This page provides all possible meanings and translations of the word halobacteria
halobacteria, halobacterium, halobacter(noun)
halophiles in saline environments such as the Dead Sea or salt flats
Plural form of halobacterium.
In taxonomy, the Halobacteria are a class of the Euryarchaeota, found in water saturated or nearly saturated with salt. They are also called halophiles, though this name is also used for other organisms which live in somewhat less concentrated salt water. They are common in most environments where large amounts of salt, moisture, and organic material are available. Halobacteria can grow aerobically or anaerobically. Parts of the membranes of halobacteria are purplish in color, and large blooms of Halobacteria appear reddish, from the pigment bacteriorhodopsin, related to the retinal pigment rhodopsin. Bacteriorhodopsin is used to absorb light, which provides energy to create ATP. Halobacteria also possess a second pigment, halorhodopsin, which pumps chloride ions in the cell in response to photons, creating a voltage gradient and assisting in the production of energy from light. The process is unrelated to other forms of photosynthesis involving electron transport however, and halobacteria are incapable of fixing carbon from carbon dioxide.
