Résumé
Oxidation of phenolic compounds is an urgent need in textile industry, biological refinements, pulp and paper production. In present study, a laccase was purified from symbiotic bacterium of Bacillus sp. CF96 existing in termite digestive system. The extracellular laccase was purified via amnion sulfate precipitation, membrane dialysis, and ion exchange chromatography. The results showed that the Bacillus CF96 laccase possesses a molecular mass of 63 kDa, an optimal pH and temperature of 8.0 and 60 °C. Results showed that Zn
