title: [Possible ways to include human exometabolites in the turnover of biological life support system].
abstract: Purpose of the investigation was to study feasibility to include solid and liquid human discharges in the turnover of bioregenerative life support systems for physical/chemical and biological treatment. Human exometabolites were mineralized by way of wet process in hydrogen peroxide in alternating electromagnetic field. The resultant solutions were used to water plants cultivated on a soil-like substrate or haydite. Given that urea as a source of nitrogen for BLSS is undesirable, in one of the experiments mineralization was followed by enzymatic urea decomposition with soybean flour urease. The experiments showed no difference in the productivity of plants cultivated on a standard mineral medium and with the use of mineralized exometabolites.
