BACKGROUND The development of technological routes to convert lignocellulosic biomass to liquid fuels requires an in-depth understanding of the cell wall architecture of substrates. Essential pretreatment processes are conducted to reduce biomass recalcitrance and usually increase the reactive surface area. Quantitative three-dimensional information about both bulk and surface structural featur...
Ionic liquid pretreatment of biomass has been shown to greatly reduce the recalcitrance of lignocellulosic biomass, resulting in improved sugar yields after enzymatic saccharification. However, even under these improved saccharification conditions the cost of enzymes still represents a significant proportion of the total cost of producing sugars and ultimately fuels from lignocellulosic biomass...
Cellulases are enzymes that attracting worldwide attention because of their ability to degrade cellulose in the lignocellulosic biomass and transform it into highly demanded bioethanol. The enzymatic hydrolysis by cellulases fermentable sugars is a crucial step biofuel production, given complex structure lignocellulose. Due cellulases’ unique hydrolyze very recaltricant nature biomass, cellulas...
Lignocellulosic biomass, as the largest amount of carbohydrate forms on our planet, has great potential a feedstock for sustainable chemical and material production. However, its conversion is still challenging due to rigid structure complicated composition. It mainly composed cellulose, hemicellulose, lignin. Cellulose linear polymer consisting glucose linked by β-(1,4)glycosidic bonds. Hydrog...
This review presents data on the chemical composition of harvest residues and food <br /> industry by-products as widely abundant representatives lignocellulosic waste biomass. Pretreatment methods, with special emphasis biological are presented an important step in utilization biomass for production sustainable biofuels high-value chemicals. Special attention was paid to methods lignin i...
Bioenergy should play an essential part in reaching targets to replace petroleum-based transportation fuels with a viable alternative, and in reducing long-term carbon dioxide emissions, if environmental and economic sustainability are considered carefully. Here, we review different platforms, crops, and biotechnology-based improvements for sustainable bioenergy. Among the different platforms, ...
