Optimization of Enzymatic saccharification conditions for acid treated bmr sorghum biomass was studied with the inhouse enzyme produced from Aspergillus sp.. Optimization of enzyme loading, substrate concentration, temperature and time yielded a maximum of 416.00 ± 0.55 mg/g sugars with an improved hydrolysis efficiency of 55.97 ± 0.45%. Protein adsorption onto lignocellulosic substance was inv...

Pretreatment is very important for the efficient production of value-added products from lignocellulosic biomass. However, traditional pretreatment methods have several disadvantages, including low efficiency and high pollution. This article gives an overview on the applications of ionic liquids (ILs) and IL-based solvent systems in the pretreatment of lignocellulosic biomass. It is divided int...

Conversion of lignocellulosic biomass to fuel ethanol involves pretreatments followed by enzyme-catalyzed hydrolysis to generate fermentable sugars. Efficient pretreatment method can significantly enhance hydrolysis of biomass and thus reduce ethanol production cost. Cellulosic plant materials are mainly composed of cellulose, hemicellulose and lignin, the cheapest source of fermentable sugars....

In this study, total 80 typical Miscanthus accessions were examined with diverse lignocellulose features, including cellulose crystallinity (CrI), degree of polymerization (DP), and mole number (MN). Correlation analysis revealed that the crude cellulose CrI and MN, as well as crystalline cellulose DP, displayed significantly negative influence on biomass enzymatic digestibility under pretreatm...

Unbleached pulp from the pulp and paper industry was used as a cellulosic material source to produce bioethanol in a separate hydrolysis and fermentation process. In the batch enzymatic saccharification, three cellulolytic enzymes and different initial carbohydrate (CH) contents were tested. Cellic CTec2 was shown to be the most efficient enzyme with the lowest dosage used: 35 FPU gCH . Sugar p...

In Brazil, the production of ethanol from sugarcane produces large amounts of lignocellulosic residues (bagasse and straw), which have been driving research and development for the production of second generation ethanol. In the present work, a recombinant Saccharomyces cerevisiae strain expressing the βglucosidase gene from Humicola grisea was used for ethanol production from three different c...
