Comparison of marker gene expression and cellulose production between recombinant laccase producing and parental strains. A. Log2 ratios of gene expression between recombinant and parental strains in chemostat cultures (D = 0.03 h-1). Error bars indicate the standard deviation between triplicate cultures. Genes showing higher expression ratios than 1.5-fold are marked as green (higher in recombinant strain) or red (higher in parental strain) B. Comparison of specific production levels (nKat mg-1 DW) of three secreted hydrolases (CBH, EG and BGL) between parental (red) and recombinant (green) strains.
