The high frequency electromagnetic (EM) waves have been proven as potent environmental polluters. The radio towers are considerably increasing to cater to the growing telecommunication requirements. The presented research focuses on the investigation of EM waves on antimicrobial potential of pharmaceutically important medicinal plants viz. Tulsi ( L.) and Brahmi (). The similar work has not been reported till date at the best of our knowledge. The medicinal plants were exposed to EM waves of 900 MHz possessing a 1.9 mG magnetic field. Our former investigation on plant physiology gave deteriorative effects on selected plants physiology in terms of growth, chlorophyll content, protein and carbohydrate content. In the presented article, the antimicrobial activity of two plants was inspected through various bacterial and fungal species. In case of , investigations revealed raise in Zone of Inhibition (ZOI) for both the bacterial and fungal strains in the range of 50%, whereas for increase of 63.26% and 59.42% ZOI for bacterial and fungal strains were noted respectively upon 24 h of exposure. Minimum Inhibitory Concentration (MIC) also decreased for 24 and 48 h of exposure. The transient raise in antimicrobial activity indicated the induction of plant defense system which can be considered as positive influence of short term radiation on medicinal properties of plants. Both plants exhibited the highest antimicrobial potential for and showing a prominent decline after 72 h of exposure. A substantial decline in antimicrobial in MIC of reported was 211% against and 166% against upon 144 h of exposure compared to control plants. The antimicrobial potential of was also decreased upon radiation, which is having a 392% reduction against and a 225% reduction against upon 144 h of exposure. The noteworthy deteriorative effects of radio waves on antimicrobial potential have been observed for both the medicinal plants.

无线电波非电离辐射暴露对药用植物抗菌潜力的影响

高频电磁 (EM) 波已被证明是有效的环境污染源。为了满足不断增长的电信需求，无线电塔正在大幅增加。本研究重点研究电磁波对药用植物（即药用植物）抗菌潜力的研究。图尔西 (L.) 和婆罗米 (Brahmi)。据我们所知，迄今为止尚未有类似工作的报道。将药用植物暴露于具有 1.9 mG 磁场的 900 MHz 电磁波中。我们之前对植物生理学的研究对选定的植物生理学在生长、叶绿素含量、蛋白质和碳水化合物含量方面产生了恶化影响。在本文中，通过各种细菌和真菌物种检查了两种植物的抗菌活性。在 的情况下，调查显示细菌和真菌菌株的抑制区 (ZOI) 均增加了 50%，而细菌和真菌菌株的 ZOI 在 24 小时后分别增加了 63.26% 和 59.42%。接触。暴露 24 小时和 48 小时后，最低抑菌浓度 (MIC) 也有所下降。抗菌活性的短暂升高表明植物防御系统的诱导，这可以被认为是短期辐射对植物药用特性的积极影响。两种植物都表现出最高的抗菌潜力，并且在暴露 72 小时后表现出显着下降。据报道，与对照植物相比，暴露 144 小时后，抗​​菌药物 MIC 显着下降 211% 和 166%。辐射后的抗菌潜力也有所下降，暴露 144 小时后，抗​​菌潜力降低了 392%，降低了 225%。无线电波对这两种药用植物的抗菌潜力具有显着的恶化作用。
