“…Despite the fact that each discharge is unique and therefore the generalization of results is difficult or impossible, there is a prevailing consensus about the possible mechanisms of NTP affection of the treated object. For a brief overview of this topic, see [20]. In the active discharge area, many active particles are generated from the molecules or atoms of discharge atmosphere.…”

This paper presents the review of effects of nonthermal plasma (NTP) treatment on both the wheat grains and flour with potential to be applied in practice. The NTP can be used in wheat grain surface disinfection, grain germination and vitality improving, and wheat flour modification and disinfection. NTP causes effective decontamination from bacteria and fungi together with insect pests and causes minimal damage to wheat grains; it inactivates enzymes and enhances the grain shelf life; it enhances the germination and initial state of growth resulting in the increase of final yield. Moreover, the production of qualitatively better dough is also mentioned.

“…Any condition that can be improved by reducing the number of microorganisms on the skin is also a fair target. Plasma is known to disrupt biofilms, 72,103 which are shown to play a role in itch in patients with atopic dermatitis, for example 104 . While the first trial using CAP to reduce pruritus failed to show benefit, 105 further studies in this field are expected using different settings and different devices.…”

Cold atmospheric pressure plasma is physical plasma (essentially ionized gas) created at room temperature and atmospheric pressure, and it has complex effects on cells, tissues, and living organisms. These effects are studied extensively for medical and dermatological use. This article reviews current achievements and new trends in clinical dermatological cold plasma research, discusses the basics of plasma physics and plasma engineering, and describes the most important areas of laboratory plasma research to provide a wellrounded understanding of the nature, present applications, and future promise of this exciting, emerging technology.

“…Cold atmospheric plasma is an emerging antimicrobial strategy that could improve biofilm eradication (Julák et al, 2018;Gupta and Ayan, 2019). The word "plasma" was first used by Irving Langmuir in 1928 to describe quasineutral ionized or partially ionized gas generated by heating or through the application of a strong electromagnetic field (Šimončicová et al, 2019).…”

“…The normal ecological environment of microbial consortia that often coexist with its dwelling host may be easily disrupted by invading pathogens, which can outcompete healthy normal flora during their growth and transform the commensal consortia into pathogenic biofilms (Tytgat et al, 2019). Many pathogens often colonize joint replacements, heart valves, and metal or plastic implants to form mixed-species biofilms, which cause life-threatening diseases (Julák et al, 2018). Gomila et al (2019) conducted a multicenter retrospective cohort study on patients with complicated urinary tract infections from 20 hospitals in eight countries and found that 42.2% (341/807) of the patients have catheterassociated urinary tract infections.…”

Fighting Mixed-Species Microbial Biofilms With Cold Atmospheric Plasma

et al. 2020

Most biofilms in nature are formed by multiple microbial species, and such mixedspecies biofilms represent the actual lifestyles of microbes, including bacteria, fungi, viruses (phages), and/or protozoa. Microorganisms cooperate and compete in mixedspecies biofilms. Mixed-species biofilm formation and environmental resistance are major threats to water supply, food industry, and human health. The methods commonly used for microbial eradication, such as antibiotic or disinfectant treatments, are often ineffective for mixed-species biofilm consortia due to their physical matrix barrier and physiological interactions. For the last decade, an increasing number of investigations have been devoted to the usage of cold atmospheric plasma (CAP), which is produced by dielectric barrier discharges or plasma jets to prevent or eliminate microbial biofilms. Here, we summarized the production of CAP, the inactivation of microorganisms upon CAP treatment, and the microbial factors affecting the efficacy of CAP procedure. The applications of CAP as antibiotic alternative strategies for fighting mixed-species biofilms were also addressed.
