“…Planctomycetes is a typical phylum representing anammox microorganisms [54]. It has demonstrated that Planctomycetes could be used for the initial breakdown of various highly complex polysaccharides, thus making them available to other microbiomes and then playing a key role in the biogeochemical transformation of the carbon and nitrogen cycles [55]. The increasing abundance was associated with the improvement performance of nitrogen removal during the recovery stage.…”

The mainstream application of the anammox process is often hindered by its long recovery phase and instability under disturbance. In this study, a lab-scale anammox sequencing biofilm batch reactor (SBBR) was rapidly recovered within 85 days by gradually increasing the influent nitrogen concentration, and the total inorganic nitrogen (TIN) removal efficiency achieved 83.44 ± 0.03%. During the recovery process, the nitrogen removal rate (NRR) increased from 0.05 to 0.34 kg/(m3·d), with the nitrogen loading rate (NLR) changing from 0.08 to 0.40 kg/(m3·d) in the anammox system. The activities of hydrazine oxidase (HZO) in the biofilm also increased from 0.17 to 10.80 μmol Cyt-c/(g VSS·s). Also, the dominant anammox genera in the biofilm were Candidatus Kuenenia and Candidatus Brocadia. The results of this study suggested that an SBBR–anammox system filled with a microbial carrier could facilitate the enrichment of anammox bacteria and contribute to performance recovery.

“…Moreover, Planctomycetes contain bacteria related to Anammox (Bae et al 2010). Planctomycetes not only has the function of Anammox, but also may play denitrification function (Du et al 2020, Ishimoto et al 2020, Kumar et al 2020, Park et al 2020, Vipindas et al 2020.…”

Four subsurface flow constructed wetlands (SFCWs) filled with different substrates including ceramsite, ceramsite+pyrite, ceramsite+ferrous sulfide, and ceramsite+pyrite+ferrous sulfide (labeled as SFCW-S1, SFCW-S2, SFCW-S3, and SFCW-S4) were constructed, and the removal of nitrogen and phosphorus by these SFCWs coupled with intermittent aeration in the front section was discussed. The key findings from different substrate analyses, including nitrification and denitrification rate, enzyme activity, microbial community structure, and the X-ray diffraction, revealed the nitrogen and phosphorus removal mechanism. The results showed that the nitrogen and phosphorus removal efficiency for SFCW-S1 always remains the lowest, and the phosphorus removal efficiency for SFCW-S4 is recorded as the highest one. However, after controlling the dissolved oxygen by intermittent aeration in the front section of SFCWs, the nitrogen and phosphorus removal efficiencies of SFCWs-S2 and S4 becomes higher than those of SFCW-S1, and SFCW-S3. It was noticed that the pollutants were removed mainly in the front section of the SFCWs. Both precipitation and adsorption on the substrate were the main mechanisms for phosphorus removal. A minute difference of nitrification rate and ammonia monooxygenase activity was observed in the SFCWs aeration zone. The denitrification rates, nitrate reductase, nitrite reductase, and electron transport system activity for SFCW-S2 and SFCW-S4 were higher than those detected for SFCW-S1 and SFCW-S3 in the non-aerated zone. Proteobacteria was the largest phyla found in the SFCWs. Moreover, Thiobacillus occupied a large proportion found in SFCW-S2, and SFCW-S4, and it played a crucial role in pyrite-driven autotrophic denitrification.

“…Anammox bacteria are globally significant contributors to the nitrogen cycle, as they release nitrogen to the atmosphere from freshwater lakes, marine sediments, and the marine water column, including the extremely cold arctic sediments (Vipindas et al, 2020). Laboratory cultivations have suggested the most significant contributions in temperate continental shelf locations (24% and 67% of total N 2 production) (Dalsgaard and Thamdrup, 2002).…”
