Figure 3From: A genome-guided analysis of energy conservation in the thermophilic, cytochrome-free acetogenic bacterium Thermoanaerobacter kivuiEffect of Na+on autotrophic growth of T. kivui . Cultures grown on H2 + CO2 were transferred into Na+-enriched (●) and Na+-deficient (○) minimal medium. The curves shown are representative for three independent experiments. Precultures were grown for four transfers in the same medium.Back to article page
