Bisphenol F (BPF) consists of two phenolic rings joined together through a bridging carbon. It belongs to the bisphenol group which are important raw materials used in the production of polycarbonate and epoxy resins. Considerable amounts of bisphenols have been discharged into a broad range of aquatic and terrestrial environments as a result of its widespread use.

Sphingobium yanoikuyae strain FM-2 can degrade BPF by attack on the bridging carbon, forming first the alcohol and then the ketone. Next Baeyer-Villiger oxidation forms 4-hydroxyphenyl 4-hydroxybenzoate, which is hydrolyzed to form 4-hydroxybenzoate and 1,4-hydroquinone (Inoue et al., 2008).

The following is a text-format Bisphenol F pathway map. An organism which can initiate the pathway is given, but other organisms may also carry out later steps. Follow the links for more information on compounds or reactions. This map is also available in graphic (10k) format.
