Table 4 Theoretical ranges of hydrogen yields for photoheterotrophic growth on different substrates and with different genetic modifications.

From: Metabolic network modeling of redox balancing and biohydrogen production in purple nonsulfur bacteria

Substrate ΔRubisco ΔRubisco, +oxPPP/+oxTCA max YH2
Succinate 1.38 1.38 - 7 7 (1.75)
Malate 0.38 0.38 - 6 6 (1.5)
Propionate 1.38 1.38 - 7 7 (2.33)
Fructose 0.75 0.75 - 12 12 (2)
Acetate (Glyox) 0.51 - 4 0.51 - 4 4 (2)
Acetate (EMCoA) 0-4 0-4 4 (2)
  1. ΔRubisco: RubisCO knockout, +oxPPP/+oxTCA: activated oxidative pentose phosphate pathway/activated oxidative TCA. Yields are given as mole hydrogen per mole substrate, yields in parentheses (last column) are given as mole hydrogen per mole carbon.
