Simultaneous aerobic and anaerobic respiration in hot spring chemolithotrophic bacteria by Lisa M. Keller, Daniel R. Colman, Eric S. Boyd

“…Here we report a chemolithotrophic Aquificales bacterium, Hydrogenobacter, isolated from a circumneutral hot spring in Yellowstone National Park (YNP) capable of simultaneous aerobic and anaerobic respiration when provided with hydrogen (H2), elemental sulfur (S0), and O2. Cultivation experiments demonstrated that simultaneous aerobic and anaerobic respiration enhanced growth rates and final cell concentrations when compared to those grown aerobically or anaerobically. …”
