To the Moon and Back: This could expand the realm of the habitable zone, the area in which life haalofiles exist, to colder Mars-like planets.
Halophiles are extremophiles that thrive in environments with very high concentrations of salt. In a two-year laboratory study, scientists subjected these organisms to increasingly lower temperatures to determine the coldest temperatures at which the microbes could survive and reproduce.
The halophiles and methanogens are part of a hardy group of microbes called extremophiles, which thrive in the harshest environments on Earth.
My Apollo 11 Adventure. The halophiles and methanogens used in the experiments are from Antarctic lakes.
High salinity represents an extreme environment that relatively few organisms have been able to adapt to and occupy. The most common compatible solutes are neutral or zwitterionic, and include amino acids, sugars, polyols, betaines and ectoines, as well as derivatives of some of these compounds. The red color of deep salterns is xom to the carotenoids organic pigment in these archaea. In the laboratory, the halophiles displayed significant growth to 30 degrees Fahrenheit minus 1 degree Celsius.
These close-up images, taken by an electron microscope, reveal hwlofiles one-cell organisms called halophiles and methanogens.

These compatible solutes can be accumulated from the environment or synthesized. The discovery of planets with huge temperature disparities has scientists wondering what environments could be hospitable to life.
Methanogens are capable of growth on simple compounds like hydrogen and carbon dioxide for energy and can turn their waste into methane.
We do not sell, rent or trade our email lists. The researchers next plan to map the complete genetic blueprint for each extremophile. Picture of the Day Image Galleries. By inventorying all of the genes, scientists will be able to determine the functions of each gene, such as pinpointing the genes that protect an organism from the cold. Any osmolyte that helps an organism to survive osmotic stress Halophiles are extremophiles that thrive in environments with very high concentrations of salt.
In archaea, this adaptation is restricted to the the extremely halophilic ualofiles Haloarchaea often halofilex as Halobacteriaceae. Halophiles are chemoheterotrophs, using light for energy and methane as a carbon source under aerobic or anaerobic conditions. A study of extreme microbes on Earth suggests life can develop mechanisms to withstand freezing temperatures like those on Mars.
Long regarded as essentially barren of life, recent investigations galofiles Antarctic environments have revealed considerable microbial activity.
Halophiles: Champions of Environmental Adaptations and Their Industrial Applications
In a two-year laboratory study, the researchers discovered that some cold-adapted microorganisms not only survived but halofiiles at 30 degrees Fahrenheit, just below the freezing point of water. The brine culture in which they grow in the laboratory can remain in liquid form to minus 18 degrees Fahrenheit minus 28 degrees Celsiusso the potential is there for significantly lower growth temperatures.

The researchers are members of a unique collaboration of astronomers from the Space Telescope Science Institute and microbiologists from the University of Maryland Biotechnology Institute’s Center of Marine Biotechnology in Baltimore, Md. To use this method, the entire intracellular machinery — including enzymes, structural proteins, and charged amino acids that allow the retention of water molecules on their surfaces — must be adapted to high salt levels.
