  1. In addition, the ATPmaint coefficient calculated from the respective experiment is shown. The yields refer to the used substrate (in case of CO2 + H2, the yield refers to CO2). Note that the maximum biomass yields (model and experimental) refer to the (true) biomass yields, i.e., substrate consumption required for ATP maintenance is excluded when calculating the yield
