Archaea vs. Eubacteria
The name halophile originates from the Greek languange, meaning salt-loving.
Halophiles live in bodies of water with a high salt concentration. They are usually found in water with a concentration of salt five times higher than that of an ocean. Some examples of where they live are Great Salt Lakes in Utah, Owens Lake in California, the Dead Sea, and in evaporation ponds. Very few organisms are able to surive in such high concentration, therefore it a very safe environment for the halophiles to live. Halophiles may also live in the gut of ruminants and humans.
Source of Energy
Halophiles use different sources of energy, some are aerobic and some are anaerobic; meaning that some need oxygen to grow (aerobic) but some do not require oxygen (anaerobic). Some examples of anaerobic halophiles are phototrophic, fermentative, sulfate-reducing, homoacetogenic and methanogenic species.
Archae reproduce asexually by the process of binary fission, budding and fragmentation.
Binary Fission [HD Animation]
In the video above, it shows the process of binary fission. Binary fission happens when a single cell (parent cell) divides to become two separate cells (daughter cells).
Halophiles produce sulfuric acid as a waste product.
The Archaea cell contains the plasma membrane, cytoplasm, cell wall, DNA, Flagella, Pili and the ribosomes.
The Eubacteria cell contains the plasma membrane, cytoplasm, cell wall, DNA, Flagella, Pili and the ribosomes.
Differences in Cell Structure
Both of the cells are very similar in structure, although archaea are different in the way that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
