Biodegradation of bisphenol A and bisphenol F in the rhizosphere sediment of Phragmites australis

The accelerated removal of bisphenols A and F (BPA, BPF) was observed in the rhizosphere sediment of Phragmites australis, while they persisted in the absence of P. australis. A BPA-degrading bacterium, Novosphingobium sp. strain TYA-1, and a BPF-degrading bacterium, Sphingobium yanoikuyae strain TYF-1, were isolated from the rhizosphere of P. australis. The results suggested that interactions between P. australis and these bacteria can accelerate the removal of bisphenols from sediment. (C) 2009, The Society for Biotechnology, Japan.
