Fig. 3From: Restriction-deficient mutants and marker-less genomic modification for metabolic engineering of the solvent producer Clostridium saccharobutylicumGrowth of C. saccharobutylicum Ch1 (a) and C. saccharobutylicum Ch1 ΔxylB (b) on different carbon sources. Cells were grown in 30 ml of MES-MM supplemented with 0.001% yeast extract and 40 g/l d-glucose (black circle), 40 g/l l-Arabinose (black square) or 40 g/l d-xylose (white up-pointing triangle)Back to article page
