Nanomaterials and Nanofluids for Environmental Applications: A Comprehensive Review

Journal of Engineering, Volume 2026, Issue 1, 2026.
Rapid industrialization, urban expansion, and rising energy demand have intensified global environmental challenges, including pollution and resource depletion. Nanomaterials and nanofluids have emerged as promising solutions due to their unique physicochemical properties and tunable surface characteristics, which enhance contaminant removal, catalytic

Integrated Global and Local Field Sensing in Magnetospirillum Magnetotacticum [PDF]

Biophysical Journal, 2012
The ability for organisms to evolve specialized functions is often correlated to unique intracellular structures, non-obvious to typical biological systems. One example is the biosynthesis of magnetic particles. Biology has evolved important magnetic sensing structures in a range of organisms from radula teeth in the chiton, algae, honeybees homing ...

A Method for Producing Highly Pure Magnetosomes in Large Quantity for Medical Applications Using Magnetospirillum gryphiswaldense MSR-1 Magnetotactic Bacteria Amplified in Minimal Growth Media

Frontiers in Bioengineering and Biotechnology, 2020
We report the synthesis in large quantity of highly pure magnetosomes for medical applications. For that, magnetosomes are produced by MSR-1 Magnetospirillum gryphiswaldense magnetotactic bacteria using minimal growth media devoid of uncharacterized and ...

Genome Editing Method for the Anaerobic Magnetotactic Bacterium Desulfovibrio magneticus RS-1. [PDF]

, 2018
Magnetosomes are complex bacterial organelles that serve as model systems for studying bacterial cell biology, biomineralization, and global iron cycling. Magnetosome biogenesis is primarily studied in two closely related Alphaproteobacteria of the genus

Structure and evolution of the magnetochrome domains: no longer alone [PDF]

, 2014
Magnetotactic bacteria (MTB) can swim along Earth's magnetic field lines, thanks to the alignment of dedicated cytoplasmic organelles. These organelles, termed magnetosomes, are proteolipidic vesicles filled by a 35–120 nm crystal of either magnetite or ...

A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

Greigite magnetosome membrane ultrastructure in ‘Candidatus Magnetoglobus multicellularis’ [PDF]

, 2008
The ultrastructure of the greigite magnetosome membrane in the multicellular magnetotactic bacteria ‘Candidatus Magnetoglobus multicellularis’ was studied. Each cell contains 80 membrane-enclosed iron-sulfide magnetosomes.

Phenotypical and Genomic Characterization of the Mollusk Pathogen Francisella halioticida

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Phenotypic and genetic characterization of French isolates of Francisella halioticida and comparison with Canadian and Japanese strains. The study revealed similarities between FR22s and previous isolates but distinct differences with FR21. A major finding is the absence of the Francisella pathogenicity island in the less virulent isolate, FR22b ...

Crystal structure of the magnetobacterial protein MtxA C-terminal domain reveals a new sequence-structure relationship

Frontiers in Molecular Biosciences, 2015
Magnetotactic bacteria (MTB) are a diverse group of aquatic bacteria that have the magnetotaxis ability to align themselves along the geomagnetic field lines and to navigate to a microoxic zone at the bottom of chemically stratified natural water.

Synchrotron‐Based Nano‐X‐Ray Absorption Near‐Edge Structure Revealing Intracellular Heterogeneity of Iron Species in Magnetotactic Bacteria

Small Science, 2022
Magnetotactic bacteria (MTB) sequester iron from the environment to biomineralize magnetite or greigite nanoparticles in magnetosome organelles, though the necessity of intracellular iron storage for the formation process is still in question ...
