Changes in phospholipid composition, phospholipase activity, and accumulation of lipid peroxidation products in mycelium of the lignin-degrading fungus Lentinus (Panus) tigrinus VKM F-3616D in the presence of phenol and lignocellulosic substrates in the cultivation medium are reported. It is shown that in fungal mycelium in the presence of both substrates the share of lysophosphatidylcholine sharply increases. The parity between separate groups of phosphatidylinositols also changes. The lysophosphatidylcholine content increase during cultivation is connected with activation of phospholipase A₂ (EC 3.1.1.4), and phosphatidylinositol parity change is associated with distinctions in affinity of phosphoinositide-specific phospholipase C (EC 3.1.4.11) to them.
