The activities of Gldh and DhaK in cell-free extracts of recombinant Cb at 16, 36, and 48 h of growth. A Gldh specific activities, B Gldh % relative activities compared to wild-type Cp Gldh, C DhaK specific activities, D Gldh activity of Cb pWUR460_dhaD1 + gldA1 challenged with 4 g/L furfural. Different letters (e.g., a, b or c) indicate significance (p < 0.1) within each time point
