Abstract

The aim of the study was to evaluate the biochemical possibilities of converting waste lignocellulosic biomass to second generation bioethanol. Three substrates were used in the research: barley straw, rye straw and triticale straw. In the first stage of the research bacterial strains capable of converting waste biomass to produce sugars used to produce energy-useful ethanol were selected. Of the eight strains isolated the three with the highest potential were selected on the basis of activity index value. The raw materials were subjected to enzymatic hydrolysis using the simultaneous saccharifi cation and fermentation method (SSF process). Based on the conducted research, it was found that the examined waste biomass is suitable for the production of cellulosic bioethanol. As a result of distillation 10% and 15% (v/v) ethanol was obtained, depending on the strain and the type of raw material. It was demonstrated that the bacterial strain had a greater impact on the effectiveness of the process than the type of straw used.
