Deep Sea Bacteria Chemosynthesis

Deep Sea Bacteria Chemosynthesis-35
Cold seeps do not require high tectonic activity and may be located more sporadically across the deep sea.Again, specialized bacteria utilize the high density of sulfur or methane compounds to create food/energy, again forming the bottom of a complex food web.Detailed information on how Wiley uses cookies can be found in our Privacy Policy.

These bacteria convert the chemicals that shoot out of the hydrothermal vents into food for the worm.

Worldwide at the edges of tectonic plates Extremely deep, low energy, low nutrient waters in tectonically active areas Chemosynthetic bacteria, Giant Tube Worms, Deep-sea Mussels, Yeti Crabs Potential source of bio-products like medicines and other natural compounds Deep hydrothermal vents are like hot springs on the sea floor where mineral-rich, hot water flows into the otherwise cold, deep sea.

Minerals escaping from these vents usually include hydrogen sulfide or some other sulfur compound.

The deep-sea environment where these vents occur is completely dark, and photosynthesis (=the conversion of carbon dioxide into sugar using sunlight) is impossible.

The discovery of chemosynthetic ecosystems at deep-sea hydrothermal vents in 1977 changed our view of biology.

Chemosynthetic bacteria and archaea form the foundation of vent ecosystems by exploiting the chemical disequilibrium between reducing hydrothermal fluids and oxidizing seawater, harnessing this energy to fix inorganic carbon into biomass.

As these bacteria multiply, they form thick mats on which animals can graze.

In some cases, they form symbiotic relationships with animals, (e.g., giant tube worms) and live in the animals’ tissues, creating energy in return for receiving protection from predators.

This is Part 3 of a six-part series telling the story of humankind’s efforts to understand the origins of life by looking for it in extreme environments where life thrives without relying on the sun as an energy source.

It follows an oceanographic expedition to the Mid-Cayman Rise led by Chris German of the Woods Hole Oceanographic Institution, and NASA’s efforts to plan a future mission to Jupiter’s moon Europa.

    Deep sea bacteria have already solved the problem. Mussels Bathymodiolus puteoserpentis containing hydrogen-oxidizing symbionts have been identified and there is potential for scientist to be able to clone these hydrogen consuming bacteria to create all-natural hydrogen fuel cells.

    Deep-sea pelagic fish such as gulper eels have very large mouths, huge hinged jaws and large and expandable stomachs to engulf and process large quantities of scarce food. Many deep-sea pelagic fish have extremely long fang-like teeth that point inward. This ensures that any prey captured has little chance of escape.…

    Identifying bacteria that was responsible for the chemosynthesis process in areas such as oceanic hydrothermal vents has also led scientists to search for similar organisms in other well-known areas where sulfur is present in abundance, only to find similar connections between chemosynthetic bacteria and various other organisms, as in the case.…

    Since there is no light in the deep sea, deep-sea bacteria have to create energy using different sources. In a process called chemosynthesis, these chemoautotrophs combine the hydrogen sulfide that comes from the hydrothermal vents with hydrogen from water and oxidize it.…
