Nitrogen removal by heterotrophic nitrification-aerobic denitrification bacteria: A review

Desalination and Water Treatment, Год журнала: 2024, Номер 317, С. 100227 - 100227

Опубликована: Янв. 1, 2024

The rising urbanization and industrialization are increasing nitrogen pollution in water wastewaters, calling for advanced remediation treatments. Traditional biological treatments limited area efficiency. Therefore, heterotrophic nitrification-aerobic denitrification (HN-AD) a single reactor has drawn significant attention shown higher Here we review HN-AD bacteria with focus on bacterial species, metabolism, factors influencing denitrification. Nitrogen metabolism pathway includes nitrate-nitrite reduction denitrification, hydroxylamine assimilatory Factors comprise carbon source, C/N, temperature, pH, DO so on. Compared to published literature reviews HN-AD, our manuscript comprehensively summary the latest research its remove mechanisms related enzymes first time.

Nitrogen removal in freshwater sediments of riparian zone: N-loss pathways and environmental controls

Frontiers in Microbiology, Год журнала: 2023, Номер 14

The riparian zone is an important location of nitrogen removal in the terrestrial and aquatic ecosystems. Many studies have focused on efficiency one or two processes zone, less attention has been paid to interaction different transformation impact situ environmental conditions. molecular biotechnology, microcosm culture experiments 15N stable isotope tracing techniques were used this research at Weinan section Wei River, reveal mechanism with multi-layer lithologic structure. results showed that rate was 4.14-35.19 μmol·N·kg-1·h-1. Denitrification, dissimilatory reduction ammonium (DNRA) anaerobic oxidation (anammox) jointly achieved natural attenuation process denitrification dominant (accounting for 59.6%). High dissolved organic nitrate ratio (DOC:NO3-) would promote denitrification, but when NO3- content than 0.06 mg/kg, DNRA occur preference denitrification. Furthermore, abundances functional genes (norB, nirS, nrfA) anammox bacterial 16S rRNA gene similar distribution patterns corresponding rates. Sedimentary NOX-, Fe(II), carbon (DOC) microbial abundance main factors affecting zone. Fe (II) promoted through dependent ferrous under mediation, DOC promotes enhancing effect. study can be management prevention control global pollution.
