title: Biotransformation of fluorene, diphenyl ether, dibenzo-p-dioxin and carbazole by Janibacter sp.
abstract: Fluorene, diphenyl ether, dibenzo-p-dioxin, and carbazole were used by a dibenzofuran-utilizing Janibacter sp. strain YY-1. Metabolites were identified by GC-MS. Angular dioxygenation was the major pathway for degradation of fluorene, diphenyl ether, and dibenzo-p-dioxin but not for carbazole. Lateral dioxygenation of all tested compounds was indicated by the detection of mono- or di-hydroxylated compounds. The bacterium also catalyzed the monooxygenation of fluorene at the C9 position.
