title: Effects of a strong static magnetic field on bacterium Shewanella oneidensis: an assessment by using whole genome microarray.
abstract: The effect of a strong static 14.1 T magnetic field on log phase cells of bacterial strain Shewanella oneidensis MR-1 was evaluated by using whole genome microarray of this bacterium. Although differences were not observed between the treatment and control by measuring the optical density (OD), colony forming unit (CFU), as well as post-exposure growth of cells, transcriptional expression levels of 65 genes were altered according to our microarray data. Among these genes, 21 were upregulated while other 44 were downregulated, compared with control.
