“…The results from continuous experiments revealed that the NRR remarkably declined from 0.61 to 0.25 kg N/m 3 d within 14 days on addition of 60 mg/L CTC owing to reduction in the relative abundances of AOB and AnAOB in the reactor. Although the inhibition of nitritation-anammox performance by CTC was irreversible, with the addition of fresh anammox sludge into the reactor, the NRR recovered to 0.09 ± 0.03 kg N/m 3 d (Yao et al 2018).…”

“…Additionally, various investigations have indicated that antibiotic inhibition increases with prolonged exposure time. For example, Yao et al (2018) showed that AnAOB were less sensitive to chlortetracycline stress than ammonium oxidizing bacteria (AOB) initially, but after 10 days, a synchronous increase of NH 4 + -N and NO 2 − -N E.J. Ozumchelouei et al: Effects of antibiotics on anammox process in wastewater was found.…”

“…Ozumchelouei et al: Effects of antibiotics on anammox process in wastewater was found. The accumulation of NO 2 − -N suggested that chlortetracycline remarkably suppressed AnAOB activity with elevated exposure time, as this antibiotic is a growth inhibitor (Yao et al 2018). , while studying the acute and chronic impact of OTC on the anammox process, obtained the halfmaximal inhibitory concentration (IC 50 ) of 517.5 mg/L in batch experiments, indicating that low levels of OTC had no effect on anammox in a short period, while in a longterm test, 50 mg/L OTC significantly reduced the NRR from 12.4 to 2 kg N/m 3 d within 26 days, demonstrating severe suppression of anammox performance by OTC due to cell lysis and growth inhibition of AnAOB.…”

“…The performance of partial-nitritation anammox was also investigated in multifarious studies. For example, Yao et al (2018) evaluated the short-and long-term influences of chlortetracycline (CTC) on the nitritation-anammox process. The IC 50 of CTC on the nitritation-anammox process was 278.91 mg/L in a short period of 12 h, suggesting that low levels of CTC had no significant impact on nitritation-anammox in a short time, as this antibiotic is a growth inhibitor.…”

Anaerobic ammonium oxidation (anammox) has recently become of significant interest due to its capability for cost-effective nitrogen elimination from wastewater. However, anaerobic ammonia-oxidizing bacteria (AnAOB) are sensitive to environmental changes and toxic substances. In particular, the presence of antibiotics in wastewater, which is considered unfavorable to the anammox process, has become a growing concern. Therefore, it is necessary to evaluate the effects of these inhibitors to acquire information on the applicability of the anammox process. Hence, this review summarizes our knowledge of the effects of commonly detected antibiotics in water matrices, including fluoroquinolone, macrolide, β-lactam, chloramphenicol, tetracycline, sulfonamide, glycopeptide, and aminoglycoside, on the anammox process. According to the literature, the presence of antibiotics in wastewater could partially or completely inhibit anammox reactions, in which antibiotics targeting protein synthesis or DNA replication (excluding aminoglycoside) were the most effective against the AnAOB strains.

“…To further address the shortcomings of those traditional nitrogen removal methods, new principles and strategies have been proposed, such as partial nitrification-denitrification [8][9][10][11], anaerobic ammonium oxidation (anammox) [12][13][14], and simultaneous nitrification and denitrification (SND) [15][16][17]. These approaches are based on the fact that ammonium-oxidizing bacteria (AOB) convert ammonium into an intermediary compound, nitrite, which is then transformed to nitrogen gas by autotrophic denitrification, heterotrophic denitrification and anammox [18,19]. These processes have been proven to be more energy-efficient than existing alternatives.…”

The development of efficient and low-cost wastewater treatment processes remains an important challenge. A microaerobic up-flow oxidation ditch (UOD) with micro-electrolysis by waterfall aeration was designed for treating real municipal wastewater. The effects of influential factors such as up-flow rate, waterfall height, reflux ratio, number of stages and iron dosing on pollutant removal were fully investigated, and the optimum conditions were obtained. The elimination efficiencies of chemical oxygen demand (COD), ammonia nitrogen (NH 4 + -N), total nitrogen (TN) and total phosphorus (TP) reached up to 84.33 ± 2.48%, 99.91 ± 0.09%, 93.63 ± 0.60% and 89.27 ± 1.40%, respectively, while the effluent concentrations of COD, NH 4 + -N, TN and TP were 20.67 ± 2.85, 0.02 ± 0.02, 1.39 ± 0.09 and 0.27 ± 0.02 mg l −1 , respectively. Phosphorous removal was achieved by iron–carbon micro-electrolysis to form an insoluble ferric phosphate precipitate. The microbial community structure indicated that carbon and nitrogen were removed via multiple mechanisms, possibly including nitrification, partial nitrification, denitrification and anammox in the UOD.

Anaerobic ammonium oxidation (anammox) is one of the most promising processes for the treatment of ammonium-rich wastewater. It is more effective, cheaper, and more environmentally friendly than the conventional process currently in use for nitrogen removal. Unfortunately, anammox bacteria are sensitive to various substances, including heavy metals and organic matter commonly found in the wastewater treatment plants (WWTPs). Of these deleterious substances, antibiotics are recognized to be important. For decades, the increasing consumption of antibiotics has led to the increased occurrence of antibiotics in the aquatic environment, including wastewater. One of the most important issues related to antibiotic pollution is the generation and transfer of antibiotic resistance bacteria (ARB) and antibiotic resistance genes (ARGs). Here, we will discuss the effect of short- and long-term exposure of the anammox process to antibiotic pollutants; with a special focus on the activity of the anammox bacteria, biomass properties, community structures, the presence of antibiotic resistance genes and combined effect of antibiotics with other substances commonly found in wastewater. Further, the defense mechanisms according to which bacteria adapt against antibiotic stress are speculated upon. This review aims to facilitate a better understanding of the influence of antibiotics and other co-pollutants on the anammox process and to highlight future avenues of research to target gaps in the knowledge.
