Riassunto analitico
The conversion of lignocellulosic biomass into monosaccharides and then, after, ethanol, can be made bio-chemically, through acid or enzymatic hydrolysis; the latter is an extremely complex multi-enzyme process, which requires that the biomass is pretreated, as the lignocellulosic materials are structured to resist the action of physical, chemical and biological external agents.<br><br>The pretreatment is therefore intended to expose as much as possible to the next action of cellulose enzymes, capable of breaking the chain of the cellulose obtaining glucose.<br><br>This work reports a pretreatment test for the 2G ethanol conversion of llignocellulosic biomass, in this case spelt straw harvested in the region of Garfagnana, Italy; all the experimental campaign was carried out at the Laboratorio Bioetanol, property of Chemistry Institute of the Federal University of Rio de Janeiro.<br><br>
