| Summary: | <p><em>The second generation of bioethanol derived from various cellulosic biomass materials is one of the</em><em> latest</em><em> </em><em>renewable</em><em> energy as the</em><em> alternative</em><em> of fossil fuel. The cellulosic waste based wood and non-wood materials are the most abundant natural resource on the earth, renewable, and inexpensive. Currently, second generation bioethanol development is still not optimally done due to various obstacles, especially the pretreatment process to eliminate lignin, influencing the conversion process of cellulose into reducing sugar. Hydrothermal method is one of lignocellulose pretreatments, which is widely developed because this method is relatively cheap and environmentally friendly with the utilization of water-based solvent. Hydrothermal methods performed at high temperature and pressure in a</em><em> </em><em>relatively short time are able to deconstruct the li</em><em>gno</em><em>cellulose structure that enables cellulase enzymes to access cellulose for hydrolysis. This study discussed about the development of hydrothermal method for lignocellulose pretreatment process to increase production of second-generation bioethanol. Some aspects studied in this research were structural change, chemical composition, lignocellulosic</em><em> </em><em>crystallinity before and after hydrothermal processes, and hydrothermal effect on the production of reducing sugars. H</em><em>ydrothermal method c</em><em>ould</em><em> be used and developed as an efficient and cheap method </em><em>as the</em><em> first treatment of lignocellulose waste in attempt to increase </em><em>the </em><em>produc</em><em>tion of</em><em> bioethanol</em><em>.</em><strong></strong></p> |
