At present, there is an increased interest in the study of fungi in world science. Particular attention is drawn to the representative of a unique group of wood-attacking basidiomycetes - Laricifomes officinalis (Vill.) Kotl. et Pouzar which parasitizes on Larix spp. trunks. It is used in folk and official medicine. At present, the natural resources of this species are depleted. It is listed in many regional Red Books as a rare species. In this connection, the question arises of the expedience of artificial cultivation of this fungus. The goal of this study is a comparative evaluation of the biochemical composition of mycelium and fruit bodies of the fungus L. officinalis. As a result of the research, a comparative biochemical characteristic of the natural fruit bodies and mycelium of L. officinalis cultivated in liquid and solid media was shown. It has been found that the addition of synthetic substances to the nutrient medium increases the amount of biomass. The analysis of biochemical properties showed that the content of extractive substances, carbohydrates and proteins in the mycelium was several times higher than in the fruit body of the fungus. The presence of phospholipids, vitamins (peridoxine, thiamine, riboflavin) and essential amino acids (tyrosine, isoleucine and leucine) in the mycelium is especially valuable. This indicates on the prospects of obtaining mycelia biomass of the fungus. The species L. officinalis is advised as protein substance producer for protein-based feed supplements used in animal farming.
