“…The removal of ammonium nitrogen is often neglected. Recently, many bacteria have been found to be capable of HN‐AD, implying that NH 4 + ‐N in water can be completely removed under aerobic conditions. To reveal the ammonium removal ability of the enriched bacterial consortium, the effects of different carbon to nitrogen mass ratios on BPF degradation and ammonium removal were investigated when BPF was used as sole carbon source (Fig.…”

“…For Salmonella enterica , genes encoding nitrate, nitrite and nitric oxide reductases can be found in GenBank, implying that this species can remove nitrogen by an aerobic denitrification process. Some Enterobacter , Citrobacter and Pseudomonas strains were reported to be capable of aerobic denitrification . Especially, Enterobacter and Pseudomonas strains exhibited good HN‐AD abilities .…”

“…However, this conventional method gives a low rate of nitrification, and needs a large space for aerobic and anoxic tanks . Based on these limitations, some novel nitrogen removal technologies have been developed in the past few years . The simultaneous heterotrophic nitrification–aerobic denitrification (HN‐AD) process has received increasing attention.…”

“…To date, many HN‐AD bacteria have been isolated and exhibit good performance for nitrogen removal under various conditions, even including low temperature or high salt condition . These HN‐AD bacteria generally remove nitrogen by using readily biodegradable carbon sources such as glucose, sodium acetate, sodium succinate, sodium citrate and corn flour . In fact, refractory aromatic hydrocarbon pollutants and nitrate/ammonia are commonly found in wastewaters .…”

BACKGROUND Traditional aerobic autotrophic nitrification and anoxic heterotrophic denitrification have many limitations. Recently, the simultaneous heterotrophic nitrification–aerobic denitrification (HN‐AD) process has received increasing attention. Thus, the possibility of the simultaneous removal of bisphenols and NH4+‐N via HN‐AD was investigated. RESULTS A bisphenols‐degrading bacterial consortium was enriched and capable of degrading 50 mg L−1 bisphenol A, 300 mg L−1 4,4‐dihydroxybenzophenone, 375 mg L−1 bisphenol F (BPF) and 10 mg L−1 bis(4‐hydroxyphenyl)sulfide under aerobic conditions. Further studies showed that the bacterial consortium could completely degrade 300 mg L−1 BPF and remove NH4+‐N at 35 °C with 150 rpm at the C/N ratio of over 10. Moreover, BPF mineralization and NH4+‐N reduction to N2 were observed. Clone library analysis indicated that Salmonella enterica, Enterobacter,Citrobacter and Pseudomonas could cooperate to degrade BPF and reduce NH4+‐N to N2. Among these species, the isolated Pseudomonas sp. HS‐2 was capable of simultaneous BPF degradation and NH4+‐N removal via HN‐AD. CONCLUSION The experimental results demonstrated that the enriched bacterial consortium and the isolated strain HS‐2 could simultaneously remove BPF and NH4+‐N via HN‐AD, indicating that this is a potential way for the treatment of wastewaters containing these compounds. © 2016 Society of Chemical Industry

“…become an increasingly serious problem worldwide, especially in arid and semiarid regions of China [9][10][11]. Reservoir water is the primary source of drinking water for many citizens, and nitrogen pollution may cause a significant deterioration in water quality and therefore threaten the safety of the drinking-water supply [9].…”

The effects of combined different strains on a simultaneous denitrification and biomineralization process were examined. The influence of sodium succinate concentration, pH, and hydraulic retention time on nitrate and hardness removal was evaluated in bioreactors. Experimental results indicated that high nitrate and hardness removal efficiencies were obtained under optimum conditions. The community diversity was markedly influenced by the concentration of sodium succinate. The findings proved that Pseudomonas sp. H117 and Pseudomonas sp. H2 played a key role in the process of nitrate and hardness removal. The main component of sedimentation generated from the bioreactor was detected as calcium ion precipitation by scanning electron microscopy and X-ray diffraction.
