The possibility of the activation of beneficial microorganisms using atmospheric plasma has rarely been examined. The application of plant growth-promoting bacteria (PGPB) as a microbial fertilizer to the field requires consistent efficiency. To overcome the limitations of PGPB as a microbial fertilizer, we investigated the potential of μ -dielectric barrier discharge plasma to increase the bacterial activity of a PGPB, Klebsiella pneumoniae , KW7-S06. Bacterial proliferation and vitality increased after plasma treatment. The infrared band of the observed Fourier transform infrared spectroscopy spectrum showed no change in the plasma-treated bacteria and untreated bacterial cell membranes. These results demonstrate that cells are not damaged by oxidative stress caused by plasma treatment. The density of bacteria adhering to the surface of rice seed inoculated with plasma-treated bacteria was higher than untreated bacteria. The germination rates of rice and barley see...

通过大气等离子体处理激活对植物有用的内生细菌

很少研究使用大气血浆激活有益微生物的可能性。将植物生长促进细菌（PGPB）作为微生物肥料在田间的应用需要始终如一的效率。为了克服PGPB作为微生物肥料的局限性，我们研究了μ介电屏障放电等离子体增加PGPB肺炎克雷伯菌，KW7-S06细菌活性的潜力。血浆处理后细菌增殖和活力增加。观察到的傅立叶变换红外光谱的红外波段显示，经等离子体处理的细菌和未经处理的细菌细胞膜没有变化。这些结果表明，细胞不会受到等离子体处理引起的氧化应激的损害。等离子体处理的细菌接种到水稻种子表面的细菌密度高于未处理的细菌。大米和大麦的发芽率见...
