“…On the other hand, other autotrophic nitrogen removal technologies, such as the completely autotrophic nitrogen‐removal over nitrate or the deammonnification processes, are operated with certain aeration and therefore will support the growth of totally different bacterial communities than those from the MBR Anammox bioreactor. Other attempts for the identification of bacterial communities of Two‐Step Anammox bioreactors have been conducted by cloning and quantitative PCR techniques . Both studies showed a dominance of anammox bacteria and the presence of other minor species, such as Chloroflexi‐related strains or low abundance of AOB .…”

Autotrophic nitrogen removal technologies have proliferated through the last decade. Among these, a promising one is the membrane bioreactor (MBR) Anammox, which can achieve very high solids retention time and therefore sets a proper environment for the cultivation of anammox bacteria. In this sense, the MBR Anammox is an efficient technology for the treatment of effluents with low organic carbon and high ammonium concentrations once it has been treated under partial nitrification systems. A lab-scale MBR Anammox bioreactor has been built at the Technological University of Delft, The Netherlands and has been proven for efficient nitrogen removal and efficient cultivation of anammox bacteria. In this study, next-generation sequencing techniques have been used for the investigation of the bacterial communities of this MBR Anammox for the first time ever. A strong domination of Candidatus Brocadia bacterium and also the presence of a myriad of other microorganisms that have adapted to this environment were detected, suggesting that the MBR Anammox bioreactor might have a more complex microbial ecosystem that it has been thought. Among these, nitrate-reducing heterotrophs and primary producers, among others, were identified. Definition of the ecological roles of the OTUs identified through metagenomic analysis was discussed.

“…As an autotrophic oxidation process, this process converts ammonium (NH 4 + ) to dinitrogen gas (N 2 ) using nitrite (NO 2 À ) as the electron acceptor, thus without requirement for aeration and addition of exogenous carbon sources compared to the conventional nitrification-denitrification process. Nowadays, the anammox process has been used to treat various wastewaters such as municipal wastewater (Leal et al, 2016), landfill leachate (Li et al, 2014;Wang et al, 2016), turtle breeding wastewater (Chen et al, 2013), swine wastewater (Waki et al, 2010), and high-salinity wastewater (Liu et al, 2014).…”

h i g h l i g h t sSimultaneous nitrogen and carbon removal was achieved in the SAD process. Contributions of anammox and denitrification to nitrogen removal were determined. Anammox and denitrifying bacteria dominated at low and high CODs, respectively. Brocadia sinica could grow with organic matter and tolerate high NO 3 À concentrations.a r t i c l e i n f o exhibited good diversity and abundance, but the diversity of anammox bacteria was less abundant. Brocadia sinica was able to grow in the presence of organic matter and tolerate high nitrite concentration. Anammox bacteria were predominant at low COD contents, while denitrifying bacteria dominated the microbial community at high COD contents. Anammox and denitrifying bacteria could coexist in one reactor to achieve the simultaneous carbon and nitrogen removal through the synergy of anammox and denitrification.

“…The total nitrogen removal efficiency (NRE) achieved in the reactor was 84% during the study period. NRE of SHARON-ANAMMOX LBFR was higher than that of the study by Li et al [9]. He reported partial nitritation-ANAMMOX processes in UASB at nitrogen loading of 1 to 2 kg N/m 3 /d with NRE of 62 ± 17%.…”

Landfill bioreactors (LFBR) are gaining significant attention as sustainable alternative for conventional landfilling. Nitrogen management is an important issue in landfill bioreactors. The present study is to establish the combined SHARON (single reactor system for high activity ammonia removal over nitrite) and ANAMMOX (anaerobic ammonium oxidation) processes in landfill bioreactors for in situ nitrogen management. Laboratory scale landfill bioreactors (43 L volume capacity) as SHARON-ANAMMOX LFBR were loaded with mined municipal solid waste operated for 147 days at a nitrogen loading rate of 1.2 kg N/m 3 /d. The results showed a nitrogen removal efficiency of 84% with maximum partial nitritation efficiency of 56% and specific ANAMMOX activity of 0.7 mg Amm-N/mg MLVSS/d was achieved in the LFBR. Nitrogen transformations, biomass development and, hydrazine and hydroxylamine formation authenticated the aerobic ammonium oxidising bacteria (AOB) and anaerobic ammonium oxidising bacteria (AnAOB/ANAMMOX) activities responsible for combined SHARON-ANAMMOX processes in LFBR. 99% of the biogas in LFBR as N 2 the end product confirmed the combined SHARON-ANAMMOX processes. The study successfully demonstrated the combined SHARON-ANAMMOX processes for in situ nitrogen management in landfill bioreactors with shorter start-up time and stable operation.
