Journal ArticleDOI
Biodegradation of lignocellulosics: microbial, chemical, and enzymatic aspects of the fungal attack of lignin.
Ángel T. Martínez,Mariela Speranza,Francisco J. Ruiz-Dueñas,Patricia Ferreira,Susana Camarero,Francisco Guillén,Francisco Guillén,María Jesús Martínez,Ana Gutiérrez,José C. del Río +9 more
TL;DR: Broadening the knowledge of lignocellulose biodegradation processes should contribute to better control of wood-decaying fungi, as well as to the development of new biocatalysts of industrial interest based on these organisms and their enzymes.
Journal ArticleDOI
Structural Characterization of Wheat Straw Lignin as Revealed by Analytical Pyrolysis, 2D-NMR, and Reductive Cleavage Methods
José C. del Río,Jorge Rencoret,Jorge Rencoret,Pepijn Prinsen,Ángel T. Martínez,John Ralph,Ana Gutiérrez +6 more
TL;DR: The structure of the lignin in wheat straw has been investigated by a combination of analytical pyrolysis, 2D-NMR, and derivatization followed by reductive cleavage, and a major new finding is that the flavone tricin is apparently incorporated intoThe lignins.
Journal ArticleDOI
Enzymatic delignification of plant cell wall: from nature to mill
Ángel T. Martínez,Francisco J. Ruiz-Dueñas,María Jesús Martínez,José C. del Río,Ana Gutiérrez +4 more
TL;DR: Enzymatic delignification will be soon at the pulp mill (combined with pitch removal) and understanding of the reactions produced will increase by using modern techniques for lignin analysis, and the already-known ligninolytic oxidoreductases are being improved using protein engineering.
Journal ArticleDOI
Paper pulp delignification using laccase and natural mediators
TL;DR: In this article, three plant phenols, namely acetosyringone, syringaldehyde and p-coumaric acid, were selected as laccase redox mediators to investigate the enzymatic delignification of paper pulp (obtained from kraft cooking of eucalypt wood) in combination with peroxide bleaching.
Journal ArticleDOI
Lignin Composition and Structure in Young versus Adult Eucalyptus globulus Plants
Jorge Rencoret,Ana Gutiérrez,Lidia Nieto,Jesús Jiménez-Barbero,Craig B. Faulds,Hoon Kim,John Ralph,Ángel T. Martínez,José C. del Río +8 more
TL;DR: The data indicated that p-hydroxyphenyl and guaiacyl units are deposited at the earlier stages, whereas the woods are enriched in syringyl (S) lignin during late lignification, and resinols are the most important nonether linkages.
