Tested was an idea to eliminate six harmful admixtures reside in a surrogate of atmospheric condensate of closed habitats by a cultivated bacterial association. The purpose was to select members of the bacterial associations that would assimilate acetone, acetic acid, ethanol, ethyl acetate, methylamine and ammonia as free, so immobilized on insoluble cellular polyvinylformal. The resulted association of three bacterial species showed the ability to transform into end products a six-component surrogate of atmospheric condensate. Methylopila capsulata VKM V-1606 metabolized methylamine, Paracoccus denitrificans VKM V-1324--acetone. Pseudomonas esterophilus VKM V-1736 D was found to act as an ethyl acetate destructor decomposing the admixture to ethanol and acidic acid which were oxidized also by this species to carbon dioxide and water. Each of these bacterial strains in the test association metabolized ammonia as a source of nitric nutrition.
