چکیده    Background: elimination of hazardous phenolic compounds using laccases has gained attention during recentdecades. the present study was designed to evaluate the ability of the purified laccase from paraconiothyriumvariabile (pvl) for elimination of phenol and the endocrine disrupting chemical bisphenol a. effect of laccaseactivity, ph, and temperature on the enzymatic removal of the mentioned pollutants were also investigated.results: after 30 min treatment of the applied phenolic pollutants in the presence of pvl (5 u/ml), 80% of phenoland 59.7% of bisphenol a was removed. increasing of laccase activity enhanced the removal percentage of bothpollutants. the acidic ph of 5 was found to be the best ph for elimination of both phenol and bisphenol a.increasing of reaction temperature up to 50°c enhanced the removal percentage of phenol and bisphenol a to96.3% and 88.3%, respectively.conclusions: to sum up, the present work introduced the purified laccase of p. variabile as an efficient biocatalystfor removal of one of the most hazardous endocrine disruptor bisphenol a.
