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.

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.

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.
