The widespread agricultural application of carbofuran and concomitant contamination of surface and ground waters has raised health concerns due to the reported toxic effects of this insecticide and its degradation products. Most bacteria that degrade carbofuran only perform partial degradation involving carbamate hydrolysis without breakdown of the(More)
Carbofuran-mineralizing strain Novosphingobium sp. KN65.2 produces the CfdJ enzyme that converts the N-methylcarbamate insecticide to carbofuran phenol. Purified CfdJ shows a remarkably low KM towards carbofuran. Together with the carbaryl hydrolase CehA of Rhizobium sp. strain AC100, CfdJ represents a new protein family with several uncharacterized(More)
Complete mineralization of the N-methylcarbamate insecticide carbofuran, including mineralization of the aromatic moiety, appears to be confined to sphingomonad isolates. Here, we report the first draft genome sequence of such a sphingomonad strain, i.e., Novosphingobium sp. KN65.2, isolated from carbofuran-exposed agricultural soil in Vietnam.
