Phenol Removal by Peroxidases exrracted from Chinese Cabbage Root

Abstract

|
|
Solid and liquid phase peroxidases were extracted from Chinese cabbage roots by using commercial juicer in order to use peroxidases from agricultural waste for industrial applications. Since peroxidases are distributed into 66 % in liquid (juice) and 34 % in solid phase (pulp), enzymes from both phases were applied to investigate the enzymatic removal of phenol from waste water. After contacting 150 ppm phenol solution with liquid phase enzyme (1,800 unit/h ) for 3 hours in a batch stirred reacto;96
of phenol could be removed through polymerization and precipitation. Also, phenol could be removed from initial 120ppm to 5ppm by applying solid phase enzyme in an air lift reactor (600 unit/& ). Almost equivalent efficiencies of phenol removal were observed between two systems, eventhough only one third of the enzymes in batch stirred reactor was applied in air lift reactor. The possible reason for this phenomenon is because peroxidases exist as immobilized forms in solid phase.
