No full textBisphenol A (BPA) is an endocrine disruptor compound (EDC) of xenobiotic origin occurring in natural
waters and wastewaters, especially in the most industrialized and urbanized areas. Recent investigations
report the use of ligninolytic fungi for the removal of aromatic contaminants, including some
EDCs, from different matrices. Humic acids (HA) are widely spread in all natural systems and their
presence is ascertained to interfere with microbial growth and activity. The objective of this study was
to assess the capacity of three ligninolytic fungi, Trametes versicolor, Stereum hirsutum and Pleurotus
ostreatus, to remove BPA at the concentration of 4.6 mg L1 from water. Fungal growth on potato
dextrose agar (PDA), in the absence and in the presence of a leonardite HA or a green compost HA, was
evaluated during the biodecontamination process. The methodological approach adopted in this study
excluded the presence of the mycelium in the contaminated water. Results obtained evidenced a
relevant removal of BPA by any fungus when PDA only was used as growing medium. The addition of
leonardite HA and compost HA stimulated the mycelial growth of any fungus, especially T. versicolor,
and significantly enhanced the removal of the contaminant from water by, respectively, T. versicolor
only and T. versicolor and S. hirsutum
