BIODEGRADATION OF BISPHENOL A DURING SUBMERGED CULTIVATION OF TRAMETES VERSICOLOR

Abstract

Bisphenol A is a persistent chemical, which is widely distributed in the environment despite its short half-life. The continuous release of BPA may cause a chronical exposition of the organisms during sensitive life stages. The chemical possesses not only endocrine disrupting functions but also by oxidative stress may cause damage to the liver cells. In this study the ability of Trametes versicolor 8979 to degrade Bisphenol A during submerged cultivation was exanimated. The chemical was introduced to the medium in 500ppm concentration and the laccase and MnP activities, as well as the residual BPA concentration were monitored. The strain was able to remove completely Bisphenol A from the medium in 6 hours.
