Life in extreme environments: Hydrothermal vents PNAS

The most abundant bacteria in hydrothermal vents are chemolithotrophs. These bacteria use reduced chemical species, most often sulfur, as sources of energy to reduce carbon dioxide to organic carbon. The chemolithotrophic abundance in a hydrothermal vent environment is determined by the available energy sources; different temperature vents have different concentrations of nutrients, suggesting large variation between vents. In general, large microbia… Web17 aug. 2024 · Another example of chemosynthesis was discovered in 2013 when bacteria were found living in basalt below the sediment of the ocean floor. These bacteria were not associated with a hydrothermal vent. It has been suggested the bacteria use hydrogen from the reduction of minerals in seawater bathing the rock.
