Control of bacterial growth and enzymatic activity by an applied magnetic field

磁场可以在生物系统中引起多种效应，包括DNA复制或转录水平的变化以及离子和蛋白质跨膜流动的改变。然而，磁场对生物体的影响仍然存在争议。在这项研究中，我们专注于由外加磁场（数百mT范围的磁通量密度）引起的环境微生物的生长变化。从土壤中分离出了一些对磁场敏感的微生物。为了揭示这些微生物的种类或菌株以及这些机制，我们研究了外加磁场引起的这些微生物代谢的变化

Magnetic fields may induce multiple effects in biological systems, including change in DNA replication or transcriptional levels and modifications of ion and protein flow across membranes. However, effects o f the magnetic field on organisms are still controversial. In this study, we focused on growth changes of environmental microbes caused by the applied magnetic field (hundreds of mT range of a magnetic flux density). Some microbes that should be susceptible to the applied magnetic field were i s o l a t e d from the soil. To reveal the species or strain of these microbes and these mechanisms, we investigated changes of these microbial metabolisms caused by the applied magnetic field
