Detoxification 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 کاملRecycling of cellulases in lignocellulosic hydrolysates using alkaline elution.
The recovery of cellulases from lignin, lignocellulosic hydrolysates and cellulose by alkaline washes at pH 9 and 10 was examined. The effect of the pH on the structural stability of purified Cel7A was analyzed by circular dichroism. Purified Cel7A showed conformational changes at pH 9 and 10 that were reversible at pH 4.8. Temperature influenced the enzymatic hydrolysis of wheat straw and may ...
متن کاملControl of fermentation of lignocellulosic hydrolysates
In this work substrate feeding rate to a fermentation of lignocellulose hydrolysate for production of ethanol has been studied. During hydrolysis of lignocellulose inhibitors are formed that effect the microorganism (here Saccharomyces cerevisiae) that ferments the sugar to ethanol in a negative way. To make the hydrolysate fermentable the inhibitors are often removed by detoxification prior to...
متن کاملHydrolysates of lignocellulosic materials for biohydrogen production
Lignocellulosic materials are commonly used in bio-H2 production for the sustainable energy resource development as they are abundant, cheap, renewable and highly biodegradable. In the process of the bio-H2 production, the pretreated lignocellulosic materials are firstly converted to monosaccharides by enzymolysis and then to H2 by fermentation. Since the structures of lignocellulosic materials...
متن کاملThe Electroanalytical Determination of Sodium Borohydride Using a Gold Electrode
Sodium borohydride or sodium tetrahydroborate is used as a reducing agent in many organic and inorganic reactions. Therefore, the determination of sodium borohydride present in the system is of great importance. Borohydride releases hydrogen under appropriated conditions in the presence of a suitable catalyst. Since the amount of hydrogen emitted is proportional to the amount of borohydride, th...
