Magnetotactic Aquaspirillum magnetotacticum, which synthesize magnetosomes consisting of magnetite(Fe_3O_4), was grown in the 5L fermentor. The optimum dissolved oxygen(DO) concentration was 2.5% of air saturation concentration for the steady to produce magnetite. By unsteady state operation changing from higher DO to lower DO, more magnetite was produced than steady state operation. The mono sugars were shown inhibitory effect on the cell growth and magnetite formation.
