A novel role for Crp in controlling magnetosome biosynthesis in Magnetospirillum gryphiswaldense MSR-1. [PDF]

Sci Rep, 2016
AbstractMagnetotactic bacteria (MTB) are specialized microorganisms that synthesize intracellular magnetite particles called magnetosomes. Although many studies have focused on the mechanism of magnetosome synthesis, it remains unclear how these structures are formed. Recent reports have suggested that magnetosome formation is energy dependent.

Work Patterns of MamXY Proteins during Magnetosome Formation in Magnetospirillum gryphiswaldense MSR-1. [PDF]

Appl Environ Microbiol, 2019
mamXY operon genes play an essential role in magnetite biomineralization, participate in redox reactions, and control magnetosome shape and size. However, mechanisms whereby the four MamXY proteins function together in iron oxidoreduction and transport are poorly understood.

Collective Response and Navigation Dynamics of Magnetospirillum gryphiswaldense under Rotating Magnetic Fields. [PDF]

Small
The dynamics of Magnetospirillum gryphiswaldense under rotating magnetic fields are explored through the analysis of thousands of trajectories. The study reveals distinct navigation modes and transitions influenced by field strength and frequency. Directionality, alignment, and swimming behavior are examined to uncover how these microorganisms respond ...

Reevaluation of the Complete Genome Sequence of Magnetospirillum gryphiswaldense MSR-1 with Single-Molecule Real-Time Sequencing Data. [PDF]

Genome Announc, 2018
ABSTRACT Magnetospirillum gryphiswaldense is a key organism for understanding magnetosome formation and magnetotaxis. As earlier studies suggested a high genomic plasticity, we (re)sequenced the type strain MSR-1 and the laboratory strain R3/S1. Both sequences differ by only 11 point mutations, but organization of the

Characterization and Phylogenetic Analysis of a Novel Uncultivated Magnetotactic Coccus Harbouring Multi-Chain Magnetosomes. [PDF]

Environ Microbiol Rep
A novel marine magnetotactic coccus, strain HHB‐1, was isolated from intertidal sediments in Houhai Bay, China. HHB‐1 cells are large coccoid–ovoid bacteria that contain multiple chains of prismatic magnetite magnetosomes and conspicuous Ca/Mg‐rich polyphosphate granules.

Electroactivity of the magnetotactic bacteria Magnetospirillum magneticum AMB-1 and Magnetospirillum gryphiswaldense MSR-1

Frontiers of Environmental Science & Engineering, 2023
Abstract Magnetotactic bacteria reside in sediments and stratified water columns. They are named after their ability to synthesize internal magnetic particles that allow them to align and swim along the Earth’s magnetic field lines. Here, we show that two magnetotactic species, Magnetospirillum magneticum strain AMB-1 and Magnetospirillum ...

Effects of Environmental Conditions on High-Yield Magnetosome Production by Magnetospirillum gryphiswaldense MSR-1 [PDF]

Iran Biomed J, 2019
Magnetotactic bacteria are a heterogeneous group of Gram-negative prokaryote cells that produce linear chains of magnetic particles called magnetosomes, intracellular organelles composed of magnetic iron particles. Many important applications have been defined for magnetic nanoparticles in biotechnology, such as cell separation applications, as well as

The Disruption of an OxyR-Like Protein Impairs Intracellular Magnetite Biomineralization in Magnetospirillum gryphiswaldense MSR-1. [PDF]

Front Microbiol, 2017
Magnetotactic bacteria synthesize intracellular membrane-enveloped magnetite bodies known as magnetosomes which have been applied in biotechnology and medicine. A series of proteins involved in ferric ion transport and redox required for magnetite formation have been identified but the knowledge of magnetosome biomineralization remains very limited ...
