摘要: This study examined the microbicidal activity of ultraviolet (UV)-C185–256-nm irradiance (robot 1) and ozone generated at UV-C185-nm by low-pressure mercury vapor lamps 2) adapted to mobile robotic devices for surface decontamination, which was achieved in less than 1 h. Depending on their wall structure outer envelopes, many microorganisms display different levels resistance decontaminating agents. Thus, need novel disinfection approaches is further exacerbated increased prevalence multidrug-resistant bacteria, as well potential microorganisms, with ability cause disease outbreaks. To set up a rapid effective approach propagation prevention, we focused effects UV-C distinct microorganism survival ratio. A including Escherichia coli, Micrococcus luteus, Saccharomyces cerevisiae, Trichoderma harzianum, Bacillus subtilis, were used evaluate power plus generating robots. can be suited ad hoc tasks, easy operate, requires low maintenance, does not have storage dangerous chemicals, produce by-products that may affect human health environment. The cumulative irradiation technology developed (fluence accumulated values 2.28 3.62 mJ cm−2, robot 2, respectively), together production (with maximum peak 0.43 ppm) capable reaching shaded surfaces, analyzed current study, despite being designed reduce risk epidemic outbreaks real-life scenarios, represents versatile tool could employed air within circumstances are faced daily.
