Effect of Non-Equilibrium Plasma on Microorganisms Colonizing Diatomaceous Earth after the Beer Filtration Process

The present study evaluates the antimicrobial potential of non-equilibrium plasma against microorganisms isolated from diatomaceous earth, which is a waste product beer filtration process. For evaluation, earth an industrial brewery was treated with using glidearc reactor. temperature samples monitored. effect on morphology material investigated microscopically. Plasma can affect in various ways and change its physicochemical properties. Consequently, scope applications constantly expanding technologies to decontamination food industry, environmental protection medicine stimulates activities in, for example, agriculture medicine. At same time, microbiological analyzes were carried out determine presence selected groups before after treatment. revealed that porous structure not obstacle effective removal it plasma. A significant decrease amount both bacteria yeast relative control (non-plasma samples) observed increasing contact time numbers decreased by maximum 2.2 log10 CFU∙g−1 1.72 (30 min contact), respectively. obtained results are extremely promising encourage further, in-depth research optimize process microorganisms.
