Magnetic genes: Studying the genetics of biomineralization in magnetotactic bacteria. [PDF]
, 2020 Many species of bacteria can manufacture materials on a finer scale than those that are synthetically made. These products are often produced within intracellular compartments that bear many hallmarks of eukaryotic organelles.

Long-term observation of Magnetospirillum gryphiswaldense in a microfluidic channel [PDF]
Archives of Microbiology, 2019 We controlled and observed individual magnetotactic bacteria (Magnetospirillum gryphiswaldense) inside a 5 m high microfluidic channel for over four hours. After a period of constant velocity, the duration of which varied between bacteria, all observed bacteria showed a gradual decrease in their velocity of about 25 nm/s$^2$.

Formation of Core-Shell Nanoparticles Composed of Magnetite and Samarium Oxide in Magnetospirillum magneticum Strain RSS-1. [PDF]
PLoS ONE, 2017 Magnetotactic bacteria (MTB) synthesize magnetosomes composed of membrane-enveloped magnetite (Fe3O4) or greigite (Fe3S4) particles in the cells. Recently, several studies have shown some possibilities of controlling the biomineralization process and ...
