We report the novel use of magnetic particles isolated from magnetotactic bacteria. Magnetotactic bacteria were collected from enriched sludge by use of a magnetic harvesting apparatus. Magnetic particles separated from magnetotactic bacteria were shown to be pure magnetite. Glucose oxidase and uricase were immobilized on magnetic particles. The activity of glucose oxidase immobilized on biogenic magnetites was 40 times that immobilized on artificial magnetites or Zn-ferrite particles. Both glucose oxidase and uricase coupled with biogenic magnetic particles retained their activities when they were reused 5 times.
