Figure 3From: Increasing the metabolic capacity of Escherichia coli for hydrogen production through heterologous expression of the Ralstonia eutropha SH operonGrowth and in vivo hydrogen production by strains expressing SH hydrogenase. Cultures, pregrown under the same conditions, were incubated at 37°C in anaerobic vials containing modified M9 glucose (+IPTG, Ni and Fe). Samples were taken periodically to measure OD (A) and hydrogen (B). FTGH2/pJWPH5 (-♦-); FTJWDC3/pJWPH5 (-■-); JWGH1/pJWPH5 (-△-); DJ1/pJWPH5 (-○-); DG2/ pJWPH5 (-□-); FTDPH10/ pJWPH5 (-●-).Back to article page
