Special Issue Information

Dear Colleagues,

Plasma Microbiology is a cutting-edge research field in plasma technology. Relevant areas of Plasma Microbiology involve plasma research related to microorganisms including bacteria, viruses, protozoa, fungi, and yeasts, as well as prions. In addition, Plasma Microbiology encompasses the application of plasma technology related to components of microorganisms, such as toxins and other biomolecules.

Plasma Microbiology covers a wide range of microbiology-related fields including medicine, agriculture, dentistry, and environmental science. Common topics shared among these different fields include the emergence of antibiotic-resistant bacterial strains, health-related concerns associated with biocidal agents and control measures for microbes, which can involve the prevention or encouragement of their growth. Recent advances in plasma technology enable the adoption of novel and complementary antimicrobial and promicrobial approaches.

In the medical and dentistry sector, plasma is sometimes utilized as a method of disinfection/sterilization, but the resistance against plasma is dependent on the type of microorganism. Moreover, the therapeutic potential of plasma technology is now being realized. In the agricultural sector, plasma can be used to enhance food preservation and help maintain food safety and quality by inactivating harmful microbes and promoting the proliferation of beneficial microbes. Plasma-based technology can also be used in environmental science for the disinfection of water and exhaust gases. Although recent studies have revealed the potential of plasma technology in a wide range of applications, its mode of action remains largely unknown. Therefore, further studies are required to investigate the molecular mechanism of the interaction of plasma with different microbes in a variety of scenarios that can lead to the inactivation or promotion of growth.

I propose a Special Issue dedicated to the microbiological applications of plasma. Original articles and reviews investigating the molecular mechanisms of plasma technology on microbiological targets to better understand their interactions with plasma are welcome. In addition, microbiological studies using plasma treatment solutions such as plasma-activated water (PAW), plasma-activated medium (PAM), plasma-activated liquid (PAL), plasma-treated medium (PTM), and plasma-treated liquid (PTL) are also welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The kingdom of Fungi is rich in species that live in various environments and exhibit different lifestyles. Many are beneficial and indispensable for the environment and industries, but some can threaten plants, animals, and humans as pathogens. Various strategies have been applied to eliminate fungal pathogens by relying on chemical and nonchemical antifungal agents and tools. Nonthermal plasma (NTP) is a potential tool to inactivate pathogenic and food-contaminating fungi and genetically improve fungal strains used in industry as enzyme and metabolite producers. The NTP mode of action is due to many highly reactive species and their interactions with biological molecules. The interaction of the NTP with living cells is believed to be synergistic yet not well understood. This review aims to summarize the current NTP designs, applications, and challenges that involve fungi, as well as provide brief descriptions of underlying mechanisms employed by fungi in interactions with the NTP components Full article

Prions, which cause transmissible spongiform encephalopathies (TSEs), are a notorious group of infectious agents with possibly the highest resistance to complete inactivation. Although various gas plasma instruments have been developed, studies on prion inactivation using gas plasma instruments are limited. Among them, the hydrogen peroxide gas plasma instrument, STERRAD® (Advanced Sterilization Products; ASP, Johnson & Johnson, Irvine, CA, USA), is recommended for prion inactivation of heat-sensitive medical devices. However, STERRAD® is not a plasma sterilizer but a hydrogen peroxide gas sterilizer. In STERRAD®, plasma generated by radio frequency (RF) discharge removes excess hydrogen peroxide gas and does not contribute to sterilization. This is also supported by evidence that the instrument was not affected by the presence or absence of RF gas plasma. However, recent studies have shown that other gas plasma instruments derived from air, nitrogen, oxygen, Ar, and a mixture of gases using corona, dielectric barrier, microwave, and pulse discharges can inactivate scrapie prions. As inactivation studies on prions other than scrapie are limited, further accumulation of evidence on the effectiveness of gas plasma using human-derived prion samples is warranted for practical purposes.
