Methods for Long-Term Storage of Pure Cultures of Macrofungi

Basidiomycetous macrofungi have significant biotechnological potential and are promising objects for use in va-rious industrial sectors, such as food production, pharmaceuticals, the production of active compounds and polysaccharides. The industrial use of macrofungi implies the presence of large collections of cultures using sto-rage protocols that ensure the preservation of viability, reproduction, genetic stability and the ability to produce active compounds. With the expansion of the list of industrially used species, it is advisable to develop new protocols for the storage of strains and optimize the existing ones for new, promising types of macrofungi. It seems necessary to study in detail the effect of long periods of storage on morphological and cultural characteristics, genetic stability, enzymatic activity, and the ability to form sexual structures.
