Question
An Archaea bacteria is cultured from the Dead Sea and will grow only at 300g/L salt and will not grow below 110g/L. This organism would be classified asGroup of answer choicesobligate thermophilefacultative halophileobligate halophilemoderate halophilemesohalophile
Solution
This organism would be classified as an obligate halophile. Obligate halophiles require high salt concentrations for growth, typically a minimum of 2M NaCl. The Dead Sea, from where this bacteria is cultured, is one of the saltiest bodies of water in the world, making it a suitable environment for obligate halophiles.
