Fungal laccases - occurrence and properties.
TL;DR: The fact that laccases only require molecular oxygen for catalysis makes them suitable for biotechnological applications for the transformation or immobilization of xenobiotic compounds.

Review: lignin conversion by manganese peroxidase (MnP)
TL;DR: The review summarizes and discusses different approaches to prove lignin decomposition in vitro and lists, in addition, other recalcitrant substances oxidizible by MnP.

Lignin degradation: microorganisms, enzymes involved, genomes analysis and evolution.
Grzegorz Janusz,Anna Pawlik,Justyna Sulej,Urszula Świderska-Burek,Anna Jarosz-Wilkołazka,Andrzej Paszczynski +5 more
TL;DR: A detailed description of low molecular weight compounds is presented, which gives these organisms not only an advantage in wood degradation processes, but seems rather to be a new evolutionatory alternative to enzymatic combustion.

Review on the current status of polymer degradation: a microbial approach
Vinay Mohan Pathak,Navneet +1 more
TL;DR: The occurrence and distribution of microbes that are involved in the degradation of both natural and synthetic polymers are described and it seems that biological agents and their metabolic enzymes can be exploited as a potent tool for polymer degradation.
Molecular characterization of dissolved organic matter (DOM): a critical review
TL;DR: Advances in water chemistry in the last decade have improved knowledge about the genesis, composition, and structure of dissolved organic matter, and its effect on the environment, and improved purification methods have enabled facile desalting and concentration of freshly collected DOM samples, thereby complementing the analytical process.

On the mechanism of enzymatic lignin breakdown
TL;DR: This paper proposes a mechanism which accounts for both the results obtained in enzymatic lignin degradation studies and in studies involving active oxygen species, and the implication of this type of mechanism on the oxidative biodegradation of the natural lign in polymer is discussed.

Isoenzymes of manganese-dependent peroxidase and laccase produced by the lignin-degrading basidiomycete Ceriporiopsis subvermispora.
TL;DR: The white-rot basidiomycete Ceriporiopsis subvermispora produces two families of ligninolytic enzymes, namely manganese-dependent peroxidases (MnPs) and laccases, when growing in liquid cultures of defined composition and the isoenzyme pattern of MnP is not altered throughout the growth period of the fungus.

TL;DR: Results suggest that the binding of veratryl alcohol to LiPIII* displaces O2-.

Production of Manganese Peroxidase and Organic Acids and Mineralization of 14C-Labelled Lignin (14C-DHP) during Solid-State Fermentation of Wheat Straw with the White Rot Fungus Nematoloma frowardii
Martin Hofrichter,Tamara Vares,Mika Kalsi,Sari Galkin,K. Scheibner,Wolfgang Fritsche,Annele Hatakka +6 more
TL;DR: It is concluded that at least partial extracellular mineralization of lignin may have occurred during solid-state fermentation of wheat straw using Nematoloma frowardiiproduced manganese peroxidase (MnP) as the predominant ligninolytic enzyme during SSF.

Bacterial degradation of lignin
TL;DR: The ability of bacteria to grow on low-molecular-weight lignin oligomers as the sole source of carbon and energy indicates that bacteria produce enzymes catalysing cleavage of intermonomeric linkages.
