“…For the first method, we used the same technology for plant cultivation, human exometabolite mineralization and irrigation water desalinization as that described by Zolotukhin et al [11]. During the vegetation period, we introduced mineralized urine (corresponding to 250 ml of natural urine) according to Kudenko's method [12] in 2 l of irrigation water.…”

“…However, considerable progress has been made in overcoming the problems raised by the utilization of NaCl in low concentrations by crop plants representative of a BLSS phototrophic unit [6][7][8][9][10]. One of the possible ways of some elements drop-preventing harmful effect of NaCl on plants was experimentally tested and described by Zolotukhin et al [11]. The feasibility of using a single substrate for four wheat vegetations was shown in this work.…”

Bioregenerative life-support systems (BLSS) are studied for developing the technology for a future biological life-support system for long-term manned space missions. Ways to utilize human liquid and solid wastes to increase the closure degree of BLSS were investigated. First, urine and faeces underwent oxidation by Kudenko's physicochemical method. The products were then used for root nutrition of wheat grown by the soil-like substrate culture method. Two means of eliminating sodium chloride, introduced into the irrigation solution together with the products of urine oxidation, were investigated. The first was based on routine electrodialysis of irrigation water at the end of wheat vegetation. Dialysis eliminated about 50% of Na from the solution. This desalinization was performed for nine vegetations. The second method was new: after wheat cultivation, the irrigation solution and the solution obtained by washing the substrate containing mineral elements not absorbed by the plants were used to grow salt-tolerant Salicornia europaea L. plants (saltwort). The above-ground biomass of this plant can be used as a food, and roots can be added to the soil-like substrate. Four consecutive wheat and Salicornia vegetations were cultivated. As a result of this wheat and Salicornia cultivation process, the soil-like substrate salinization by NaCl were considerably decreased.

“…We are considering the method of human wastes recycling suggested in the given work as a possible alternative to biological oxidation when high rates of wastes processing are required for their further inclusion into the intersystem matter turnover. Researchers of the Institute of Biophysics SB RAS (Russia) developed a unique physicochemical method (Kudenko and Pavlenko, 1998;Kudenko et al, 2000) to mineralize human wastes using H 2 O 2 and thus produce nutrient solution for plants (Zolotukhin et al, 2005). This may provide a way to involve human wastes into the mass exchange in the system and close the material loops in the BLSS much more efficiently.…”

“…One of the key elements for BLSS are plants [3][4][5] , as they regenerate ambient air by photosynthesis, help water recovery by transpiration, supply fresh food or nutritional needs for crews and can be used for the recycling of wastes. A maximum of biological materials could be reused for plant cultivation after involving various effective waste processing techniques [6][7][8] .…”

The development of life support artificial environments for crews and plants for long duration space flights is a challenge today. The concept of bio-regenerative life support system (BLSS) imitates a simplified natural environment. Experimental or theoretical modeling of BLSS requires a thorough understanding of natural activities from micro to macro scales, like with plant culture for food production, or CO 2 /O 2 conversion … Moreover, life support in space relies on both the amount of food and atmospheric O 2 produced by plants in a confined space. It is well known that, the enhancement of the gas exchange with leaves and the growth of plants are dependent on the organoleptic and the surrounding thermo-physical factors. Insufficient air movement around plants and/or condensation on plant leaves generally limit their growth by decreasing photosynthetic and transpiration rates. Thus, the optimization of a BLSS will require controlling the airflow and coupled gas/liquid transfer at the plant surfaces. Hence, we have developed an experimental setup at 1-g to study the hydrodynamics and the condensation mass flux on specific geometries in controlled environmental conditions. An air-conditioned closed circuit wind tunnel was used to generate a flow of controlled temperature, hygrometry and hydrodynamics. Condensation of humid air on a small size horizontal flat plate was investigated. The temperature of the active surface is controlled and maintained below the dewpoint to induce condensation. The experiments were performed at ambient temperature, with a relative humidity between 35-70% and for a velocity range of 1.0-3.0 m.s -1 . The results lead to the evaluation of the local mass transfer coefficients in various conditions. The goal of this study is to develop a theoretical model to predict condensation mass flux at interfaces to be used in a CFD approach related to a closed environment for space applications: planetary flights, lunar-Mars bases.
