METHOD OF PRODUCING BIORECEPTOR ELEMENT IN FORM OF BIOFILM BASED ON MICROORGANISMS FOR ELECTRODE OF BIOSENSOR ANALYTICAL DEVICE AND BIOSENSOR ANALYTICAL DEVICE FOR DETECTING LEVEL OF CONTAMINATION OF WATER WITH BIODEGRADABLE ORGANIC COMPOUNDS Russian patent published in 2025 - IPC C12Q1/02 C12M1/40 

FIELD: biotechnology.

SUBSTANCE: invention relates to biotechnology, in particular to a biosensor analytical device for detecting the level of water contamination with biodegradable organic compounds. Said device comprises measuring cell (4) with a buffer solution, magnetic stirrer (5), silver chloride electrode (3) and a biosensor system, including graphite electrode (1) containing an electron transport mediator and bioreceptor element (2) in the form of a biofilm based on microorganisms, characterized by that used microorganisms are bacteria Pseudomonas veronii VKM B-3835. Invention also relates to a bioreceptor element for an electrode of a biosensor analytical device for detecting a level of contamination of water with biodegradable organic compounds in the form of a biofilm based on microorganisms, characterized by that the microorganisms used are Pseudomonas veronii VKM B-3835 bacteria, as well as a method for production thereof.

EFFECT: present invention widens the range of determined values of biochemical oxygen consumption (BOC) and sensitivity to a wide range of biodegradable organic compounds.
