摘要

The production conditions, characteristics and dye decolourisation potentials of two purified bacterial laccases from Corynebacterium efficiens and Enterobacter ludwigii were investigated. Optimum production pH was 3.0 and 4.0 respectively for E. ludwigii and C. efficiens. Khaya sp. and Gmelina arborea wood shavings, (NH4)(2)SO4 (30.2 mu M/ml) and K+ maximally supported laccase production in both organisms. The Vmax and specificity constants for both purified laccases were 44.6 mu M/mg; 1858.4S(-1)mu M-1 and 23.15 mu M/mg; 1015.4S(-1)mu M-1 respectively. Maximum laccase activity was between 80 degrees C and 90 degrees C and pH 7.0. In both laccases, Fe3+ induced higher activity and red Dylon dye was 69% and 64% decolourised. The properties exhibited by these laccases could enhance their suitability in diverse biotechnological applications.
