Abstract

The fungus Rhizoctonia praticola produces an extracellular phenol oxidase (laccase) which polymerizes phenolic intermediates of various pesticides. The enzyme catalyzes the formation of oligomeric products from halogenated phenolic intermediates of phenoxyalkanoate herbicides and from naphtholic products derived from carbamate insecticides. These findings permit further investigations into the mechanism and role of oxidative coupling leading to the incorporation of xenobiotic compounds into soil organic matter.

摘要

真菌立枯丝核菌产生一种细胞外酚氧化酶（漆酶），该酶可使各种农药的酚类中间体聚合。这种酶催化苯氧链烷酸酯类除草剂的卤代酚中间体以及氨基甲酸酯类杀虫剂衍生的萘酚产物形成低聚产物。这些发现有助于进一步研究氧化偶联的机制和作用，氧化偶联导致异源生物化合物掺入土壤有机质中。
