摘　　要：目的研究低温等离子体激活过硫酸盐溶液对红色毛癣菌生物膜杀灭效果。方法采用低温大气压等离子体射流装置灭活红色毛癣菌生物膜。结果红色毛癣菌经96 h培养形成完整的生物膜。大气压低温等离子体射流处理5 min,可完全杀灭红色毛癣菌生物膜。生物膜加水更容易被杀灭,过硫酸钠溶液可以提高低温等离子体射流杀灭红色毛癣菌生物膜的效果。结论低温等离子体射流可以杀灭红色毛癣菌生物膜,过硫酸盐可有效提高等离子体灭活红色毛癣菌生物膜的效率。Objective To study the killing effect of low-temperature plasma-activated persulfate solution on Trichophyton rubrum( T. rubrum) biofilm. Methods Low-temperature atmospheric pressure plasma jet( APPJ) device was used to treat the T. rubrum biofilm. Results T. rubrum formed a complete biofilm after 96 h of culture. Low-temperature APPJ was used for 5 min,and T. rubrum biofilm could be completely killed. Adding water to the biofilm was benefit for killing effect,and the sodium persulfate solution could promote the effect of low-temperature APPJ to kill T. rubrum biofilm. Conclusion Low-temperature APPJ can kill T. rubrum biofilm,and the sodium persulfate solution can effectively improve the efficiency of plasma inactivation of T. rubrum biofilm.
