摘要：

This paper describes the degradation of phenolic compounds by laccases from Trametes versicolor in an enzymatic membrane reactor (EMR). The enzymatic membranes were prepared by grafting laccase on a gelatine layer previously deposited onto a-alumina tubular membranes. The 2,6-dimethoxyphenol (DMP) was selected from among the three different phenolic compounds tested (guaiacol, 4-chlorophenol and DMP) to study the performance of the EMR in dead end configuration. At the lowest feed substrate concentration tested (100 mg.L-1), consumption increased with flux (up to 7.9 x 103 mg.h(-1).m(-2) at 128 L.h(-1).m(-2)), whereas at the highest substrate concentration (500 mg.L-1), it was shown that the reaction was limited by the oxygen content.
