Figure 7From: A genome-guided analysis of energy conservation in the thermophilic, cytochrome-free acetogenic bacterium Thermoanaerobacter kivuiModel of electron and carbon flow in T. kivui when growing autotrophically. Fdred, reduced ferredoxin; a H+/ATP ratio of 12/3 was assumed for the F1FO ATP synthase. *, reduction of methylene-THF might occur using an electron donor with a similar redox potential as NADH. CoFeSP, corrinoid/FeS protein.Back to article page
