Abstract
Various bacteria, actinomycetes, fungi, and bacteriophages were exposed to microwaves of 2,450 +/- 20 MHz in the presence and in the absence of water. It was found that microorganisms were inactivated only when in the presence of water and that dry or lyophilized organisms were not affected even by extended exposures. The data presented here prove that microorganisms are killed by "thermal effect" only and that, most likely, there is no "nonthermal effect"; cell constituents other than water do not absorb sufficient energy to kill microbial cells.
摘要
将各种细菌、放线菌、真菌和噬菌体置于有水和无水的条件下，暴露于2450±20兆赫的微波中。结果发现，只有在有水的情况下微生物才会失活，而干燥或冻干的生物体即使长时间暴露也不受影响。此处给出的数据证明，微生物仅因“热效应”而被杀死，而且很可能不存在“非热效应”；除水以外的细胞成分无法吸收足够的能量来杀死微生物细胞。
