Chemosynthesis | Definition of Chemosynthesis by Merriam-Webster

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. The bacteria could react hydrogen and carbon dioxide to produce methane.

The word "chemosynthesis" was originally coined by Wilhelm Pfeffer in 1897 to describe energy production by oxidation of inorganic molecules by autotrophs (chemolithoautotrophy). Under the modern definition, chemosynthesis also describes energy production via chemoorganoautotrophy.

A typical picture of an active hydrothermal vent is therefore one with shimmering warm hydrothermal fluids, tubeworms and many other vent species, all densely clustered around the vent, with white microbial mat material covering the surrounding area.


What organisms perform chemosynthesis and why? | Yahoo Answers

The answer came from the discovery that bacteria in the vents were able to convert hydrogen sulfide coming out of the vents into energy. These bacteria then supported large tube worms, crustaceans, and multitudes of other organisms.

Deep Sea vents: Chemosynthesis, the basis of life in the deep sea
A remarkable find when submersables starting probing the deep sea was the presence of extraordinary abundance of life around mid-ocean vents. Previously, scientists believed that little lived at these emense depths. The only food that would have been avaliable was through dead animals floating down from the surface waters. So what was this abundance sustaining itself on?

What is Chemosynthesis? | Yahoo Answers

The idea that microorganisms could live on inorganic compounds was proposed by Sergei Nikolaevich Vinogradnsii (Winogradsky) in 1890, based on research conducted on bacteria which appeared to live from nitrogen, iron, or sulfur. The hypothesis was validated in 1977 when the deep sea submersible Alvin observed tube worms and other life surrounding hydrothermal vents at the Galapagos Rift. Harvard student Colleen Cavanaugh proposed and later confirmed the tube worms survived because of their relationship with chemosynthetic bacteria. The official discovery of chemosynthesis is credited to Cavanaugh.

chemosynthesis | LexRoll Dictionary

Chemosynthesis has been detected in hydrothermal vents, isolated caves, methane clathrates, whale falls, and cold seeps. It has been hypothesized the process may permit life below the surface of Mars and Jupiter's moon Europa. as well as other places in the solar system. Chemosynthesis can occur in the presences of oxygen, but it is not required.

name two types of bacteria that perform chemosynthesis

Chemosynthesis is the conversion of carbon compounds and other molecules . In this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, to act as the energy source. In contrast, the energy source (the set of reactions through which carbon dioxide and water are converted into glucose and oxygen) uses energy from sunlight to power the process.
