Improved pretreatments applied to the sugarcane bagasse and release of lignin and hemicellulose from the cellulose-enriched fractions by sulfuric acid hydrolysis
(2014)
BACKGROUND A number of pretreatments have been reported in the literature aiming to improve yields with increases in degree of digestibility of the cellulose-enriched fractions, in reducing the process time recalcitrance ...
Two-stage alkaline and acid pretreatment applied to sugarcane bagasse to enrich the cellulosic fraction and improve enzymatic digestibility
(2020-01-01)
Sugarcane bagasse (SB) is made up of cellulose (32-43%), hemicellulose (19-34%) and lignin (14-30%). Due to high recalcitrant nature of SB, pretreatment is required to deconstruct its structure and enrich the cellulosic ...
Incorporation of dithiooxamide as a complexing agent into cellulose for the removal and pre-concentration of Cu(II) and Cd(II) ions from natural water samples
(2013-01-01)
The present study describes the incorporation of a complexing agent, dithiooxamide, into microcrystalline cellulose for use in the pre-concentration of Cu(II) and Cd(II) ions from aqueous samples. The FTIR spectrum of the ...

Pré-tratamento do bagaço de cana-de-açúcar, hidrólise e sua caracterização química e estrutural, visando a produção de etanol de segunda geração
(Universidade Estadual Paulista (Unesp), 2014-04-15)
The fermentation of sugarcane bagasse hydrolyzate (BCA) allows obtaining ethanol 2G. One of the main challenges in this work was to develop methodologies for obtaining rich hydrolysates into glucose for fermentation. Seven ...
Xylan extraction from pretreated sugarcane bagasse using alkaline and enzymatic approaches
(BioMed Central, 2017)
Abstract
Background
New biorefinery concepts are necessary to drive industrial use of lignocellulose biomass components. Xylan recovery before enzymatic hydrolysis of the ...
Stable oxygen isotope records (δ 18 O) of a high-andean cushion peatland in nw Argentina (24° S) imply South American summer monsoon related moisture changes during the late holocene
(Frontiers Media S.A., 2019-02)
High-elevation cushion peatlands are promising archives for paleoenvironmental studies in their extreme habitat of the Central Andean highlands between ∼4000 and 4800 m a.s.l. The Cerro Tuzgle cushion peatland (CTP, 24°09′ ...
