Production of CtDH/CtCDHs expressed in E. coli (a), A. niger (b) and T. reesei (c). Purple circles wet biomass; red triangles volumetric activity (DCIP assay at acetate buffer pH 5.5), green diamonds volumetric activity (cyt c assay in Tris/HCl buffer, pH 7.5), blue squares protein concentration (per broth volume), dark yellow circles glucose concentration of fermentation broth. The measurements were done in triplicates; the difference between the values was less than 5%
