Method "G. metallireducens dcuB strain was grown in batch using acetate/fumarate medium and also in a chemostat at a set growth rate (Table 3). The growth rate determined in this study was similar to that previously reported (0.114/hr vs 0.105/hr, respectively) [26]. From these two conditions, it was possible to estimate the maintenance costs (GAM and NGAM) for the model using an established procedure [9,18]. The calculated costs were 79.20 mmol ATP/gDW for the GAM and 0.81 mmol ATP/(gDW×hr) for the NGAM."
Comments "These values are similar to those found previously for G. sulfurreducens [12], thus it provided confidence in the use of the GAM and NGAM throughout the study. The additional content included in the ETS [electron transport system] was further analyzed using experimental data."
