Microorganisms dwelling in drinking water reclaimed from water containing water in an enclosed environment were identified. The microbial species in the water reclaimed from the condensate of hydrogen peroxide decomposition products and from the air humidity condensate showed specific features and differences when compared to those in natural water.

In an enclosed environment the species composition of microorganisms was quantified and metabolic processes in microbial cells isolated from the atmospheric condensate and reclaimed water were investigated. It was demonstrated that indicator microorganisms isolated from water and condensate samples (Alcaligenes faecalis, Citrobacter freundii, Aeromonas hydrophila, Acinetobacter-Moraxella) were specific and differed from indicator microorganisms typical of regular tap water.

The effect of different silver compounds (silver sulphate, silver nitrate, electrolytic ionic silver) on microorganisms in water reclaimed from the atmospheric condensate in an enclosed environment was investigated. The following microorganisms were examined: Alcaligenes faecalis, Citrobacter freundii. Aeromonas hydrophila, Staphylococcus epidermidis, etc. The ionic silver concentrations in solution varied from 0.1 to 10 mg/l. The efficiency of the silver compounds was found to depend on the microbial strain, ionic silver concentration in solution, and time of exposure. The microflora of the reclaimed water proved to be highly resistant to the preservatives which was strongly associated with the bacterial physical and chemical composition of the products preserved.
