Tannins are secondary metabolites that enriched in the bark, roots, and knots trees known to hinder microbial attack. The biological degradation of water-soluble gallotannins, such as tannic acid, is initiated by tannase enzymes (EC 3.1.1.20), which esterases able liberate gallic acid from aromatic-sugar complexes. However, only few tannases have previously been studied detail. Here, for first time, we biochemically structurally characterize three a single organism, anaerobic bacterium...
The bark is the outermost defense of trees against microbial attack, largely thanks to toxicity and prevalence extractive compounds. Nevertheless, decomposes in nature, though by which species mechanisms remains unknown. Here, we have followed development enrichments growing on spruce over six months, monitoring both chemical changes material performing community metagenomic analyses. Carbohydrate metabolism was unexpectedly limited, instead a key activity extractives. Resin acid degradation...
Together with bacteria and filamentous fungi, yeasts actively take part in the global carbon cycle. Over 100 yeast species have been shown to grow on major plant polysaccharide xylan, which requires an arsenal of carbohydrate active enzymes. However, enzymatic strategies use deconstruct xylan what specific biological roles they play its conversion remain unclear. In fact, genome analyses reveal that many xylan-metabolizing lack expected xylanolytic Guided by bioinformatics, we here selected...
The bark represents the outer protective layer of trees. It contains high concentrations antimicrobial extractives, in addition to regular wood polymers. a huge underutilized side stream forestry, but biotechnological valorization is hampered by lack knowledge on microbial degradation. Many fungi are efficient lignocellulose degraders, and here, spruce degradation five species, Dichomitus squalens, Rhodonia placenta, Penicillium crustosum, Trichoderma sp. B1, reesei, was mapped, continuously...

Summary Together with bacteria and fungi, yeasts actively take part in the global carbon cycle. Over a hundred yeast species have been shown to grow on major plant polysaccharide xylan, which requires an arsenal of carbohydrate active enzymes. However, enzymatic strategies use deconstruct xylan what specific biological roles they play its conversion remain unclear. In fact, genome analyses reveal that many xylan-metabolizing lack expected xylanolytic Guided by bioinformatics, we here...
