Microwave-Assisted Inactivation of Fomite-Microorganism Systems: Energy Phase-Space Projection

This paper describes the use of log-linear energy phase-space projections to analyze microwave-assisted inactivation bacteria and viruses under different fomite conditions within multimode microwave ovens. The ovens are operated at a cavity-magnetron frequency 2.45 ± 01 GHz. Porous fomites (moist face towels, cotton swabs, kitchen sponges, scrubbing pads, cigarette filters N95-like respirators); along with non-porous hard surface syringe studied. classed as dielectric; absorb varying degrees depending on their complex dielectric permittivity. Microorganism resilience stress (defined ≥4 log10 reduction in inactivation) when mapped using iso-volume trend-lines reveals persistence imparted by fomite, can be between thermal treatment increases from vegetative Gram-negative Gram-positive spores. Bacteriophage MS2 influenza have an intermediate dependency. It is shown that linear-scaled temperature against process time graphs differentiate non-thermal micro-wave-assisted microorganisms.
