The evaluation of continuous elimination and transformation of toxic endocrine disruptors micropollutants (MPs) (Bisphenol A, Nonylphenol [NP] and Triclosan [TCS]) using immobilized laccase of Coriolopsis sp. showed the high potential of this laccase as a bio-agent for the elimination and transformation process of selected MPs. A toxicology test using Escherichia coli has shown that toxicity completely disappeared after transformation and elimination of Bisphenol A, while in cases of NP and TCS 95% and 90% toxicity, respectively, disappeared. As compared to initial activity, immobilized laccase activity remained practically constant at the end of several runs of elimination and transformation processes of MPs. This feature is promising for the use of immobilized Coriolopsis sp. laccase in a future industrial depollution process.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
