This communication aims to expose further the assertions made in microscopic theory of black hole (MTBH) to the physics of intermediate mass black holes (IMBHs). The MTBH explores the most important spontaneous breaking of gravitation gauge symmetry above nuclear density. One of the most remarkable drawback of this framework is the fact that instead of infinite collapse and central singularity, an inevitable end product of the evolution of massive object is the stable superdense proto-matter core (SPC), subject to certain rules. The physical entropy is assigned to SPC as a measure of the large number of thermodynamical real microstates of proto-matter, which is compatible with a concept of ergodicity. The SPCs could be observed only in presence of accreting matter. As a corollary, this allows to construct microscopic models of accreting IMBHs. The mass estimates collected from the literature of all the observational evidence for 137 IMBH-candidates, even though there are still large uncertainties, allow us to undertake a large series of numerical simulations to obtain all their essential physical characteristics.
