| Summary: | Currently, due to the reduction of pollutant emissions from transport and the obligations arising from the RED II Directive, there is a great need to develop alternative solutions directly affecting the quantity and quality composition of advanced biofuels. The study evaluated the impact of acid, alkaline, and laccase treatment of sorghum biomass in obtaining lignocellulosic ethanol and optimized them. The effect of H2SO4, NaOH, and laccase on the value of reducing sugars and the chemical composition of the solid fraction before and after the treatment was determined. Sorghum biomass before and after the pretreatment was analyzed by FTIR spectra and SEM. Then, the SSF process was carried out and the ethanol yield per 100 g of sorghum biomass was determined. In summary, sorghum biomass was found to be an interesting and promising source for use in bioethanol production. It was found that alkaline and laccase treatment of sorghum biomass are effective methods and are based mainly on delignification. The advantage of biomass laccase treatment is the low energy demand, the use of relatively inexpensive equipment, and the production of pollutants with a low environmental burden. |
