Lignin chemistry and topochemistry during kraft delignification of Eucalyptus globulus genotypes with contrasting pulpwood characteristics
(Walter De Gruyter Gmbh, 2014-08-01)
Eucalyptus globulus Labill. is a short-fibre resource for pulp and paper production. Ten different E. globulus genotypes with varied pulpwood quality and chemical composition were evaluated under kraft pulping conditions. ...
Studies of lignin as reinforcement for plastics composites
(2016-03-23)
The growing environmental concerns and depletion of fossil fuels resulted in an increased interest in environmentally friendly materials based on natural polymers. Efforts are being made to introduce the lignin in plastic ...
Physico-chemical characteristics and pyrolysis behavior of klason lignins isolated from agro-industrial biomass
(Taylor, 2015-07)
Klason lignins lab-isolated from two lignocellulosic biomasses emerging from the processing of agro-industrial products, Aspidosperma australe wood sawdust and Bertholletia excelsa nutshells, with different contents of ...

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 ...
Structural characterization of sugarcane lignins extracted from different protic ionic liquid pretreatments
(2020-12-01)
Previous studies based on protic ionic liquids have shown them to be effective for extracting lignins from biomass. Moreover, ILs synthesized with amine cations can promote the insertion of nitrogen into lignin, favoring ...
Lignins from sugarcane bagasse: Renewable source of nanoparticles as Pickering emulsions stabilizers for bioactive compounds encapsulation
(2019-11-15)
Lignin nanoparticles has gained interest in recent years in a wide range of applications due to its unique properties compared to the microsized material. Furthermore, lignin is obtained from lignocellulosic biomass ...
Métodos de extração e aproveitamento da lignina proveniente de biomassa vegetal
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Química - EQ, 2020-12-14)
Lignin is one of the most widely available biopolymers in the nature, being less abundant only when compared to cellulose. It is a three-dimensional shaped molecule, with a complex and highly branched phenolic structure. ...
Characterization of coffee (Coffea arabica) husk lignin and degradation products obtained after oxygen and alkali addition
(2018-06-01)
The full use of biomass in future biorefineries has stimulated studies on utilization of lignin from agricultural crops, such as coffee husk, a major residue from coffee processing. This study focuses on characterizing the ...
Fragmentation of lignin from organosolv black liquor by white rot fungi
(North Carolina State Univ Dept Wood &paper Sci, 2015-01-01)
The mycelial growth ability of 13 white rot fungi were separately evaluated in kraft, organosolv, and soda black liquor agar-plates. The fungus able to best grow and decolorize black liquor agar-plates was grown in organosolv ...
