Genetic potential for aerobic respiration and #denitrification in globally distributed respiratory #endosymbionts https://www.nature.com/articles/s41467-024-54047-x
"They found a unique #bacterium that lives inside a ciliate (#protists) and provides it with energy... reminiscent of #mitochondria, with the key difference that the #endosymbiont derives energy from the respiration of nitrate, not oxygen."
