Ecological interactions and the underlying mechanism of anammox and denitrification across the anammox enrichment with eutrophic lake sediments

Microbiome, Journal Year: 2023, Volume and Issue: 11(1)

Published: April 20, 2023

Abstract Background Increasing attention has recently been devoted to the anaerobic ammonium oxidation (anammox) in eutrophic lakes due its potential key functions nitrogen (N) removal for eutrophication control. However, successful enrichment of anammox bacteria from lake sediments is still challenging, partly ecological interactions between and denitrifying across such with remain unclear. Results This study thus designed fill knowledge gaps using bioreactors enrich more than 365 days. We continuously monitored influent effluent water, measured denitrification efficiencies, quantified bacteria, as well related N cycling genes. found that maximum efficiencies NH 4 + NO 2 − reached up 85.92% 95.34%, respectively. Accordingly, diversity decreased significantly enrichment, relative dominant (e.g., Candidatus Jettenia) Thauera, Afipia ) shifted considerably. The cooperation tended increase microbial community stability, indicating a coupling bacteria. Moreover, nirS -type denitrifiers showed stronger nirK during enrichment. Functional potentials depicted by metagenome sequencing confirmed denitrification. Metagenome-assembled genomes-based model indicated most could provide various materials amino acid, cofactors, vitamin Cross-feeding highlights importance increasing lakes. Conclusions greatly expands our understanding mechanisms among sediments, which sheds new insights into controlling eutrophication.

Electricity-Driven Microbial Metabolism of Carbon and Nitrogen: A Waste-to-Resource Solution

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(11), P. 4379 - 4395

Published: March 6, 2023

Electricity-driven microbial metabolism relies on the extracellular electron transfer (EET) process between microbes and electrodes provides promise for resource recovery from wastewater industrial discharges. Over past decades, tremendous efforts have been dedicated to designing electrocatalysts microbes, as well hybrid systems push this approach toward adoption. This paper summarizes these advances in order facilitate a better understanding of electricity-driven sustainable waste-to-resource solution. Quantitative comparisons electrosynthesis abiotic are made, strategy electrocatalyst-assisted is critically discussed. Nitrogen processes including electrochemical N2 fixation, electrocatalytic reduction, dissimilatory nitrate reduction ammonium (DNRA), ammonia (Abio-NRA) systematically reviewed. Furthermore, synchronous carbon nitrogen using inorganic-biological discussed, advanced physicochemical, microbial, characterizations involved field. Finally, perspectives future trends presented. The valuable insights potential contribution valorization waste green society.
