The influence of variety type on dilute acid pretreatment-hydrolysis responses of sugarcane bagasse
This study evaluated the influence of variety type on dilute acid pretreatment and enzymatic hydrolysis responses in terms of xylose, glucose and total combined sugar yields of eight varieties of sugarcane bagasse. The pretreatment was carried out in small tubular reactors. The materials were pretreated under five different conditions and hydrolysed with a standard enzyme dosage (15 FPU/g water...
متن کاملComparative hydrolysis and fermentation of sugarcane and agave bagasse.
Sugarcane and agave bagasse samples were hydrolyzed with either mineral acids (HCl), commercial glucanases or a combined treatment consisting of alkaline delignification followed by enzymatic hydrolysis. Acid hydrolysis of sugar cane bagasse yielded a higher level of reducing sugars (37.21% for depithed bagasse and 35.37% for pith bagasse), when compared to metzal or metzontete (agave pinecone ...
متن کاملDirect hydrogen production from dilute-acid pretreated sugarcane bagasse hydrolysate using the newly isolated Thermoanaerobacterium thermosaccharolyticum MJ1
BACKGROUND Energy shortage and environmental pollution are two severe global problems, and biological hydrogen production from lignocellulose shows great potential as a promising alternative biofuel to replace the fossil fuels. Currently, most studies on hydrogen production from lignocellulose concentrate on cellulolytic microbe, pretreatment method, process optimization and development of new ...
متن کاملFractal-like Kinetic Analysis on the Enzymatic Hydrolysis of Liquid Hot Water, Hydrochloric Acid and Sodium Hydroxide Pretreated Sugarcane Bagasse
LHW (liquid hot water), HCl (hydrochloric acid) and NaOH (sodium hydroxide) were used to pretreat sugarcane bagasse (SB), and composition assay showed that the carbohydrate content in NaOH pretreated SB got to 84.3% and lignin decreased to 3.4%, while the LHW and HCl pretreatments brought similar composition changes, where the carbohydrate content reached 61.2% and 66.6%, respectively, and the ...
متن کاملXylan extraction from pretreated sugarcane bagasse using alkaline and enzymatic approaches
Background New biorefinery concepts are necessary to drive industrial use of lignocellulose biomass components. Xylan recovery before enzymatic hydrolysis of the glucan component is a way to add value to the hemicellulose fraction, which can be used in papermaking, pharmaceutical, and food industries. Hemicellulose removal can also facilitate subsequent cellulolytic glucan hydrolysis. Results...
