The purpose of this work is to expand the spectrum of express-sensory systems and determine the most effective biological testing elements for creating biosensors for determining the quality of natural and drinking water. Research methods - spectrophotometric method; titrimetric method, direct seeding methods and membrane filters, light microscopy method; Statistical processing of data was performed to establish the experimental error. Work results: it is established that S. ambiguum reacts by decreasing the lifespan for the presence of any dissolved in water toxicant. The combination of bioindication with the use of the simplest chemical kinetics provides opportunities for biotesting natural and process waters. An experimental setup has been created that includes all the elements of the biosensor system according to the scheme: trap-transmitter-receiver-interpretation. A colorimetric biosensor with microorganisms was developed to monitor and detect water toxicity using ferricyanide as a colorimetric indicator and Escherichia coli as a model bacterium. Area of application: environmental protection.
