In the depths of the ocean, along tectonic plate boundaries, hydrothermal vents emit hot fluids. These fluids lack oxygen and are rich in metals like iron, manganese, and copper, as well as potentially carrying sulfides, methane, and hydrogen. As the hot water interacts with the cold, oxygen-rich se
Rising hundreds of meters from the seafloor and dispersing thousands of kilometers away from their origin, hydrothermal plumes might appear to be inhospitable environments. Yet, a study recently published inreveals that specific bacteria manage to thrive in these seemingly precarious locations.
in Bremen, Germany. These bacteria have so far only known to grow in low-oxygen environments, but gene sequences had occasionally also been detected in hydrothermal plumes. As their name suggests, they are known to use energy from sulfide. “We sampled plumes in extremely remote areas of ultraslow spreading ridges that were never studied before. Collecting hydrothermal plume samples is very complicated, as they are not easy to locate.
