文摘

The addition of an antioxidant (2-ethyl-6-methyl-3-hydroxypyridine hydrochloride) to a culture of the fungus Lentinus tigrinus growing on a medium with lignosulfonate inhibited growth and changed the composition of cell phospholipids. The ratio of lipid messengers also changed, the phosphatidic acid level decreased, and the content of phosphatidylinositol dramatically increased. The substitution of lignosulfonate with glucose and the addition of an antioxidant increased the biomass yield of L. tigrinus, as well as that of another fungus, Cunninghamella japonica, which was incapable of biodegrading the biopolymer. The obtained results indicate the specificity of growth processes in the presence of lignosulfonate and confirm the role of free radical oxidation reactions in the biodegradation of this biopolymer by L. tigrinus.
