摘要: To investigate the effects of pulsed magnetic field on magnetosome formation in Magnetospirillum magneticum AMB-1, cultures inoculated with either mangetic or non-magnetic pre-cultures were incubated under 1 mT field. Magnetism cells was measured by using spectrophotometer coupled applied fields and values described as Cmag. Magnetosome counted transmission electron microscopy observation. The results showed that did not affect cellular growth, but enhanced formation. might exceed chain magnetosomes change homogeneity particles. implied magnetite precipitation induced adjacent affected Moreover, up-regulated magA mamA expression cells, which account for increasing number exceeding cells.
