Figure 4From: Elimination of hydrogenase active site assembly blocks H2 production and increases ethanol yield in Clostridium thermocellum Concentration of amino acids produced by wild-type, ΔhydG, and ∆hydG∆ech strains. *, asparagine quantification for two samples was prevented by interference. Error bars represent one standard deviation. Black bars, wild-type C. thermocellum; blue bars, C. thermocellum ∆hydG; red bars, C. thermocellum ∆hydG∆ech.Back to article page
