Fig 3.

Substrate consumption/product formation during growth of A. fulgidus on 12 mM 2‐methoxyphenol versus 34 mM lactate. Values refer to mmol per culture. Red values are based on experimental measurements (see Fig. 2; dark red values refer to resting cell experiment) and blue values are based on estimations (Compensation for the experimentally determined values for metabolites such as CO₂ and MP). Dark green dotted arrows visualize electrons liberated during carbon metabolism that are consumed during sulfate reduction. Sulfide is most likely underestimated as sulfide reacts with other medium/cell components and is also used for assimilation. [Color figure can be viewed at wileyonlinelibrary.com]
