Biodegradation of lignocellulosics: microbial, chemical, and enzymatic aspects of the fungal attack of lignin.
TLDR
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. Expand
The Paleozoic Origin of Enzymatic Lignin Decomposition Reconstructed from 31 Fungal Genomes
TLDR
Comparative analyses of 31 fungal genomes suggest that lignin-degrading peroxidases expanded in the lineage leading to the ancestor of the Agaricomycetes, which is reconstructed as a white rot species, and then contracted in parallel lineages leading to brown rot and mycorrhizal species. Expand
Lignin-Derived Compounds as Efficient Laccase Mediators for Decolorization of Different Types of Recalcitrant Dyes
TLDR
Phenolic aldehydes, ketones, acids, and esters related to the three lignin units were among the best mediators, including p-coumaric acid, vanillin, acetovanillone, methyl vanillate, and above all, syringaldehyde and acetosyringone, which are especially promising as ecofriendly (and potentially cheap) mediators for industrial applications. Expand
Genome, transcriptome, and secretome analysis of wood decay fungus Postia placenta supports unique mechanisms of lignocellulose conversion
TLDR
Comparisons with the closely relatedwhite-rot fungus Phanerochaete chrysosporium support an evolutionary shift from white-rot to brown-rot during which the capacity for efficient depolymerization of lignin was lost. Expand
Molecular biology and structure-function of lignin-degrading heme peroxidases
TLDR
Chemical and site-directed mutagenesis modification confirmed that an exposed tryptophan is involved in veratryl alcohol oxidation however, multiple sites could be responsible for oxidation of different aromatic substrates and dyes by these peroxidases. Expand
Versatile peroxidase oxidation of high redox potential aromatic compounds: site-directed mutagenesis, spectroscopic and crystallographic investigation of three long-range electron transfer pathways.
TLDR
High-resolution crystal structures as well as homology models of VP isoenzymes from the fungus Pleurotus eryngii revealed three possibilities for long-range electron transfer for the oxidation of high redox potential aromatic compounds. Expand
Microbial degradation of lignin: how a bulky recalcitrant polymer is efficiently recycled in nature and how we can take advantage of this
TLDR
The structure–function information currently available is being used to build tailor‐made peroxidases and other oxidoreductases as industrial biocatalysts. Expand
Laccase detoxification of steam-exploded wheat straw for second generation bioethanol.
TLDR
The action of phenolic compounds as fermentation inhibitors, and the advantages of a laccase treatment to increase the ethanol production from steam-exploded wheat straw are demonstrated. Expand
Fungal pretreatment: An alternative in second-generation ethanol from wheat straw.
TLDR
Most fungi degraded lignin with variable selectivity degrees, although only eight of them improved sugar recovery compared to untreated samples, and no close correlations were found between ligninolytic enzymes production and sugar yields. Expand
Enzymatic delignification of plant cell wall: from nature to mill.
TLDR
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. Expand
