Drastic suppression of benthic nitrogen fixation by restructuring diazotrophic communities following tidal wetland conversion to aquaculture ponds

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Tidal wetland reclamation is a widespread anthropogenic disturbance that alters sediment biogeochemistry; however, its impacts on biological nitrogen fixation (BNF) and diazotrophic communities remain poorly understood. Here, we integrated 15N isotope labeling, metagenomic sequencing, and network analysis across a bare tidal flat (B), moderate‐

Identification of rhizobial strains nodulating Egyptian grain legumes [PDF]

, 2013
The presence of apothecia in mixed species (vegetatively reproducing lichens, occasionally producing ascomata) has been interpreted as a mechanism to increase genetic variability in mostly clonal populations. However, spore viability from these apothecia

The Coral Host Microbiome Modulates the Virulence of the Bacterial Pathogen Vibrio coralliilyticus

Environmental Microbiology, Volume 28, Issue 1, January 2026.
The coral microbiome has been shown to protect the host (bottom right panel), but dysbiosis can increase susceptibility to infection by the bacterial pathogen Vibrio coralliilyticus. Treatment of Montipora capitata coral with antibiotics induced dysbiosis, which increased infection rates of less pathogenic V. coralliilyticus strains.

Characterization of microbiota composition and presence of selected antibiotic resistance genes in carriage water of ornamental fish. [PDF]

PLoS ONE, 2014
International trade with ornamental fish is gradually recognized as an important source of a wide range of different antibiotic resistant bacteria. In this study we therefore characterized the prevalence of selected antibiotic resistance genes in the ...

Bacterial Communities Associated with Poa annua Roots in Central European (Poland) and Antarctic Settings (King George Island)

Microorganisms, 2021
Poa annua (annual bluegrass) is one of the most ubiquitous grass species in the world. In isolated regions of maritime Antarctica, it has become an invasive organism threatening native tundra communities.

Efficient but Elusive Rhizobia Fix Nitrogen in the Wild Legumes Bituminaria bituminosa and Coronilla Viminalis

Journal of Basic Microbiology, Volume 65, Issue 12, December 2025.
ABSTRACT In ecological restoration of degraded natural habitats, revegetation with wild native plants is a priority. Legumes play a key role in this process through nitrogen (N)‐fixing symbiosis with rhizobia, obtaining N for their growth and improving soil fertility, which benefits other nonleguminous plants in the environment. This study explores the
