Two main properties of atomic nuclei-mass and nuclear magnetic moments-are origin of many biological effects. Mass-dependent isotope effects have been studied for a long time. The effect of magnetic isotopes having a magnetic moment and spin was first shown in the early twenty-first century for the magnetic isotope magnesium Mg on enzymatic ATP synthesis. This stimulated the search for experimental evidence and theoretical justification of magnetic nuclei influence on biological processes. This review contains the results of scientific research on the magnesium magnetic isotope effects in microbiology. Microorganisms have been found to be sensitive to the presence of nuclear magnetic moment of magnesium isotope Mg compared with non-magnetic Mg isotopes.
原子核的两个主要特性——质量和核磁矩——是许多生物学效应的起源。长期以来，人们一直在研究与质量相关的同位素效应。21 世纪初，人们首次发现具有磁矩和自旋的磁性同位素对酶促 ATP 合成有影响，其中就包括带磁矩的镁同位素 Mg。这一发现激发了人们寻找更多关于磁性核对生物过程影响的实验证据和理论依据。本综述包含了微生物学中关于镁磁性同位素效应的科学研究结果。与非磁性的镁同位素相比，人们发现微生物对镁同位素 Mg 的核磁矩的存在很敏感。
