title: Potentialities of a membrane reactor with laccase grafted membranes for the enzymatic degradation of phenolic compounds in water.
abstract: 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 α-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 × 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.
