The magnetic nanoparticles were extracted from Leptospirillum ferriphilum,strain YSK,isolated from acid mine drainages by treatment with sodium dodecyl sulfate(SDS)and centrifugation through a sucrose density *** electron microscopy(TEM)indicates that the nanoparticles are approximately spherical with a mean diameter of 44 nm,and magnetite crystals in this size range are single magnetic ***-dispersive X-ray analysis shows that the nanoparticles primarily contain two kinds of elements,iron and *** it can be concluded that the magnetic particles are ***,it is thought that cellular magnetotaxis is a direct consequence of the cell possessing *** discovery of magnetosomes in strain YSK can provide the theoretical basis for screening efficient bioleaching bacteria which are specific to different magnetic minerals under an outer magnetic field.
