Abstract: A composition for destroying microorganisms is used for destroying microflora (bacteria, protozoan fungi, etc.) in a sessile state (hereinafter, a biofilm). The composition can find its application in medicine, industry, agriculture and various technical fields for destroying biological films comprised of complex bacterial communities in an extracellular polymeric substance (an exopolymeric matrix), which form on different types of surfaces: biological, industrial, etc. The composition is pre-prepared by dissolving an oxidant and a buffer compound in a solvent. Once the composition has been prepared, it is applied to a biofilm on the surface of an object.

Abstract: The invention relates to the field of microflora destruction technologies (bacteria, protozoan fungi, etc.), namely microorganisms in sessile state (hereinafter—biofilm), and can be used in medicine, industry, agriculture and various fields of technology for the destruction of biological films which are highly organized communities of bacteria in the extracellular polymeric substance (hereinafter referred to as the exopolymer matrix) formed on surfaces of different origin (biological, industrial, etc.). Pre-prepare the composition for the destruction of microorganisms in sessile state, for which dissolve the oxidizing agent and the substance that blocks the OH-group, in a solvent. An aqueous solution of sodium peroxodisulfate at a concentration of 10.00 wt. % And sodium hydroxide at a concentration of 15.00 wt. % Is used as components from which the composition is prepared for the destruction of microorganisms in the sessile state. Since the pH of the composition is greater than 10.
