It was shown that the static magnetic field (SMF) and electromagnetic field (EMF) caused inhibition of the cell division in Escherichia coli K-12 lon mutant. The low-frequency EMF 4 Hz led to the 20% survival, but EMF at 50 Hz increased the survival of cells up to 53%. After exposure to magnetic field cells lost capacity for division and grow as filaments, unable to form the colonies on the solid media.
结果表明，静磁场（SMF）和电磁场（EMF）会抑制大肠杆菌K-12 lon突变体中的细胞分裂。4Hz的低频电磁场导致20%的存活率，但50Hz的电磁场使细胞存活率提高到53%。暴露于磁场后，细胞失去分裂能力并长成丝状，无法在固体培养基上形成菌落。
