Thermal characterization of lignocellulosic residue from different sugarcanes
Bagasse samples from four different sugarcane were directly collected as the residues of milling in a processing plant. The samples were dried at 105 A degrees C, compressed to small granules and then their TG/DTA and DSC ...
Alkaline pretreatment of Mexican pine residues for bioethanol production
(African Journal of Biotechnology, 2013-07-31)
Vegetal fibers in polymeric composites: a review
(Assoc Brasil Polimeros, 2015-01-01)
The need to develop and commercialize materials containing vegetal fibers has grown in order to reduce environmental impact and reach sustainability. Large amounts of lignocellulosic materials are generated around the world ...
PRODUCTION OF SOLUBLE LIGNIN-RICH FRAGMENTS (APPL) FROM WHEAT LIGNOCELLULOSE BY STREPTOMYCES-VIRIDOSPORUS AND THEIR PARTIAL METABOLISM BY NATURAL BACTERIAL ISOLATES
(ELSEVIER SCIENCE BV, 1990-02)
The actinomycete Streptomycetes viridosporus attacks wheat lignocellulose releasing soluble lignin-rich fragments (APPL). Chemical analyses indicated that these APPL contain 20% less guaiacyl and 70% less glucose residues ...
Biochar and soil nitrous oxide emissions.
(Pesquisa Agropecuária Brasileira, Brasília, DF, v. 47, n. 5, p. 722-725, maio 2012., 2012)
Second-generation ethanol from pineapple leaf fibers
The use of different lignocellulosic residues for the production of cellulosic ethanol is an alternative for the expanding demand of this fuel without increasing the planting area of traditional carbohydrate crops. One of ...
The effect of a lytic polysaccharide monooxygenase and a xylanase from Gloeophyllum trabeum on the enzymatic hydrolysis of lignocellulosic residues using a commercial cellulase
Hydrolysis of lignocellulosic biomass depends on the concerted actions of cellulases and accessory proteins. In this work we examined the combined action of two auxiliary proteins from the brown rot fungus Gloeophyllum ...
Cr(VI) and Cr(III) removal from aqueous solution by raw and modified lignocellulosic materials: a review
(Elsevier Science, 2010-08)
In aqueous systems, chromium usually exists in both trivalent and hexavalent oxidation states, being Cr(VI) of particular importance and concern due to its great toxicity. Industrial sources of Cr(VI) are leather tanning, ...
