Giant deep-sea vent tubeworm symbionts use two carbon fixation pathways to grow at record speeds
https://phys.org/news/2024-06-giant-deep-sea-vent-tubeworm.html
In the deep-sea environment of the East Pacific Rise, where sunlight does not penetrate and the surroundings are known for their extreme temperatures, skull-crushing pressures, and toxic compounds, lives Riftia pachyptila, a giant hydrothermal vent tubeworm. Growing up to 6 feet tall with a deep-red plume, Riftia does not have a digestive system but thrives off its symbiotic relationship with bacteria that live deep within its body. These billions of bacteria fix carbon dioxide to sugars to sustain themselves and the tubeworm.
