Nitrate reduction by Citrobacter diversus under aerobic environment

Abstract: A new aerobic denitrifier, Citrobacter diversus, was isolated from both nitrification and denitrification sludge. To monitor the variation in the concentration of nitrogen oxides, aerobic denitrification by C. diversus was carried out in a batch reactor. When the nitrate concentration was greater than 180 mg N l(-1), the nitrate reduction rate became stable. The effect of the C/N ratio on the denitrification activity was also investigated. The results showed that the optimum denitrification activity was obtain… Show more

“…Generally, denitrification is an anaerobic or anoxic process; however a complete nitrate removal was reported even at a DO concentration of 5 mgO 2 /l [7,12]. In this study, DO diminished from 5.50 to 0.40 mgO 2 /l during the first 4 h. During 3 days of continuous flow, the DO increased to 2.5 mgO 2 /l and remained at that level (Fig.…”

“…The nature and the amount of the organic substrate used as exogenous carbon source plays an important role in the success and price of denitrification. Various substrates have been used in many studies and a whole variety of compounds, mostly methanol [3,8,9], acetate [4,6,7], and ethanol [10]. Some studies used nutrient broth [11] and tryptic soy broth [12].…”

“…This may be attributed to the proliferation of GAD3 prior to the nitrification process. The occurrence of the lag phase is also found in aerobic denitrifiers [6]. The variance in metabolism by different subclass of proteobacteria may be the possible reason for it and the proliferation by assimilation may take place before the catabolism process.…”

“…Later, some aerobic denitrifiers were isolated by the same method. Frette et al [19] isolated 16 denitrifiers from an intermittent anaerobic/aerobic wastewater treatment tank that denitrified under either aerobic or anaerobic condition. After 40 h incubation, 90.8% of the total nitrogen was removed and the cell yield increased five-fold.…”
