LIGNOCELLULOSIC BIOMASS AFTER EXPLOSIVE AUTOHYDROLYSIS AS SUBSTRATE TO BUTANOL OBTAINING

28 Lignocellulose is one of the virtually unlimited sources by the number of substrates for microbial conversion. A lot of lignocellulosic waste is produced in forestry and agriculture, pulp and paper and wood industries, which poses a serious environmental problem, the increasing pollution. Unfortunately, most of the waste is not recycled although it can be used, for example as biofuels. An effective biological conversion requires pretreatment of lignocellulosic biomass [1]. One of the methods of its complex pretreatment is explosive autohydrolysis. This method provides almost total destruction of the biomass and allows to separate components of lignocellulosic material [2]. Later lignocellulosic biomass components can serve as a substrate for microbial conversion, including microorganisms of the genus Clostridium, and as a source for obtaining biofuels such as butanol [3]. The aim of the study was to explore the effect of explosive autohydrolysis on lignocellulosic biomass (saving, switchgrass biomass) for consequent use as a substrate to produce biofuels such as butanol.
