Splet01. feb. 2009 · Switchgrass is a promising feedstock for bioethanol production, thermal energy conversion and pulping applications. The positive environmental benefits associated with switchgrass include enhancement of wildlife diversity, improvement of soil and water quality, reduced pesticide use and carbon sequestration. SpletHowever, the structural differences among pretreatment-solubilized lignin isolated from switchgrass genotypes have not been extensively investigated. Here, three organosolv pretreatment systems─ethanol (EtOH), tetrahydrofuran (THF), and γ-valerolactone (GVL)─were used on wild-type (WT) and two transgenic switchgrasses. Spletfor ethanol production, switchgrass can be grown on marginal land and would not compete with food crop production. Some researchers have reported that switchgrass can yield five times more energy than it takes to produce it, a substantial improvement over corn’s net energy output.
