Bacterial species capable of performing both nitrification and denitrification in a single vessel under similar conditions have gained significance the wastewater treatment scenario considering their unique character above reactions heterotrophic aerobic respectively. Such novel strategy often referred to as simultaneous (SND) has tremendous potential dealing with various wastewaters having low C : N content, that process needs very little or no external carbon source oxygen supply thus adding its cost-effective environmentally friendly nature. Though like other micro-organisms, nitrifiers denitrifiers convert inorganic organic nitrogen-containing substances into harmless dinitrogen gas wastewater, ecophysiological role global nitrogen cycle is still not fully understood. Attempts highlight played by pollution environmental operating will help developing mechanistic understanding SND address issues faced traditional methods autotrophic nitrification-anaerobic denitrification.

Successive side-stream phosphorus recovery challenges the stable enhanced biological (P) removal process due to stripping of P from sludge. In this study, a novel anaerobic/oxic/anoxic simultaneous nitrification, denitrification, and integrating (AOA-SNDPRr) was proposed operated under ultralong sludge retention time (SRT, 120–140 d). Results showed that effective carbon, nitrogen, obtained. High contents within (15–30 mg P/g MLSS) were kept even after an 80 day continuous extraction, thus supporting considerable anaerobic concentrations (10–30 mg/L). Up 81.60% influent harvested, in situ reduction by 63.2% with low observed yield (Yobs) 0.015 g MLSS/g chemical oxygen demand 50% extraction ratio. Interestingly, long-time operation witnessed spontaneous granulation. Abundant extracellular polymeric substances (EPS), particularly viscous polysaccharides (PS), stimulated. A 16S rDNA sequence demonstrated overwhelmingly dominated Candidatus_Competibacter soared 20.18%–25.91% without deteriorating removal. Negligible impact on functional genes for poly-P/Gly synthesis decomposition found. Overall, AOA-SNDPRr long SRT proved be sustainable approach targeting three goals reliable wastewater treatment, efficient recovery, dramatic minimization.

Plant invasions play a significant role in global environmental change. Traditionally, it was believed that invasive plants absorb and utilize nitrogen (N) more efficiently than native by adjusting their preferred N forms accordance with the dominant present soil. More recently, are now understood to optimize acquisition directly mediating soil transformations. This review highlights how exotic species influencing dynamics based on forms, various mechanisms, including biological nitrification inhibitor (BNI) release, pH alterations, changes nutrient stoichiometry (carbon ratio), regulate of plants. Generally, accelerate gross transformations maintain high supply NH4+ NO3− nitrogen-rich ecosystems irrespective preference. However, they tend minimize losses enhance availability nitrogen-poor ecosystems, where, such situations, different preferences usually affect transformation processes. Therefore, comprehensive understanding requires situ data interactions between plant species’ preferential form uptake characteristics Understanding combination these processes is essential elucidate use efficiency (NUE) through denitrification, leaching, or runoff, which considered critical for success species. also some most recent discoveries responses amounts acquisition, emphasizing significance plant–soil potentially influence dynamics.
