“…Moreover, Clostridia was the most abundant class initially, accounting for about 38% of the total bacterial abundance, but it dropped to 6 and 9% in the Control and Ammonia groups. Certain Clostridia species have been found to function as syntrophic acetate-oxidizing bacteria (SAOB), which can decompose acetic acid into CO 2 and H 2 . The abundance of Thermotogae was 11 and 8% in the Control and Ammonia groups, which seemed to decrease due to ammonia toxicity.…”

“…15,16 For example, Liu et al 17 increased methane production by 41.7% after adding 5 mg/g VS glutathione and found that glutathione can raise the activities of microorganisms and enzymes related to AD under high ammonia conditions. Yang et al 18 studied how to alleviate the inhibition of ammonia nitrogen by bioaugmentation. Finally, they increased methane production by 39−49% through the well-constructed consortia (relative abundance Methanosarcina > 60%, Clostridia > 60%).…”

Nitrogenous organic matter could be converted into ammonia nitrogen during anaerobic digestion (AD) which could lead to the inhibition of methane production. Therefore, it is crucial to investigate the effect of ammonia stress on AD. In this study, the addition of ammonia nitrogen concentration of 1.5 g N/ L led to an obvious extended lag-period time of the AD with propionic acid or n-butyric acid as the sole substrate, while it showed no effect on the AD of acetic acid, indicating that the biotransformation of propionic acid and butyric acid might be more susceptible under low inhibitory ammonia stress. Analysis of the microbial consortia revealed that the community composition of bacteria and archaea was not obviously affected by a low inhibitory ammonia stress. Metatranscriptomic analysis showed that the enzymes related to the biotransformation of propionic and butyric acids were more susceptible to ammonia toxicity than those corresponding to acetoclastic methanogenesis. During protein synthesis, the expression of RNA polymerase and the subunits of ribosomes, which affected the transcription process, were significantly down-regulated. Additionally, ammonia toxicity caused DNA damage in microorganisms and triggered the SOS response of microorganisms. This study provided new insights for further understanding of the mechanism of ammonia stress at a low inhibitory level.

“…Mechanisms of ammonia inhibition include destruction of enzyme activity, pH change inside the cell and cell dehydration because of high osmotic pressure [11,13,14]. Many methods to alleviate ammonia inhibition in AD have been reported recently, such as bioaugmentation [15,16], struvite precipitation [17], supplementation of certain trace element [18,19], adjustment of C:N ratio [20], supplementation of via nano-bubble water [21] and supplementation of magnetite and polyurethane foam carrier [22].…”

Continuous stirred bioelectrochemical system (CSBES), consisting of anaerobic digestion reaction zone (ADRZ) and bioelectrochemical reaction zone (BERZ), was constructed to investigate the ammonia inhibitory effects on the performance of electricity generation and wastewater treatment. Continuous experiments were conducted with ammonia concentration ranging from 300 mg/L to 1200 mg/L. As the ammonia concentration increasing from 300 mg/L to 900 mg/L, both of the maximum power densities and the COD removal increased. When the ammonia concentration reached to 1200 mg/L, the maximum power densities of the four cells decreased by 55.7%, 58.9%, 58.0% and 60.6% in comparison with that under ammonia concentration of 900 mg/L. The COD removal reduced to 71.2 ± 1.4%, leading to COD concentration in the effluent increased to 1758 ± 93 mg/L. Electrochemical measurements revealed that the deterioration of anode performance caused the reduction of power generation. The conductivity control experiment showed that the toxic effects of high ammonia concentration on exoelectrogens caused performance deterioration of the CSBES. The threshold ammonia concentration that triggered the inhibition effect on exoelectrogens in CSBES was 1200 mg/L, and the anaerobic consortium in ADRZ could tolerant to higher ammonia concentration than the exoelectrogens in BERZ.

The “dual-carbon” strategy promotes the development of the wastewater treatment sector and is an important tool for leading science and technology innovations. Based on the global climate change and the new policies introduced by China, this paper described the new needs for the development of wastewater treatment science and technology. It offered a retrospective analysis of the historical trajectory of scientific and technological advancements in this field. Utilizing bibliometrics, it delineated the research hotspots within wastewater treatment, notably highlighting materials genomics, artificial intelligence, and synthetic biology. Furthermore, it posited that, in the future, the field of wastewater treatment should follow the paths of technological innovations with multi-dimensional needs, such as carbon reduction, pollution reduction, health, standardisation, and intellectualisation. The purpose of this paper was to provide references and suggestions for scientific and technological innovations in the field of wastewater treatment, and to contribute to the common endeavor of moving toward a Pollution-Free Planet.
