Abstract
The results of experiments on application of a newly developed facility for oxidation of volatile organic compounds on a platinum catalyst are presented. The feasibility of using this method in artificial ecosystems as a whole and in mass exchange of closed biological-technical life support systems in particular is shown. The possibility of deep purification of gas emitted from the reactor of physical-chemical processing of organic wastes is demonstrated. Wheat growing experiment on using the facility for oxidation of volatile organic compounds in a sealed chamber was performed. No adverse effect of probable toxic oxidation products on wheat plants during a 4-day experiment was determined.

Funding
Works on manufacturing the facility for deep catalytic gas purification and its testing with the wet combustion reactor were performed with the support of the Russian Science Foundation (project no. 14-14-00599P) at the Institute of Biophysics, Siberian Branch, Russian Academy of Sciences. The experiment with wheat plants and the analysis of the pulse-modulated chlorophyll fluorescence was performed under the state assignment (no. VI.56.1.4) at the Institute of Biophysics, Siberian Branch, Russian Academy of Sciences.
