Oxidation of flame retardant Tetrabromobisphenol A by a biocatalytic nanofiber of chloroperoxidase

摘要: Background: Tetrabromobisphenol (TBBPA), a flame retardant compound, is considered ubiquitous pollutant, with potential impact on the environment and human health. Several technologies have been applied to accelerate its degradation minimize environmental impacts. Due aromaticity character, peroxidase enzymes may be employed carry out transformation in mild conditions. Therefore, purpose of this work was determine capacity enzyme chloroperoxidase (CPO) oxidize TBBPA several water samples. Methods: The oxidation CPO evaluated catalytic conditions using samples from surface groundwater, as well effluents wastewater treatment plants. biocatalytic performance improved due immobilization nanofibers composed polyvinyl alcohol chitosan (PVA/chitosan). Results: Free immobilized were able transform more than 80% short reaction times (60 min); producing biodegradable less toxic products. Particularly, catalytically active wider range pH free possibility reusing it up five times. Conclusions: under highly efficient, even complex media such treated
