidation under autotrophic growth condition. The effects of operating parameters with respect to the initial solution pH, temperature and initial Fe2+ concentration on nitrate removal were investigated by central composite design. Based on the results of response surface methodology, the maximal nitrate removal efficiency was achieved under the following conditions: pH 7.0, temperature 30 °C and initial Fe2+ concentration 1,100 mg L−1. Under this optimal condition and with an initial NO3−-N concentration of 55 mg L−1, this strain could remove NO3−-N with 90% reduction of NO3−-N, corresponding to oxidizing Fe2+ with 71% oxidation of Fe2+ after 7 days of incubation. The result of kinetic evaluation indicated that this bacterium showed significant substrate affinity to both NO3−-N and Fe2+.

A continuous upflow biofilm reactor packed with ceramsite was constructed for nitrate removal under an anaerobic atmosphere without an organic carbon source. Denitrifying bacteria, Pseudomonas sp. W1, Pseudomonas sp. W2 and Microbacterium sp. W5, were added to the bioreactor as inocula. Nitrate concentration, nitrite accumulation and nitrogen removal efficiency in the effluent were investigated under various conditions set by several parameters including pH, hydraulic retention time (HRT), ratios of carbon to nitrogen (C/N) and temperature. The results illustrated that the maximum removal efficiency of nitrogen was 85.39%, under optimum reaction parameters, approximately pH 6.5–7, HRT = 48 hours and C/N = 13.1:1 at temperature of 30 °C, which were determined by experiment.
