METHOD TO DETECT TOXICITY OF MEDIUM BY EXTENT OF SUPPRESSION OF GROWTH OF MICROORGANISM TEST CULTURES Russian patent published in 2015 - IPC C12Q1/02 C12Q1/06 C12Q1/18 C12N1/36 C12R1/82 C12R1/685 C12R1/77 

FIELD: biotechnologies.

SUBSTANCE: method to detect toxicity of a medium includes determination of test culture growth parameters in control and experiment. As test cultures, they use micromycetes, and previously detect the parameter of degree of suppression of test cultures growth in experiment in respect to control, %, by formula: . They perform detection of integral parameter of medium toxicity in points by total quantity of points in all test cultures for the whole period of incubation, which is compared to five classes of medium hazard, conventionally set depending on point integral assessment of toxicity of tested medium from 0 to 100 points.

EFFECT: invention makes it possible to increase objectivity of assessment of medium toxicity for plants, animals and humans.
