Plant–microbe interactions drive the rhizosphere microbial assembly and nitrogen cycling in a subtropical forest

Functional Ecology, Volume 39, Issue 5, Page 1274-1287, May 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between plants and soil microorganisms in the rhizosphere are vital for maintaining the nutrient cycle and stability of terrestrial ecosystems. Nitrogen, closely related to carbon (C) cycling and ecosystem productivity, undergoes transformation by soil ...

Probe Capture Enrichment Sequencing of amoA Genes Improves the Detection of Diverse Ammonia‐Oxidising Archaeal and Bacterial Populations

Molecular Ecology Resources, Volume 25, Issue 3, April 2025.
ABSTRACT The ammonia monooxygenase subunit A (amoA) gene has been used to investigate the phylogenetic diversity, spatial distribution and activity of ammonia‐oxidising archaeal (AOA) and bacterial (AOB), which contribute significantly to the nitrogen cycle in various ecosystems. Amplicon sequencing of amoA is a widely used method; however, it produces

Ammonium oxidation by bacteria and archaea have functional implications for nitrification across a forested landscape

Ecosphere, Volume 15, Issue 12, December 2024.
Abstract Ammonia‐oxidizing archaea (AOA) and ammonia‐oxidizing bacteria (AOB) control nitrification in terrestrial systems. Soil pH and substrate availability (NH4+) can influence community composition, which may affect the contributions of these organisms to nitrification in forest soils. Using high‐throughput sequencing, we identified the amoA of AOA

Compound drought-heat legacies promote the contribution of comammox Nitrospira to N2O emissions: as evidenced from both acidic and alkaline soils

Geoderma
The responses of complete ammonia oxidization (comammox) to compound drought and heat and their contributions to post-drought nitrous oxide (N2O) emissions remain unclear.

Using off‐gas testing to map mixing gradients and audit blower capacity

Water Environment Research, Volume 96, Issue 11, November 2024.
The payback of partial or complete blower replacement may not be justified even in the event of excessive aeration, and sequencing of aeration system improvements including diffuser replacement, process controls, and blower modifications/improvements should be considered and evaluated together.

Stabilization of nitrite in the presence of the nitrification inhibitor allylthiourea (ATU) in freshwater nitrification rate measurements

Limnology and Oceanography: Methods, Volume 22, Issue 10, Page 752-758, October 2024.
Abstract Nitrification rate measurements provide critical information on the performance of an environmental process central to the N cycle and are best studied using isotope labeling techniques. However, combining the high sensitivity of isotope labeling techniques with selected inhibition of nitrifiers as a whole or of specific nitrifier guilds has ...

Metagenomics reveal the potential for geosmin and 2‐methylisoborneol production across multiple bacterial phyla in recirculating aquaculture systems

Environmental Microbiology, Volume 26, Issue 10, October 2024.
Metagenomics reveal potential geosmin and MIB producers in five bacterial phyla (Acidobacteriota, Actinobacteriota, Bacteroidota, Chloroflexota, and Myxococcota) in recirculating aquaculture system microbiomes, which expands the phylogenetic diversity of potential off‐flavour producers.

Component Microenvironments and System Biogeography Structure Microorganism Distributions in Recirculating Aquaculture and Aquaponic Systems [PDF]

, 2019
Flowthrough and pond aquaculture system microbiome management practices aim to mitigate fish disease and stress. However, the operational success of recirculating aquaculture systems (RAS) depends directly on system microbial community activities. In RAS,
