Waste Paper - Promissing Feedstock for Bioethanol Production
Modern approach to utilization of non-edible biomass is its conversion to glucose, and the following fermentation of the sugar into final bioproducts. Among various biomass types, the waste of office paper is distinguished by increased content of cellulose and negligible content of lignin; therefore it can be a suitable feedstock for bioconversion into valuable bioproduct, e.g. ethanol. An adva...
متن کاملDetoxification of Lignocellulosic Hydrolysates for Improved Bioethanol Production
Lignocelluloses are the most abundant raw materials on Earth comprised of cellulose, hemicelluloses and lignin. After cellulose, hemicellulose is the principal fraction of the plant cell wall that could serve as a potential substrate for the production of value-added products under optimized conditions [Chandel & Singh, 2011; Chandel et al., 2010a; Hahn-Hagerdal et al., 2007; Saha, 2003]. Large...
متن کاملHydrothermal and Acid Pretreatments Improve Ethanol Production from Lignocellulosic Biomasses
Hydrothermal and acid pretreatments using different acid charges (1.5%, 3.0%, and 4.5% H2SO4) were proposed for eucalyptus, sugarcane bagasse, and sugarcane straw prior to their bioconversion into ethanol using the semi-simultaneous saccharification and fermentation (SSSF) process. The hydrothermal and acid pretreatments were efficient for hemicelluloses removal from eucalyptus (63 to 96%), bag...
متن کاملRaman Imaging of Lignocellulosic Feedstock
The main structural plant cell wall polymers cellulose, hemicelluloses, and lignin rank amongst the most abundant biopolymers in Earth’s carbon cycle. These three polymers form the lignocellulose complex and constitute the bulk of the cell wall with 40-50%, 10-40% and 5-30% of biomass by weight, respectively [1, 2]. Its highly ordered structure of cellulose microfibril aggregates, embedded in a...
متن کاملPretreatments and Factors Affecting Saccharification and Fermentation for Lignocellulosic Ethanol Production
Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source for sustainable energy production and has the potential to be a valuable substitute. Various pretreatment techniques change the physical and chemical structures of the lignocellulosic biomass and improve the hydrolysis rate. The cost of ethanol production from lignocellulosic material is relatively...
