Elimination of Bisphenol A and Triclosan Using the Enzymatic System of Autochthonous Colombian Forest Fungi

Table 4

Acute toxicity of the untreated and treated solutions containing initially 5 mg L−1 of BPA and TCS by using D. pulex. The enzymatic treatments occur for 6 hours at a pH of 5 and a temperature of 60°C using 250 U L−1 of laccase activity.
