Polymerization of Phenolic Compounds by a Soil-Enzyme Complex¹

ABSTRACT

Phenolic substrates representing lignin or xenobiotic model compounds were incubated with a phenoloxidase-like catalyst extracted from soil. The resulting oxidative products were separated by thin-layer chromatography and characterized by mass spectrometry. The soil-enzyme complex transformed guaiacol, 1-naphthol, and 4-chloro-l-naphthol into oligomeric products by carbon-to-carbon and carbon-to-oxygen coupling reactions. Heat inactivated soil extract controls showed no ability to polymerize the various substrates. These results support the view that biosynthetic reactions, exemplified by the oxidative coupling of phenols, affect the fate of various chemicals introduced to the environment.
