Actvity Summary: This poster highlights fun facts about this hydrothermal-chimney-lovin' microbe!


In the deep subsurface, oxygen is limited (or even completely absent), and is often toxic to many microbes living there. What do microbes “breathe” then? Microbes can use a multitude of chemicals (from iron to methane, hydrogen or sulfur) to get their energy through the transfer of electrons, a process call reduction-oxidation, or redox. Caldithrix abyssi can reduce nitrate into ammonium in a similar way we reduce oxygen to make carbon dioxide.
