  Abstract Regeneration of ionite artificial soil (AS) in root modules (RM) of conveyor-type space greenhouses should be proceeded by removal of root residues without disruption of the AS capillary-porous structure. The proposed method consists of two stages of root residues destruction. On the first stage, AS treatment by 0.7% an alkali water solution with added 0.7% hydrogen peroxide over 3.5 hours in a thermal-insulation container at 95 +/- 4 degrees C reduces root residue mass up to 60%. Specific energy cost of SHF pulses to maintain the required temperature is 1 W x hr for cleaning 1 g and AS sterilization from saprotrophs. On the second stage, AS undergoes saturation with a liquid anaerobic medium for 7-day cultivation of thermophilic Clostridium thermocellum at 55 degrees C. Seven days of bio-engineering regeneration enables removal of 90% root biomass. Residual products of fermentation have a stimulating effect on seed germination and subsequent plant growth. Bio-engineering testing of regenerated AS with cultivation of leaf cabbage Brassica chinensis L. attested to suitability of the technology for extension of AS useful life.
