Abstract
When virulent cells of Agrobacterium tumefaciens strain B6 were exposed to low-level microwave radiation at a frequency of 10,000 MHz and an intensity of 0.58 mW/cm2 for 30 to 120 min, a 30 to 60% decrease in their ability to produce tumors on potato and turnip disks was observed. This microwave exposure did not affect the viability of these bacteria or their ability to attach to a tumor-binding site nor did it induce thermal shock. This loss of virulence was reversible within 12 h.
摘要
当根癌土壤杆菌B6菌株的毒性细胞暴露于频率为10000兆赫、强度为0.58毫瓦/平方厘米的低水平微波辐射下30至120分钟时，观察到它们在马铃薯和芜菁圆盘上产生肿瘤的能力下降了30%至60%。这种微波照射不影响这些细菌的活力或它们附着于肿瘤结合位点的能力，也不会引起热休克。这种毒力丧失在12小时内是可逆的。
