Isolation and characterisation of a Sphingomonas strain able to degrade the fungicide ortho-phenylphenol.

Background: Ortho-phenylphenol (OPP) is a fungicide used in fruit packaging plants for the control of fungal infestations during storage. Its application leads to the production of large wastewater volumes which according to the European legislation should be treated on site. In spite of this, no efficient treatment systems are currently available, and the development of biological systems based on tailored-made pesticide-degrading inocula for the treatment of these wastewaters is an appealing solution.
