Abstract
The results of a study on the delignification of birch wood (Betula pendula L.) by cultivating mushrooms from the genus Pleurotus in laboratory conditions for three time intervals are presented. The results of extraction of lignin from wood by chemical treatment with sodium hydroxide and sodium sulfite in different concentrations, as well as at different processing times, are presented. Difficulties in washing raw materials using highly concentrated solutions have been identified. Data on the study of changes in the content of the main structural and non-structural components of wood, as well as the density of wood in the process of delignification are presented.
