“…In its turn the influence of DDW on the molecular dynamics of DNA can be explained by several mechanisms. It is known, that decrease of deuterium concentration in functionally active regions of a DNA molecule may increase the rate of transcription and replication [98]. The latter effect can be caused by the influence of deuterium on the probability of occurrence of open states between complementary pairs of nitrogenous bases, which can significantly change the speed of reading genetic information.…”

“…The water vapors and collected water should be treated by methods as close to the natural treatment processes (electrostatic ionization, soil infiltration, percolation, etc.) as possible to provide its biological activity (Sinyak et al, 2003).…”

“…For example, the electrostatic treatment of water vapors can be accomplished by Chizhevsky air ionizers. The results of space technology studies demonstrating that a reduced concentration of deuterium in water can enhance the biological activity of water, which implies a higher rate of biomass growth and faster consumption of wastes, can also be utilized (19). If necessary, the collected water can be treated to a higher purity degree by the solar still integrated with the greenhouse (20).…”
