#Corals and #sponges are hotspots of #ReactiveOxygenSpecies in the deep sea: Lina Taenzer et al. https://academic.oup.com/pnasnexus/article/2/11/pgad398/7420998

"authors took direct measurements of #superoxide in water closely surrounding corals, by bringing a one-of-a-kind deep-sea chemiluminescent sensor called SOLARIS, into the ocean over 2,000 meters deep, on board the #Alvin #submersible."

Deep sea sensor reveals that corals produce reactive oxygen species

Just like us, corals breathe in oxygen and eat organic carbon. And just like us, as a byproduct of converting energy and oxygen in the body, corals produce reactive oxygen species (ROS), a family of chemical compounds that are naturally made by cells during cell division, while fighting off pathogens, and performing other physiological functions.

Study: Visible light induces bacteria to produce superoxide for manganese oxidation

Manganese oxides are natural reactive minerals and widely spread in aquatic and terrestrial environments, affecting the fate of metals (such as As3+ and Cd2+) and organic pollutants (such as phenols and diclofenac) through adsorption and oxidation in sewage treatment. Usually, the manganese (III/IV) oxides in the environment are thought to be formed by the oxidation of dissolved Mn(II) through abiotic or biotic processes.
