Özet

Bacterial laccases are very stable at high temperature and high pH values, and have many biotechnological and industrial applications. Here we describe how we cloned, expressed and purified the laccase fromBacillus subtilis(B. subtilis).The enzyme molecular weight has been determined as 34 kDa in SDS- PAGE analysis. The activity of the recombinant enzyme has been proved by guaiacol oxidation. TheK(M)andV(max)values of the enzyme were at 1.1077 mM and at 19.3 mu mol/min/mg, respectively. The recombinant laccase was effective in the decolorization of Turquoise blue HF6, Remazol red 106, Remazol brilliant orange 3R, and Brilliant blue, thus, possessing the characteristics necessary for its possible application in textile and environmental industries.
