Production of Specifically Labeled Compounds by Methanobacterium espanolae Grown on H(2)-CO(2) plus [C]Acetate.

abstract：:1-Hydroxybenzotriazole, violuric acid, and N-hydroxyacetanilide are three N-OH compounds capable of mediating a range of laccase-catalyzed biotransformations, such as paper pulp delignification and degradation of polycyclic hydrocarbons. The mechanism of their enzymatic oxidation was studied with seven fungal laccases...
