The paper describes the properties of a strain isolated from a natural population of soil microorganisms exposed to petrochemical production, capable of destroying fluorinated surfactants and some halogenated herbicides. In the model system, the growth dynamics of the DD4 bacterial strain was studied and it was shown that the culture actively accumulates biomass when using a fluorine-containing foaming agent such as a foaming agent and active substances of the herbicides Octapon, Chistalan, and Florax as a source of carbon and energy. Based on the data obtained, the DD4 bacterial strain can be used in remediation technologies for territories with a disturbed ecological status, formed when using fluoride-containing fire extinguishing agents and unregulated use of chemical plant protection products. According to the results of cultural-morphological, physiological-biochemical characteristics and the sequence of the 16S RNA DD4 gene, the strain was identified as a representative of the genus Pseudomonas.
