METHOD OF DETERMINING MICROBIAL-PLANT INTERACTION IN THE PROCESS OF DEVELOPMENT OF MICROORGANISMS BY MEASURING HEAT RELEASE FROM IT AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G01N25/20 

FIELD: biotechnology, experimental veterinary medicine, medicine and pharmacology.

SUBSTANCE: invention relates to a method and device for determining microbial-plant interaction. The method of determining the microbial-plant interaction in the process of development of microorganisms by measuring the heat release from it includes the following stages: a plant test sample is placed in the measuring cell; placing the test microbial sample in a passive state on the plant test sample or at a distance at which they can exert their influence on the development of the plant test sample when they enter the active state; create conditions for the development of plant test and microbial samples under study; monitoring the heat release of the plant test sample with the microbial sample under study at the first stage, when the microbial sample under study is still in a passive state in the lag phase, and at subsequent stages i, when the test sample enters the active log phase; determine the activity coefficient of the plant test sample from the following equation: G2=(dQ/dt)_i/(dQ/dt)_l-1, where dQ is the heat released; dt is a unit of time, while the activity coefficient at the first stage must coincide with the previously measured activity coefficient of the plant test sample under similar conditions without the studied microbial sample, calculated from the equation: G1=(dQ/dt)_l; the activity coefficients of the selected time intervals i are calculated, according to which the influence of the microbial sample under study on the plant test sample is judged.

EFFECT: ability to study the activity of interaction with plants mold fungi.
