In addition to energy recovery, the anaerobic digestion of agro-industrial byproducts can also produce different high-value-added compounds. Two-stage and single-stage reactors were compared for microbial communities’ selection long-chain fatty acid (LCFA) accumulation investigate which genera are most linked production these The communities present in two reactors’ configuration steady state characterised by 16S rRNA amplicon sequencing, while LCFAs extracted quantified from digestate samples gas chromatography. results showed differentiation microbially dominant families setups: Defluviitaleaceae Clostridiaceae acidogenic methanogenic reactor two-stage reaction respectively, Dysgonomonadaceae set-up. LCFA was significantly detected only reactor, with palmitic (2764 mg/kg), linoleic (1795 mg/kg) stearic (1751 acids as abundant. dominance UCG 011, along low abundance oxidiser Syntrophomonas spp. could be such Therefore, shaped affected LCFAs, indicating that more effective than digestion.

This study investigates the potential of humic substances (HS) and graphene oxide (GO), as extracellular electron acceptors (EEA) for nitrification, aiming to explore alternatives sustain this process in wastewater treatment systems. Experimental results demonstrate conversion ammonium nitrate (up 87 % conversion) coupled reduction either HS or GO by anaerobic consortia. Electron balance confirmed contribution oxidation. Tracer analysis incubations performed with 15NH4+ demonstrated 15NO3- main product a minor fraction ending 29N2. Phylogenetic identified Firmicutes, Euryarchaeota, Chloroflexi microbial lineages potentially involved anoxic nitrification linked reduction. introduces new avenue research which carbon-based materials electron-accepting capacity may support oxidation ammonium, instance bioelectrochemical systems anodes could novel process.

Abstract Partial nitritation (PN) is a novel treatment for nitrogen removal using aerobic ammonium oxidation with reduced oxygen requirements compared to conventional nitrification. This study evaluated the performance of PN process and factors influencing from landfill leachate. During reactivation biomass, results showed 70% removal, but only 20% total removal. Further analysis that low nitrite accumulation high nitrate production promoted growth nitrite‐oxidizing bacteria (NOB). The activity after soaking cultivated biomass in synthetic water leachate was measured be 0.57, 0.1, 0.17, 0.25 g N•g VSS −1 •d wastewater wastewater, 12 h, 3 days, 7 respectively. found abundant ammonium‐oxidizing (AOB) NOBs soaked wastewater. However, AOB inhibited NOB making suitable PN. Practitioner Points longer leachate‐soaking period increases, which turn increases conversions during process. Ammonium‐oxidizing can acclimate substrate grow period. Nitrite‐oxidizing (NOB) were by substrate, beneficial accumulation. Anabolized DO convert rapidly, higher Hence, level has sufficiently prevent
