Abstract

A laccase produced the Trametes sp. was immobilized on CNBr-activated Sepharose 4B(CS4B) and tested for repeated-batch and continuous decolorization of dye. After immobilization, the enzyme was active in wider pH and temperature range, and its heat stability was greatly improved compared to those of the free laccase. Immobilized laccase was efficient for both repeated-batch and contionuous decolorization.
