Biodegradation of brominated aromatics by cultures and laccase of Trametes versicolor

Original language description

2-Bromophenol (1), 4-bromophenol (2), 2,4-dibromophenol (3), 2,6-dibromophenol (4), 2,4,6-tribromophenol (5) and tetrabromobis phenol A (6) (1 mM each) added to growing submerged cultures of Trametes versicolor CCBAS 612 were eliminated by 65-85% from the culture medium within 4 d. Extracellular laccase activity in the culture medium was influenced by the type of brominated compound added. Maximum level of laccase (63 U L-1) was found in the culture with 2-bromophenol. Tetrabromobisphenol A was degradedby a commercial laccase from Trametes versicolor in absence of any oxidation mediator, hydroxylated dibrominated compounds being detected as soluble reaction products by LC/MS. A significant degradation of brominated phenols by laccase was achieved onlyin the presence of ABTS structural characterization of major products suggesting reaction between bromophenol and ABTS radicals.
