Special Issue Information

Dear Colleagues,

Plasma-based technology has emerged as an energy-efficient, and environmentally friendly alternative with significant applications in food and environmental sciences. In the food sector, non-thermal plasma technologies can be applied to extend shelflife, improve safety through microbial decontamination, and enhance overall food quality. In environmental applications, thermal and non-thermal plasma technologies are used for water and air purification, pollutant degradation, hazardous waste treatment, energy recovery from organic solid waste, and resource recovery. This Special Issue aims to gather original research articles, reviews, and case studies that present recent advances, challenges, and future perspectives of plasma-assisted processes. Special attention will be given to contributions addressing fundamental mechanisms, innovative applications, optimization strategies, process scale-up, and interdisciplinary approaches that integrate plasma technology in food and environmental fields.

We investigated the effects of atmospheric-pressure plasma treatment on the growth of Saccharomyces cerevisiae by directly comparing plasma exposure and plasma-activated medium (PAM) under strictly identical discharge conditions. An atmospheric-pressure plasma jet operated with argon (Ar) or nitrogen (N2) was used. Yeast growth was analyzed using a phase-resolved kinetic framework that separately evaluated early growth behavior and exponential growth rate based on optical density measurements. Growth curves were normalized to same-day untreated controls to minimize day-to-day variability. Under N2 plasma conditions, both direct exposure and PAM treatment resulted in limited changes in growth kinetics (μrel = 0.67–0.97; trel ≈ 1.02–1.09). In contrast, Ar plasma treatment produced clear mode-dependent effects. Direct exposure delayed growth initiation (trel = 1.00–1.40) with a moderate reduction in μrel (0.63–0.84). PAM treatment strongly suppressed μrel (0.19–0.50), whereas trel varied across conditions without systematic prolongation (0.59–1.09). These findings demonstrate that treatment mode strongly influences which growth phase is predominantly affected, highlighting the importance of phase-resolved kinetic analysis for distinguishing plasma-induced biological effects beyond conventional endpoint measurements.
