Schematic chemical route of magnetite biomineralization in MSR-1. Magnetosome biomineralization occurs through the following steps: Iron uptake (store as a phosphate-rich ferric hydroxide phase), dephosphorization, transformation of iron ion into magnetosome vesicle, formation of magnetosome intermediates that composed of various kinds of iron oxides and formation of mature magnetosomes composed of magnetite. Gray circles in the figure refer to magnetosome membrane
