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 ligno- cellulosic substrates in the cultivation medium are reported. It is shown that in fungal mycelium in the presence of both sub- strates 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 phospholi- pase 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. © Pleiades Publishing, Ltd., 2010.
