Two-stage treatments of sugarcane bagasse with steam and alkaline peroxide were performed and the hemicelluloses extracted were characterized by chemical methods, SEC-MALLS, FT-IR and 13C NMR. The hemicellulose from steam pretreatment was found to contain galacto-arabinoxylans while alkaline peroxide extraction yielded predominately linear arabinoxylans.The present studyshowed a promising seque...

Bioethanol is one of the most important alternative renewable energy sources that substitute the fossil fuels. Sugarcane bagasse has a content of cellulose and hemicelluloses, which make it suitable as fermentation substrate when hydrolyzed. The objective of work is ethanol production from sugarcane bagasse (SCB) by the fermentation process. Eight laboratory experiments were conducted to produc...

The market for mats and blankets made from natural fibers is a rapidly growing segment of the erosion control industry. In south Louisiana, bagasse is a local, readily available material with properties that make it suitable for erosion control products. In the framework of work towards diversifying the sugarcane industry, a prototype of a simple continuous device to produce erosion control mat...

A new method of graphene oxide (GO) synthesis via single-step reforming of sugarcane bagasse agricultural waste by oxidation under muffled atmosphere conditions is reported. The strong and sharp X-ray diffraction peak at 2θ = 11.6° corresponds to an interlayer distance of 0.788 nm (d002) for the AB stacked GOs. High-resolution transmission electron microscopy (HRTEM) and selected-area electron ...

Activated carbon is used in sugar industries for the removal of colorants from sugar liquor and for treatment of drinking water and industrial wastewater. Coal is a commercially used activated carbon, which is a limited non renewable resource. There are different renewable resources such as sugarcane Bagasse, Almond nutshells, Rice husk, Rice straw, Coconut shells, which could be used as altern...

Sugarcane bagasse is an important lignocellulosic material studied for the production of xylooligosaccharides (XOS). Some XOS are considered soluble dietary fibre, with low caloric value and prebiotic effect, but they are expensive and not easily available. In a screening of 138 fungi, only nine were shortlisted, and just Aspergillus fumigatus M51 (35.6 U/mL) and A. fumigatus U2370 (28.5 U/mL) ...

This study examines the fermentation of autohydrolyzed and 1-n-butyl-3methylimidazolium acetate (C4mimOAc) pretreated sugarcane bagasse, using four different yeast strains to determine the efficiency of bioethanol production. Three strains of Saccharomyces cerevisiae (S. cerevisiae) and one of Scheffersomyces stipitis (S. stipitis) were employed in this study. It was observed that the sugarcane...

Background The international energetic system strongly depends on fossil fuels, which causes negative effects in the environment, such as the global warming. Biofuels appear as an environmental and economic alternative for the energetic industry because of their potential source of renewable energy. Several studies are based on sugarcane culture and its derivatives, as bagasse, the sugarcane re...

BACKGROUND Considering that the costs of cellulases and hemicellulases contribute substantially to the price of bioethanol, new studies aimed at understanding and improving cellulase efficiency and productivity are of paramount importance. Aspergillus niger has been shown to produce a wide spectrum of polysaccharide hydrolytic enzymes. To understand how to improve enzymatic cocktails that can h...

Sugarcane bagasse and trash may be used as feedstock for second generation ethanol production. Production of second generation ethanol integrated with first generation plants processing sugarcane presents several advantages over the stand-alone second generation ethanol production process; however, bagasse is used as fuel to supply the energy demand of the first generation process, so the amoun...
