Enhanced nitrogen removal and sludge characteristic in aerobic SBR by simultaneous nitrification and denitrification bacteria

Journal of Environmental Engineering and Landscape Management
Four efficient heterotrophic nitrification and aerobic denitrification (HN-AD) strains were applied in sequencing batch reactors (SBRs) via two bioaugmentation strategies to enhance the nitrogen removal and sludge characteristic.

Implementing potential climate‐smart practices through diverse partnerships

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1584-1598, September 2026.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Nitrogen‐Starved Wheat: A Multi‐Omics Perspective From Epigenome Regulation to Grain Quality

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
This review establishes epigenetic regulation, specifically H3K27ac and H3K27me3 dynamics at nitrogen transporter, assimilation, and storage protein loci, as a principal determinant of cultivar‐specific nitrogen use efficiency in hexaploid wheat, independent of DNA sequence variation, and identifies the rhizosphere microbiome as an integral but ...

Compartment‐Specific Functional and Taxonomic Responses of Plant Growth‐Promoting Microbiomes Following Oxytetracycline Trunk Injection in Citrus

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is the most destructive disease affecting citrus production worldwide. Trunk injection of oxytetracycline (OTC) is increasingly used to suppress the pathogen and improve tree performance, yet its ecological consequences for plant‐associated microbiomes remain poorly understood ...

Long-Term Nitrogen Removal Performance and Microbial Analysis in a SNAD-Based MBBR at Room Temperature

Molecules
In recent years, the simultaneous partial nitrification, anammox, and denitrification (SNAD) process has attracted considerable attention due to its advantages such as low energy consumption and low sludge production.

Simultaneous removal of concentrated organics, nitrogen and phosphorus nutrients by an oxygen-limited membrane bioreactor.

PLoS ONE, 2018
Simultaneous removal of organics, nitrogen and phosphorus was achieved in a bench-scale oxygen-limited membrane bioreactor (OLMBR). Due to the limited dissolved oxygen (~ 0.2 mg/L equilibrium concentration) and the increased sludge concentration ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Species‐level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees

New Phytologist, Volume 251, Issue 6, Page 3221-3237, September 2026.
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to
