Word of the day: Chemosynthesis

https://en.wikipedia.org/wiki/Chemosynthesis

To think that this process may be enabling life on other worlds is inspiring.

Chemosynthesis - Wikipedia

#KnowledgeByte: #Chemosynthesis is a process by which certain organisms, primarily bacteria, use chemical energy to produce organic matter from inorganic substances.

Unlike #Photosynthesis, which uses sunlight as an energy source, chemosynthesis relies on the oxidation of inorganic compounds, such as hydrogen sulfide, methane, or ammonia, to generate energy.

"There were dense beds of #clams, each up to 9 inches long, and snow-like #MicrobialMats creating an ethereal undersea dusting, dozens of feet wide. This is the first time #chemosynthesis-based communities directly observed at extreme depths... Long-standing theories suggest that chemosynthesis-based communities are widespread in hadal trenches, but few have been discovered"

Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard

Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.

Deep-sea #hydrothermal vents are hot springs on the #ocean floor.

Around these vents, far from any sunlight, vibrant biological communities are found.

Here, #microbes play the role of primary producers through #chemosynthesis—similar to the role that plants play on land through photosynthesis.

Now, a newly discovered bacterial species from a hydrothermal vent throws light on microbial #evolution.

A new bacterial species from a hydrothermal vent throws light on microbial evolution

Deep-sea hydrothermal vents are hot springs on the ocean floor. Sea water penetrates into the ocean crust, becomes heated, and rises to the seafloor surface carrying dissolved nutrients. Around these vents, far from any sunlight, vibrant biological communities are found. Here, microbes play the role of primary producers through chemosynthesis—similar to the role that plants play on land through photosynthesis.

"Eight distantly related groups, or phyla, of #bacteria made the #enzymes to use #hydrogen and #CarbonMonoxide. Clearly #chemosynthesis is a far more widespread strategy in the oceans than previously thought!"

Bacteria use life's original energy source to thrive in the ocean's lightless depths

In the deep, dark ocean, sunlight-deprived bacteria turn to different sources of energy: dissolved hydrogen and carbon monoxide.
