BackgroundIn the biorefinery utilizing lignocellulosic biomasses, lignin decomposition to value-added phenolic derivatives is a key issue, and recently biocatalytic delignification is emerging owing to its superior selectivity, low energy consumption, and unparalleled sustainability. However, besides heme-containing peroxidases and laccases, information about lignolytic biocatalysts is still limited till date.ResultsHerein, we report a promiscuous activity of tyrosinase which is closely… 

In silico exploration of lignin peroxidase for unraveling the degradation mechanism employing lignin model compounds

TLDR
It is demonstrated that bacterial LiP can effectively catalyze multiple lignin model compounds, and it might further be used as an effective tool for sustainable mitigation of diverse environmental contaminants.

A multi-omics approach to lignocellulolytic enzyme discovery reveals a new ligninase activity from Parascedosporium putredinis NO1

TLDR
An oxidase activity is described that cleaves the major β-ether units in lignin, thereby releasing the flavonoid tricin from monocot lignIn and enhancing the digestion of lignocellulose by polysaccharidase mixtures.

Hemocyanin facilitates lignocellulose digestion by wood-boring marine crustaceans

TLDR
Evidence is provided that the woodborer’s respiratory protein hemocyanin plays a central role in wood digestion and may offer a route toward biorefining of woody plant biomass.

Development of a magnetically separable co-immobilized laccase and versatile peroxidase system for the conversion of lignocellulosic biomass to vanillin

TLDR
The lignocellulosic content of the Casuarina biomass is exploited to extract the lignin, which provides a renewable alternative for the production of the commercially high-valued compound, vanillin.

Functionalized Tyrosinase-Lignin Nanoparticles as Sustainable Catalysts for the Oxidation of Phenols

TLDR
Sustainable catalysts for the oxidation of phenol derivatives under environmentally friendly conditions were prepared by the functionalization of lignin nanoparticles with tyrosinase, with the efficacy of the catalyst being dependent on the specific immobilization procedures.

A gene deletion strain of R. jostii RHA1 in which the vanillin dehydrogenase gene had been deleted, was found to accumulate vanillin with yields of up to 96 mg/L after 144 h, together with smaller amounts of ferulic acid and 4-hydroxybenzaldehyde.

Spectroscopic evidence for an engineered, catalytically active Trp radical that creates the unique reactivity of lignin peroxidase

TLDR
This work shows that it is necessary to take into account the physicochemical properties of the radical, fine-tuned by the microenvironment, as well as those of the preceding [Fe(IV)=O Por•+] intermediate to engineer a catalytically competent Trp site for a given substrate.
