1,4-Dioxane is a probable human carcinogen and an
emerging water contaminant. Monooxygenase-expressing
bacteria have been shown to degrade dioxane via growth-
supporting as well as cometabolic mechanisms. In this study,
the intermediates of dioxane degradation by monooxyge-
nase-expressing bacteria were determined by triple
