Effect of lignin content on cellulolytic saccharification of liquid hot water pretreated sugarcane bagasse
(2020-01-31)
Lignin contributes to the rigid structure of the plant cell wall and is partially responsible for the recalcitrance of lignocellulosic materials to enzymatic digestion. Overcoming this recalcitrance is one the most critical ...
EFFECT OF RESIDUAL LIGNIN AND HEXENURONIC ACIDS ON THE GENERATION OF ORGANOCHLORINES WITH CHLORINE DIOXIDE
(Editura Acad Romane, 2019-01-01)
The pulp and paper industry is one of the leading economic sectors that contribute to the contamination of the environment because of the use of organochlorine compounds, especially during the pulp bleaching process. For ...
Effect of residual lignin and hexenuronic acids on the generation of organochlorines with chlorine dioxide
(2019-01-01)
The pulp and paper industry is one of the leading economic sectors that contribute to the contamination of the environment because of the use of organochlorine compounds, especially during the pulp bleaching process. For ...
EFFECT OF KRAFT PULPING TEMPERATURE AND ALKALINITY ON EUCALYPTUS ECF BLEACHING
(Editura Acad Romane, 2016-10-01)
The effects of eucalyptus kraft pulping conditions on subsequent bleaching were investigated. Three samples of industrial eucalyptus chips underwent haft pulping with different alkalinities and hexenuronic acid (HexA) ...
Modelo de otimização para seleção de árvores matrizes de Eucalyptus grandis
(2002-06-01)
Individual data of basic density and volume of wood, pulp kappa number, soluble lignin, cost of pulping process as well as gravimetric gross yield of pulping process were used from 64 trees of Eucalyptus grandis W. Hill ...

The distribution of lignin and xylan in the inner and surface layers of the fiber from eucalyptus kraft pulp and its effects on oxygen delignification
(2017-07-01)
The chemical structure and composition of lignin and hemicellulose, as well as the distribution between inner and outer layers of fiber, can adversely affect bleaching operations or fiber-fiber bond on pulp and, consequently ...
Limitation of cellulose accessibility and unproductive binding of cellulases by pretreated sugarcane bagasse lignin
(BioMed Central, 2017)
Abstract
Background
The effectiveness of the enzymatic hydrolysis of cellulose in plant cell wall is strongly influenced by the access of enzymes to cellulose, which is at ...
Reaction rates of lignin and hexenuronic acids with chlorine dioxide, ozone, and a sulfuric acid
(2008-04-01)
The reaction rates of lignin and hexenuronic acids (HexA) with chlorine dioxide, ozone, and sulfuric acid were investigated. In unbleached and oxygen-delignified eucalyptus kraft pulps containing both lignin and HexA, only ...
Sugarcane biomass conversion influenced by lignin
(2020-03-01)
Plant biomass residues are renewable sources for the production of biofuels and high-value macromolecules. Sugarcane bagasse is one such plant biomass residue that is available from the sugar-processing industry. It is ...
