Abstract

The viability of the microbes Saccharomyces cerevisiae, Bacillus circulans, Escherichia coli, Micrococcus luteus, Pseudomonas fluorescens, Salmonella enteritidis, Serratia marcescens, and Staphylococcus aureus was tested under static magnetic field exposure up to 24 h in either a homogeneous (159.2 +/- 13.4 mT) or three types of inhomogeneous static magnetic fields: (i) peak-to-peak magnetic flux density 476.7 +/- 0.1 mT with a lateral magnetic flux density gradient of 47.7 T/m, (ii) 12.0 +/- 0.1 mT with 1.2 T/m, or (iii) 2.8 +/- 0.1 mT with 0.3 T/m. Even the longest period of exposure failed to produce any effect in the growth of bacteriae that could be correlated with static magnetic field exposure.

摘要

在均匀（159.2±13.4 mT）或三种非均匀静磁场中，对酿酒酵母、环状芽孢杆菌、大肠杆菌、藤黄微球菌、荧光假单胞菌、肠炎沙门氏菌、粘质沙雷氏菌和金黄色葡萄球菌等微生物进行长达24小时的静磁场暴露，测试其活力：（i）峰峰值磁通密度476.7±0.1 mT，横向磁通密度梯度为47.7 T/m；（ii）12.0±0.1 mT，梯度为1.2 T/m；或（iii）2.8±0.1 mT，梯度为0.3 T/m。即使最长时间的暴露也未能对与静磁场暴露相关的细菌生长产生任何影响。
