[Conversion of polychlorophenols by laccases with 1-hydroxybenzotriazole as a mediator].
The action of purified laccase from the basidial fungi Cerrena unicolor and Trametes sp. on 2,4,6-trichlorophenol (2,4,6-TCP) and pentachlorophenol (PCP) was studied, including reactions involving I-hydroxybenzotriazole as a mediator. Oxidation of 2,4,6-TCP by laccase without the mediator yielded 2,6-dichlorobenzoquinone as a primary conversion product, whereas PCP was not oxidized. Products of further conversion of 2,4,6-TCP and PCP formed with the presence of the mediator.
