Figure 4From: Improving the functional expression of a Bacillus licheniformislaccase by random and site-directed mutagenesisDecolorization of different industrial dyes. Decolorization catalyzed by wild-type CotA and CotA mutants was investigated in the absence (dark gray bars) and presence (light gray bars) of the redox mediator violuric acid after 5 min, 30 min, and 60 min of reaction. A) Decolorization of alizarin red S; B) decolorization of remazol brilliant blue R; C) decolorization of indigo carmine.Back to article page
