Magnetococcus marinus

Magnetococcus marinus is a species of Alphaproteobacteria that has the peculiar ability to form a structure called a magnetosome, a membrane-encased, single-magnetic-domain mineral crystal formed by biomineralisation, which allows the cells to orient along the Earth's geomagnetic field. The Magnetococcus marinus grows chemolithoautotrophically with thiosulfate and chemoorganoheterotrophically on acetate.

Magnetococcus marinus is a species of Alphaproteobacteria that has the peculiar ability to form a structure called a magnetosome, a membrane-encased, single-magnetic-domain mineral crystal formed by biomineralisation, which allows the cells to orient along the Earth's geomagnetic field.1 The Magnetococcus marinus grows chemolithoautotrophically with thiosulfate and chemoorganoheterotrophically on acetate.2

It is a basal group in the Alphaproteobacteria.
