The effect of the additive, polyethylene glycol 4000 (PEG), on the laccase-catalyzed removal of 2,4-dichlorophenol (DCP) from synthetic wastewaters was studied over the DCP concentration range 2-16 mM. Results showed that PEG had a significant protective effect on laccase activity. The amount of enzyme required to obtain 50% pollutant removal was reduced 35-, 39- and 20-fold less than that required without PEG for 4, 8 and 16 mM DCP solutions, respectively.

Abstract
The effect of the additive, polyethylene glycol 4000 (PEG), on the laccase-catalyzed removal of 2,4-dichlorophenol (DCP) from synthetic wastewaters was studied over the DCP concentration range 2-16 mM. Results showed that PEG had a significant protective effect on laccase activity. The amount of enzyme required to obtain 50% pollutant removal was reduced 35-, 39- and 20-fold less than that required without PEG for 4, 8 and 16 mM DCP solutions, respectively.File in questo prodotto:
