Lipid composition of Lentinus edodes (Berk.) sing [Lentinula edodes (Berk.) Pegler] fruiting bodies and submerged mycelium

摘要

Comparison of Lentinus edodes with true xylotrophs and humus saprotrophs cultivated under the conditions used in commercial fungal production revealed the following differences in the lipid composition of the fruiting bodies: (1) in L. edodes, fatty acids are characterized by a high C_(16:0) level and the presence of C_(16:1); (2) neutral lipids of L. edodes have a high monoglyceride and free fatty acid content and a low triglyceride level: and (3) the main L. edodes phospholipids are phosphatidylethanolamine and cardiolipin. Fruiting bodies of L. edodes differ from its submerged mycelium in lipid quantity and composition. Submerged mycelium contains up to 20% lipids (fruiting bodies contain 3-4%), neutral lipids are predominantly composed of triglycerides and free fatty acids, and the main constituents of phospholipids are phosphatidylcholine and cardiolipin.
