摘要：

The phenomenon called growth advantage in stationary phase (GASP) originally discovered by Kelter et al. was confirmed using two bacterial strains, Escherichia coli ZK126Nal(r) and ZK126Sm(r), under the geomagnetic field. However, when the same experiment was conducted in an inhomogeneous high magnetic field of 5.1-6.1 T, almost no death of ZK126Sm(r) was observed and the: GASP phenomenon disappeared. When the same experiment was conducted in a homogeneous magnetic field of 7 T, the GASP was significantly delayed due to the much slower death rate of ZK126Sm(r) than that in the geomagnetic field. These data are consistent with our previous finding that a high magnetic field reduces the death rate of bacteria and enhances their survivability in a stationary phase.
