Key enzymes, functional genes, and metabolic pathways of the nitrogen removal-related microorganisms

Critical Reviews in Environmental Science and Technology, Journal Year: 2024, Volume and Issue: 54(23), P. 1672 - 1691

Published: May 16, 2024

Biological nitrogen removal is a classic technique for removing from wastewater that has been studied extensively and gives high rate, energy efficiency, relatively environmentally benign. Using biological processes to treat the diverse components of requires thorough understanding microorganisms pathways involved. However, information regarding participating in remains limited. This review presents current knowledge researches into these microorganisms, including ammonia oxidizing bacteria, archaea, complete oxidation nitrite-oxidizing anaerobic ammonium denitrifying heterotrophic nitrification-aerobic denitrification bacteria. The metabolic enzymatic reactions involved cycle abovementioned are demonstrated. key enzymes, functional genes, removal-related were discussed. Additionally, advantages different oxidation, denitrifying, HN-AD described. Finally, limitations strategies unraveling presented. aim improve our principle advanced allow possible improvements treatment be identified.

Comparative Metagenomic and Metatranscriptomic Analyses Reveal the Functional Species and Metabolic Characteristics of an Enriched Denitratation Community

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(22), P. 14312 - 14321

Nitrite supply for mainstream anammox via denitratation has attracted increasing attention. The functional species responsible and their metabolic characteristics were unravelled in this study. A highly stable community was enriched from activated sludge by combined control of C/N pH. accumulation nitrate removal efficiencies both higher than 80% during long-term operation (>100 d). genotypic complete denitrifier Thauera aminoaromatica MZ1T identified to be mainly acetate consumption, polyhydroxybutyrate (PHB) accumulation, reduction. presence restricted the transcription electron allocation downstream denitrifying enzymes due low expression transport modules (cytochrome bc1 cytochrome c). Metabolic reconstruction strain indicated that reducing power generated tricarboxylic acid (TCA) cycle provided PHB synthesis reduction exogenous feast phase. After depletion acetate, degraded then entered TCA cycle, providing This strategy with priority given carbon storage instead nitrite might favor survival oligotrophic weak alkaline habitats. These results updated our understanding causes underlying its physiological benefits.
