BACKGROUND Fermentable sugars are important intermediates in the biological conversion of biomass. Hemicellulose and amorphous cellulose are easily hydrolyzed to fermentable sugars in dilute acid, whereas crystalline cellulose is more difficult to be hydrolyzed. Cellulose fast pyrolysis is an alternative method to liberate valuable fermentable sugars from biomass. The amount of levoglucosan gen...

BACKGROUND This study is the first to investigate the Brazilian Amazonian Forest to identify new D-xylose-fermenting yeasts that might potentially be used in the production of ethanol from sugarcane bagasse hemicellulosic hydrolysates. METHODOLOGY/PRINCIPAL FINDINGS A total of 224 yeast strains were isolated from rotting wood samples collected in two Amazonian forest reserve sites. These samp...

Sugarcane bagasse was torrefied to improve its quality in terms of properties prior to gasification. Torrefaction was undertaken at 300 °C in an inert atmosphere of N₂ at 10 °C·min-1 heating rate. A residence time of 5 min allowed for rapid reaction of the material during torrefaction. Torrefied and untorrefied bagasse were characterized to compare their suitability as feedstocks for gasificati...

The present study involves production of cellulolytic enzymes by a newly isolated strain of Aspergillus niger isolated from decaying sugarcane bagasse. Solid-state-fermentation was employed using sweet sorghum bagasse as the substrate for the production of enzyme. One factor at a time approach was used to optimize the process variables like moisture content, pH, temperature, and incubation peri...

sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. so it is can be used as a sugar source in many processes. lignin and hemicellulose must be removed before hydrolysis of cellulose. several different pretreatment approaches have been studied. the purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

Hydrothermal carbonization of sugarcane bagasse using wet torrefaction is studied. The biomass is torrefied in water or dilute sulfuric acid solution and microwaves are employed to heat the solutions where the reaction temperature is fixed at 180 °C. The effects of acid concentration, heating time and solid-to-liquid ratio on the performance of wet torrefaction are investigated. It is found tha...

Vortex based hydrodynamic cavitation and anaerobic digestion sugarcane bagasse biorefineries for revitalising the sugar industry.

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...

In this study, solid-state fermentation of two types of agricultural residues/products for lipase production in a tray-bioreactor was investigated. Rhizopus oryzae was used as a potential fungus strain and two types of agricultural residues including soybean meal and sugarcane bagasse were utilized as substrate. Fermentation was carried out in two different operational conditions: one with cont...

Sugarcane Bagasse is one of the wastes come out from sugarcane water milling which currently very much and abundant in Pidie. Since this garbage cannot naturally disintegrate, it might harm environment. One way to manage bagasse by processing become compost. This study examined results composting using a reduction treatment material size addition several types bioactivators that aim accelerate ...
