Evaluation of lignin contents in tropical forages using different analytical methods and their correlations with degradation of insoluble fiber
(Elsevier Science BV, 2011)
We compared the lignin contents of tropical forages by different analytical methods and evaluated their correlations with parameters related to the degradation of neutral detergent fiber (NDF). The lignin content was ...
Use of lignin extracted from different plant sources as standards in the spectrophotometric acetyl bromide lignin method
(Amer Chemical Soc, 2011)
A nongravimetric acetyl bromide lignin (ABL) method was evaluated to quantify lignin concentration in a variety of plant materials. The traditional approach to lignin quantification required extraction of lignin with acidic ...
Development of high bio-content polypropylene composites with different industrial lignins
Sustainability, eco-efficiency, pollution prevention, industrial ecology, and green chemistry are considering platform-based approaches to the development of the next generation of products and processes. Recently, renewable ...
Thiourea effect on the lignin biodegradation
Lignin degradation by peroxidase or an extracellular crude ligninase in the presence of thiourea is enhanced. Veratryl alcohol, exhibits the same behaviour in both cases. Thiourea is proposed as an additive in biopulping
Thermal Characteristics of Lignin Residue from Industrial Processes
(North Carolina State Univ Dept Wood & Paper Sci, 2014-01-01)
Many pulp mills and biorefineries today are focusing on the utilization of their residual lignin for economic return. Although lignin can be burned to produce energy, it also has the potential for the production of value-added ...
Eucalyptus organosolv lignins: study of the hydroxymethylation and use in resols

LIGNIN DEGRADATION DURING SOFTWOOD DECAYING BY THE ASCOMYCETE CHRYSONILIA-SITOPHILA
(Kluwer Academic PublDordrechtHolanda, 1995)
Chemical properties and decay resistance of eucalyptus grandis wood from steamed logs
The objective of this study was evaluate the effect of the log steaming on the chemical properties and decay resistance of Eucalyptus grandis wood. Logs with diameter between 20 and 22 cm were studied. Half of logs were ...
Atomic force microscopy (AFM) investigation of Langmuir-Blodgett (LB) films of sugar cane bagasse lignin
