  1. Andreina Traversa, Elisabetta Loffredo, Giancarlo Castellana, Nicola Senesi Dipartimento di Biologia e Chimica Agro-forestale e Ambientale, University of Bari Aldo Moro, Bari, Italy INTRODUCTION Bisphenol A (BPA) and 4-nonylphenol (NP) are two xenoestrogens able to disrupt the normal endocrine activity in animals and humans. BPA is used in the production of epoxy resins and polycarbonates, and as a stabilizer for plastics such as polyvinyl chloride, whereas NP is a component of nonylphenolpolyethoxilates which are a group of surfactants. Both compounds can contaminate the environment through the discharge or the application in agriculture of wastewaters, sewage sludges and other polluted matrices. Biodecontamination is a technology that utilizes the metabolic potential of microorganisms to remove pollutants in various environmental systems. • MATERIALS • FUNGI: Trametesversicolor(TRA), Stereumhirsutum(STE) and Pleurotusostreatus(PLE) • Sediments: collected from Sassano Lake (SL) and Morelli River (MR) OBJECTIVE To evaluate the potential capacity of three ligninolytic fungi to remove BPA and NP both at a concentration of 10 mg L-1 from a lake sediment and a river sediment collected in the Apulian region. Biodecontamination of sediments from the endocrine disruptors bisphenol A and 4-nonylphenol by ligninolytic fungi METHODS Sediments were contaminated with BPA and NP and not inoculated (controls) or inoculated with each fungus separately. After 7 days, the residual BPA and NP were extracted and quantified using HPLC analysis with fluorescence detection. All experimentswerereplicatedthreetimesand all data obtained were statistically analysed by ANOVA and the LSD test. RESULTS a b Bisphenol A (a)Residual BPA in SL sediment in the absence (control, C) and in the presence of each fungus. (b)Residual BPA in MR sediment in the absence (control, C) and in the presence of each fungus. (c)Residual NP in SL sediment in the absence (control, C) and in the presence of each fungus. (d) Residual NP in MR sediment in the absence (control, C) and in the presence of each fungus. The vertical line on each bar indicates the standard error for three replicates. d c Nonylphenol Tra: Trametes versicolor ;Ste: Stereum hirsutum;Ple: Pleurotus ostreatus In general, the three fungi were able to remove significant amounts of BPA and NP from both sediments. In SL sediment, the best decontamination effect was produced by TRA. In MR sediment, PLE resulted the most efficient fungus . REFERENCES Traversa A., Loffredo E., Gattullo C.E., Senesi N.
