Abstract Soil microorganisms often thrive as microcolonies or biofilms within pores of soil aggregates exposed to the atmosphere. However, previous studies on physiology ammonia-oxidizing (AOM), which play a critical role in nitrogen cycle, were primarily conducted using freely suspended AOM cells (planktonic cells) liquid media. In this study, we examined growth two representative archaea (AOA), Nitrososphaera viennensis EN76 and “ Nitrosotenuis chungbukensis ” MY2, an bacterium, Nitrosomonas europaea ATCC 19718 polycarbonate membrane filters floated media observe their adaptation air-exposed solid surfaces. Interestingly, ammonia oxidation activities N. MY2 significantly repressed floating compared Conversely, activity was comparable developed filters. Transcriptome analysis filter-grown revealed upregulation unique sets genes for cell wall extracellular polymeric substance biosynthesis, H 2 O -induced oxidative stress defense, oxidation, including monooxygenase subunit C ( amoC3 ) multicopper oxidases. These may pivotal adapting AOA Furthermore, filter technique resulted enrichment distinct communities dominated by Ca . Nitrosocosmicus” clade. Overall, study sheds light adaptive mechanisms governing

Regulating Denitrification in Constructed Wetlands: The Synergistic Role of Radial Oxygen Loss and Root Exudates

Water, Journal Year: 2024, Volume and Issue: 16(24), P. 3706 - 3706

Published: Dec. 22, 2024

Constructed wetland (CW) is a critical ecological engineering for wastewater treatment and improvement of water quality. Nitrogen (N) removal one the vital functions CWs during operation, N in mainly affected by aquatic plants denitrification carried out microbes. However, due to their low efficiency instability removal, further applications are limited. The review provides view two basic characteristics plants, radial oxygen loss (ROL) root exudates, coupled effect on processes CWs. First, role presented. individual roles ROL exudates regulating denitrification, as well interaction this process, have been discussed. Also, limitation conventional techniques reveal between plant microbes has highlighted. Further research coupling regulatory mechanisms may be conducted develop an optimal design improve biological removal. This offers new insights directions improving utilizing synergistic effects exudates.
