FIELD: chemistry.
SUBSTANCE: invention relates to bacterial stabilisation of aqueous compounds. The composition contains at least one mineral and at least one strain of bacteria which are resistant and/or tolerant to aldehyde-forming and/or aldehyde-containing biocides and/or decompose said biocides. The invention includes step (a) for adding one or more aldehyde-forming and/or aldehyde-containing biocides to an aqueous compound in such an amount that the total amount of aldehyde-forming and/or aldehyde-containing biocides in the aqueous compound ranges from 250 ppm to 5000 ppm in terms of water content of the compound; (b) adding at least one water-soluble lithium compound to the aqueous compound in such an amount that the total amount of solubilised lithium in the aqueous compound ranges from 1000 ppm to 3000 ppm in terms of the weight of water in the compound. At least one water-soluble lithium compound is a lithium polymeric salt - homopolymer and/or copolymer of acrylic acid. Steps (a) and (b) can be executed simultaneously or separately in any sequence.
EFFECT: invention increases stability of properties of aqueous compounds.
