Denitrification performance, kinetics, and microbial community of methanol‐driven heterotrophic denitrification processes for treating nitrate‐rich water in recirculating mariculture system

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Large‐scale application of methanol‐driven heterotrophic denitrification (MHD) biofilms to recirculating mariculture systems (RMSs) is constrained by the requirement of precise methanol dosage. The emergence of intelligent aquaculture offers an opportunity to address this challenge, necessitating a comprehensive understanding of the ...

Contrasting Roles of Archaeal Core Clusters in Soil Nitrification of Northeast China’s Black Soil Region

Agronomy
The black soil region of Northeast China is crucial for agricultural productivity. Ammonia-oxidizing archaea (AOA) are key indicators of soil nitrification in this region, yet it remains unclear whether this process is driven by the entire community or ...

Large-scale distribution and activity of prokaryotes in deep-sea surface sediments of the Mediterranean Sea and the adjacent Atlantic Ocean.

PLoS ONE, 2013
The deep-sea represents a substantial portion of the biosphere and has a major influence on carbon cycling and global biogeochemistry. Benthic deep-sea prokaryotes have crucial roles in this ecosystem, with their recycling of organic matter from the ...

Mesoscale eddies: Hotspots of prokaryotic activity and differential community structure in the ocean [PDF]

, 1993
14 pages, 9 figures, 2 tablesTo investigate the effects of mesoscale eddies on prokaryotic assemblage structure and activity, we sampled two cyclonic eddies (CEs) and two anticyclonic eddies (AEs) in the permanent eddy-field downstream the Canary Islands.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

A hotspot for cold crenarchaeota in the neuston of high mountain lakes

Environmental Microbiology, 2008
Summary We have surveyed the first 1 m of 10 oligotrophic high mountain lakes in the Central Pyrenees (Spain) for both abundance and predominant phylotypes richness of the archaeaplankton assemblage, using CARD‐FISH and 16S rRNA gene sequencing respectively.

Distribution of Crenarchaeota Representatives in Terrestrial Hot Springs of Russia and Iceland [PDF]

Applied and Environmental Microbiology, 2008
ABSTRACT Culture-independent (PCR with Crenarchaeota- specific primers and subsequent denaturing gradient gel electrophoresis) and culture-dependent approaches were used to study the diversity of Crenarchaeota in terrestrial hot springs of the Kamchatka Peninsula and the Lake Baikal

Environmental factors shaping the ecological niches of ammonia-oxidizing archaea [PDF]

, 2009
For more than 100 years it was believed that bacteria were the only group responsible for the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative ammonia monooxygenase subunit A (amoA) gene and able to oxidize ammonia was ...

Microbial and Edaphic Responses to Invasion by Ageratina adenophora: Implications for Ecosystem Management

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study investigates how the invasive plant Ageratina adenophora alters soil properties and microbial communities to facilitate its spread. The findings show that invasion is associated with reduced soil moisture, increased nitrogen levels, and significant shifts in microbial composition, suggesting feedback mechanisms that enhance its invasiveness.
