Search for optimum conditions of sugarcane bagasse hemicellulose extraction
(ELSEVIER SCIENCE SA, 2009)
A process has been elaborated for one-step low lignin content sugarcane bagasse hemicellulose extraction using alkaline solution of hydrogen peroxide. To maximize the hemicellulose yields several extraction conditions were ...
Effect of hemicellulose and lignin on enzymatic hydrolysis of cellulose from brewer`s spent grain
(ELSEVIER SCIENCE INC, 2008)
Enzymatic hydrolysis of brewer`s spent grain in three different forms: original (untreated), pretreated by dilute acid (cellulignin), and pretreated by a sequence of dilute acid and dilute alkali (cellulose pulp), was ...
Extraction and Characterization of Hemicellulose from Eucalyptus By-product: Assessment of Enzymatic Hydrolysis to Produce Xylooligosaccharides
(2019-01-01)
Eucalyptus wood is the primary source of fibers to produce paper and cellulose in South American countries. The major by-product generated in the cellulose industry is sawdust derived from chip wood production, which is ...
Repeated-batch fermentation of sugarcane bagasse hemicellulosic hydrolysate to ethanol using two xylose-fermenting yeasts
(2022-01-01)
In this study, a repeated-batch fermentation of hemicellulosic sugarcane bagasse hydrolysate was investigated to produce bioethanol using two xylose-fermenting yeasts, Scheffersomyces stipitis and Scheffersomyces shehatae. ...
Agroindustrial biomass for xylanase production by Penicillium chrysogenum: Purification, biochemical properties and hydrolysis of hemicelluloses
(2018-05-01)
Background: In this work, the xylanase production by Penicillium chrysogenum F-15 strain was investigated using agroindustrial biomass as substrate. The xylanase was purified, characterized and applied in hemicellulose ...
Lignocellulosic nanofibers from triticale straw: the influence of hemicelluloses and lignin in their production and properties
(Elsevier, 2017-01-07)
The present work aims to determine the influence of hemicellulose and lignin content in the production of lignocellulosic nanofibers (LCNF) from triticale straws. Triticale straws were digested and then gradually delignified, ...
An alternative application to the Portuguese agro-industrial residue: Wheat straw
(HUMANA PRESS INC, 2008)
The effects of alkaline treatments of the wheat straw with sodium hydroxide were investigated. The optimal condition for extraction of hemicelluloses was found to be with 0.50 mol/l sodium hydroxide at 55C for 2 h. This ...
Effect of volumetric oxygen transfer coefficient (kLa) on ethanol production performance by Scheffersomyces stipitis on hemicellulosic sugarcane bagasse hydrolysate
(2016-08-15)
Experimental evaluation of the effect of the agitation speed and aeration rate (measured by kLa) and energy required for ethanol production using sugarcane bagasse hemicellulosic hydrolysate (SBHH) by Scheffersomyces ...
Optimization of acid hydrolysis from the hemicellulosic fraction of Eucalyptus grandis residue using response surface methodology
(Elsevier B.V., 2007-01-01)
Biotechnological conversion of biomass into fuels and chemicals requires hydrolysis of the polysaccharide fraction into monomeric sugars. Hydrolysis can be performed enzymatically and with dilute or concentrate mineral ...
Biochemical conversion of sugarcane straw hemicellulosic hydrolyzate supplemented with co-substrates for xylitol production
(Elsevier B.V., 2016-01-01)
Biotechnological production of xylitol is an attractive route to add value to a sugarcane biorefinery, through utilization of the hemicellulosic fraction of sugarcane straw, whose availability is increasing in Brazil. ...
