Figure 4From: Metabolic engineering of Caldicellulosiruptor bescii yields increased hydrogen production from lignocellulosic biomassGrowth (O.D. 680 nm ) comparison of wild-type and mutant strains. (A) 0.5% of maltose and (B) 0.5% cellobiose as the carbon source; filled circles, Wild-type; open circles, ΔpyrFA (JWCB005); filled triangles, ΔpyrFA Δldh (JWCB017). Error bars based on three biologically independent experiments.Back to article page
