The combined effect of the zinc magnetic isotope Zn and weak magnetic field 25-35 mT causes a 2-4-fold increase in the colony-forming ability of bacteria E. coli in comparison with the nonmagnetic isotopes Zn. The effects of magnetic field in the range of 2.2-8 mT were detected for all bacteria regardless of the zinc-isotope enrichment of the media. This indicates the sensitivity of intracellular processes to weak magnetic fields. An increase in the ATP concentration in E. coli cells was only detected for the bacteria grown on the medium with the magnetic zinc isotope in the range of 2.2-4.2 mT. The obtained data confirm the existence of stages of intracellular enzymatic processes that are sensitive to magnetic fields and magnetic moments of atomic nuclei.
锌的磁性同位素Zn与25 - 35 mT的弱磁场共同作用，相较于非磁性同位素Zn，可使大肠杆菌的集落形成能力提高2至4倍。无论培养基中锌同位素的富集情况如何，在2.2 - 8 mT范围内的磁场对所有细菌均有影响。这表明细胞内过程对弱磁场敏感。仅在2.2 - 4.2 mT范围内，以磁性锌同位素为培养基生长的大肠杆菌细胞中检测到ATP浓度增加。所得数据证实存在对磁场和原子核磁矩敏感的细胞内酶促过程阶段。
