From: Enhanced ethanol formation by Clostridium thermocellum via pyruvate decarboxylase
Two ethanol production pathways from pyruvate. PFOR pyruvate ferredoxin oxidoreductase, ALDH acetaldehyde dehydrogenase, ADH alcohol dehydrogenase, PDC pyruvate decarboxylase, FNOR ferredoxin-NAD(P)+ oxidoreductase, Fdo oxidized ferredoxin, FdR reduced ferredoxin. All the ΔrG′m values were calculated by eQuilibrator [51] and are in units of kJ/mol. ‘m’ to mark the 1 mM concentration that is used for all reactants. For purposes of calculation, CO2 is assumed to be in the gas phase
