Plasma-Chemical Method of Grain Fungal Contamination Control

Abstract

The experimental results on the effect of grain treatment with ozone-air mixture on the level of artificial grain contamination with micromycetes are presented. The contamination dynamics for 1000 kg of wheat grain contaminated with Penicillium nordicum and Aspergillus flavus and stored in the prototype grain storage unit in ozone environment for 6 months is shown. The study on the effect of ozone on the growth inhibition of Aspergillus flavus for maize grain and Penicillium verrucosum for wheat grain in a 100 dm3 silo is presented. The effect of ozone on the content of aflatoxins in maize grain additionally contaminated with Aspergillus flavus is studied. The efficiency of ozone technologies for large-scale grain storage, as well as for reducing fungal contamination and controlling mycotoxin content in food grains, is shown.

Study of the efficiency of ozone synthesis in a point‐to‐plain discharge in N2–O2 mixtures

“…The intensive development of low-temperature plasma technologies based on atmospheric discharges has been realized by its applications in wide areas such as water treatment, [1] bio-medicine, [2][3][4] air treatment and purification, [5,6] agriculture, [7,8] and ozone generation. [9,10] As a rule, the applied goal of discharge investigation is to improve the plasma-chemical reactors for more efficient generation of plasma products (irradiation, active agents such as ozone and others).…”

Studying the Influence of Plasma-Chemical and Ozone Treatment on Artificially Implemented Microflora in Model Aqueous Solutions

“…Ozone has a strong bactericidal, virucidal, sporicidal and fungicidal action [4,5]. In particular, the greatest sensitivity to ozone was observed in both indicator bacteria and pathogens.…”
