Do Chemosynthetic Bacteria Need Oxygen?

Do Chemosynthetic Bacteria Need Oxygen? Like photosynthetic bacteria, chemosynthetic bacteria need a carbon source (e.g. carbon dioxide) as well as an energy source in order to manufacture their own food. For the most part, these bacteria are aerobic and therefore rely on oxygen to complete this process successfully. Is chemosynthesis aerobic or anaerobic? Chemosynthesis (aerobic)
