Figure 4From: Assessment of metabolic flux distribution in the thermophilic hydrogen producer Caloramator celer as affected by external pH and hydrogen partial pressure Correlation between distribution of fluxes at the pyruvate node and growth rate, H 2 yield and pyruvate flux. Correlation between formate flux (v14) and growth rate (A) in exponential phase (circles), transition phase (diamonds) and stationary phase (squares) at pHÂ 7 with N2 sparging (Case I, black) and without N2 sparging (Case II, dark grey), and at pHÂ 6 with N2 sparging (Case III, light grey) and without N2 sparging (Case IV, white). Correlation between fraction of flux through PFOR during exponential phase and pyruvate flux during exponential phase (open symbols), and overall H2 yield (filled symbols) (B) at pHÂ 7 with N2 sparging (Case I, diamonds) and without N2 sparging (Case II, triangles), and at pHÂ 6 with N2 sparging (Case III, circles) and without N2 sparging (Case IV, squares).Back to article page
