Реферат: eng: The luminescent response of the enzymatic system of Armillaria borealis on the cold and hot extracts from cell-free culture liquids of Inonotus obliquus, Pholiota sp. and A. borealis was examined. The greatest influence on the light emission produced by the luminescent system of A. borealis was provided by the temperature at which the probes were prepared for assay. Boiling a culture liquid on water bath for a few minutes promoted a multifold increase in the luminescence. The results of luminescence assay suggest that the substance involved in the bioluminescent reaction in higher fungi is presented in culture liquids and mycelia in two forms. In one form, it is ready to interact with the enzymatic system and in the second form, it becomes accessible for the reaction after heat treatment. The pool of thermoactivated substance was found to be much large than the amount of the ready accessible one. We suggest that predecessors of hispidin, which is fungal luciferin precursor, are responsible for this phenomenon. They are not involved in bioluminescence at their original state and are converted into the substrate under the influence of high temperature. © 2019, © 2019 The Author(s).
