PURPOSE:To separate magnetotactic bacteria in high efficiency, by using a channel to flow water containing magnetotactic bacteria and a recovery chamber separated from the channel with a porous separation membrane and passing water containing magnetotactic bacteria through the channel while applying magnetic field perpendicular to the membrane, thereby recovering the magnetotactic bacteria in the recovery chamber. CONSTITUTION:The apparatus for the titled process is provided with a channel to flow water containing bottom sediment and magnetotactic bacteria and with a magnetotactic bacteria-recovery chamber separated from said channel with a separation membrane having a pore diameter of about 1-10mum and made of a nonmetallic material such as filter paper, glass filter and ceramic filter or a non-magnetic metal such as aluminum. The water containing bottom sediment and magnetotactic bacteria is passed through said channel while applying a magnetic field perpendicular to said porous membrane using an electromagnet such as Helmholtz coil or solenoid or a permanent magnet made of ferrite, metal, etc. The magnetotactic bacteria can be separated in the recovery chamber. |
