由植物病原体引起的植物疾病正深刻地影响着世界各地的农作物。在本研究中，利用大气压等离子体射流(APPJ)对番茄病原菌黄萎病菌进行了灭活。结果表明，弧菌的灭活效率与血浆浓度和处理时间有关。较高等离子体密度的APPJ在60 S作用时间内可完全杀灭抗性黄萎菌，由于等离子体产生的静电力，使黄萎菌外膜破裂，细胞质释放到周围的介质中。蛋白质和DNA分子都可以在血浆灭活过程中被破坏。同时，APPJ还为降低番茄种子腐烂率提供了一种新的途径。
Plant diseases resulting from plant pathogens are profoundly affecting crops worldwide. In this study, the tomato pathogen Cladosporium fulvum (C. fulvum) have been inactivated by using the atmospheric-pressure plasma jet (APPJ). The results show that the inactivation efficiencies of C. fulvum are dependent on the plasma density and treatment time. The APPJ with a relatively high plasma density can completely kill the resistant C. fulvum within the treatment time of 60 s. Due to plasma generating electrostatic force, the outer membrane of C. fulvum is disrupted and the cytoplasm is released to the surrounding medium. Both protein and DNA molecules can be destroyed during the plasma inactivation. Meanwhile, the APPJ can also provide a novel approach to decrease the rotting rates of C. fulvum-infected tomato seeds.
