Chemosynthesis Organisms Found

There are generally three kinds of vents that occur and are all characterized by its temperature and chemical composition.

Diffuse vents release clear water typically up to 30 °C.

The organisms utilize the minerals and chemicals that come out of the vents.

Extreme conditions in the hydrothermal vent environment means that microbial communities that inhabit these areas need to adapt to them.

Microbes that live here are known to be hyperthermophiles which by definition are microorganisms that grow at temperatures above 90 °C.

These organisms are found where the fluids from the vents are expelled and mixed with the surrounding water.White smoker vents emit a milky coloured water that are approximately 200-330 °C, black smoker vents generally release water hotter than the others between 300-400 °C.The waters from black smokers are darkened by the precipitates of sulfide that are accumulated.It was first discovered in 1890 by Sergei Nikolaevich Vinogradskii as a result of his physiological research in that period.The existence of chemosynthesis was confirmed about 90 years later with the discovery of deep sea hydrothermal vents.These hyperthermophilic microbes are thought to contain proteins that have extended stability at higher temperatures due to intramolecular interactions but the exact mechanisms are not clear yet.The stabilization mechanisms for DNA are not as unknown and the denaturation of DNA are thought to be minimized through high salt concentrations, more specifically Mg, K, and PO4 which are highly concentrated in hyperthermophiles.This allows water from the ocean to enter into the crust of the earth where it is heated by the magma.The increasing pressure and temperature forces the water back out of these openings, on the way out, the water accumulates dissolved minerals and chemicals from the rocks that it encounters.These organisms also provide the foundation for further development of the ecosystem as they are hunted by larger creatures.The Hydrothermal vent microbial community encompasses all unicellular organisms that live and reproduce in a chemically distinct area around Hydrothermal vents.

    Chemosynthesis is a process of producing energy by burning chemicals. It requires no sunlight and is typical for deep sea ecosystems near the hydrothermal vents. It was first discovered in 1890 by Sergei Nikolaevich Vinogradskii as a result of his physiological research in that period.…

    Hydrothermal vents have been found all over the ocean, including regions of the Pacific, Atlantic, Indian, Southern and Arctic oceans. The deepest vent located so far is in the Cayman Trough, which is the deepest point in the Caribbean Sea. The trough is located along the boundary between the North American Plate and the Caribbean Plate.…

    This process is called chemosynthesis, and is carried out by microorganisms in the rocks, sediments, fluids, and even within some of the animals found at hydrothermal vents. Figure 1 This image traces the pathway that seawater makes through the ocean crust as it is chemically and thermally transformed into hydrothermal fluid.…

    Algae are eukaryotic organisms that have characteristics of both plants and animals. Like animals, algae are capable of feeding on organic material in their environment. Some algae also contain organelles and structures found in animals cells, such as flagella and centrioles. Like plants, algae contain photosynthetic organelles called chloroplasts.…

    The bacteria found in hydrothermal vents undergo chemosynthesis. That is, they break down chemicals to generate their own food, just as a plant would undergo photosynthesis. Why do deep sea.…

    Huge red-tipped tube worms, ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme deep ocean ecosystems found near undersea volcanic chains. How is life possible here? In a process called chemosynthesis, microbes at the base of the foodchain convert chemicals from the vents into usable energy.…

    Microbes are also found to be in symbiotic relationships with other organisms in the hydrothermal vent environment due to their ability to have a detoxification mechanism which allows them to metabolize the sulfide-rich waters which would otherwise be toxic to the organisms and the microbes.…

    Chemosynthesis. Chemosynthetic microbes provide the foundation for biological colonization of vents. Chemosynthetic microbes live on or below the seafloor, and even within the bodies of other vent animals as symbionts. Where microbial mat covers the seafloor around vents, grazers such as snails, limpets, and scaleworms eat the mat.…
