Web11 dec. 1992 · A search for high-temperature activity of sulfate-reducing bacteria was done in hot deep-sea sediments at the hydrothermal vents of the Guaymas Basin tectonic spreading center in the Gulf of California. Radiotracer studies revealed that sulfate reduction can occur at temperatures up to 110°C, with an optimum rate at 103° to 106°C. Web2 dagen geleden · Extreme Vents. Hydrothermal vents are considered ‘extreme’ habitats for life for a number of reasons. Because some of the vent locations are deep below water, the pressure can be extremely high. When human divers swim to great depths, they must be extremely careful because high pressures can have life-threatening consequences.
