Magnetosome gene cluster containing bacteria in oxygen-stratified freshwater ecosystems of northern landscapes

Communications Earth & Environment
Magnetotactic bacteria (MTB) are capable of magnetic navigation (magnetotaxis) through the intracellular biomineralization of membrane-bound magnetic nanoparticles, known as magnetosomes, which are regulated by magnetosome gene clusters (MGCs).

Diversity and Dynamics of Microbial Community Structure in Different Mangrove, Marine and Freshwater Sediments During Anaerobic Debromination of PBDEs

Frontiers in Microbiology, 2018
Little is known about the diversity and succession of indigenous microbial community during debromination of polybrominated diphenyl ethers (PBDEs). This study examined the diversity and dynamics of microbial community structure in eight saline (mangrove

High diversity of anaerobic alkane-degrading microbial communities in marine seep sediments based on (1-methylalkyl)succinate synthase genes

Frontiers in Microbiology, 2016
Alkanes comprise a substantial fraction of crude oil and are prevalent at marine seeps. These environments are typically anoxic and host diverse microbial communities that grow on alkanes.

Akkermansia muciniphila enhances chicken resistance to infectious bronchitis virus by boosting GABA synthesis and suppressing the NF‐κB inflammatory pathway

iMetaOmics, Volume 3, Issue 1, March 2026.
Infectious bronchitis virus (IBV) represents a major threat to poultry production, with current control strategies offering limited protection. In this study, we demonstrate gut microbiome is a critical determinant of IBV resistance using fecal microbiota transplantation.

An integrated metagenomic and metabolite profiling study of hydrocarbon biodegradation and corrosion in navy ships

npj Materials Degradation, 2021
Naval vessels regularly mix fuel and seawater as ballast, a practice that might exacerbate fuel biodegradation and metal biocorrosion. To investigate, a metagenomic characterization and metabolite profiling of ballast from U.S.

Environmental and Spatial Factors Shaping Bacterial Communities in Eelgrass Sediments Along the Japanese Coast

Marine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT Zostera marina, commonly referred to as eelgrass, is a marine flowering plant frequently growing in some water‐saturated sediments along the coastal regions of Japan. We examined the bacterial communities in the sediment of three eelgrass areas to compare the bacterial composition of vegetated sediments (eelgrass sediments) with that of nearby

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Phylogenetic Profile of Copper Homeostasis in Deltaproteobacteria

, 2013
Copper homeostasis is achieved in bacteria through a combination of copper chaperones and transporting and chelating proteins. Bioinformatic analyses were used to identify which of these proteins are present in Deltaproteobacteria.

Pathways of carbon and energy metabolism of the epibiotic community associated with the deep-sea hydrothermal vent shrimp Rimicaris exoculata.

PLoS ONE, 2011
BackgroundThe shrimp Rimicaris exoculata dominates the faunal biomass at many deep-sea hydrothermal vent sites at the Mid-Atlantic Ridge. In its enlarged gill chamber it harbors a specialized epibiotic bacterial community for which a nutritional role has
