Determination of amino acid and fatty acid composition of depth mycelium Lentinus edodes

摘要

The amino acid composition of the proteins of the deep mycelium Lentinus edodes strain 2541 was studied and it was found that the protein contains 17 types of various amino acids, 9 of which (47%) are essential amino acids. Among the essential amino acids, the predominant ones are leucine, lysine, valine and tyrosine. These data indicate the high nutritional value of the mushroom protein. The content of lipids and fatty acids in the cells of the deep mycelium was studied. It was revealed that a significant (75%) part of lipids in the cells is represented by unsaturated fatty acids, the degree of unsaturation of which is 1.46. The main component is the polyunsaturated diene linoleic (C18: 2) acid - 69% of the total fatty acids. Polyunsaturated fattyacids are indispensable components of nutrition, because, like essential amino acids, they cannot be synthesized in the human body.
