Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Mar 15 2024American Chemical Society In ACS' Journal of Proteome Research, researchers detail a method for more accurate extremophile identification based on protein fragments instead of genetic material. The study identified two new hardy bacteria from high-altitude lakes in Chile -; an environment like early Mars.
Even though humans tend to avoid settling in extremely hot, cold or high-altitude areas, some microorganisms have adapted to live in such harsh locations. These extremophile microbes are of interest to astrobiologists who are searching for life on other planets. Researchers currently use individual gene sequencing to identify Earth-bound microbes, based on their DNA. However, current methods can't distinguish closely related species of extremophiles.
The researchers started their demonstration with water samples from five high-altitude Andean lakes more than 2.3 miles above sea level in the Chilean Altiplano. From the samples, the researchers cultivated 66 microbes and then determined which of two methods better identified the microorganisms: Related Stories With these methods, the researchers identified 63 of the 66 microorganisms that were cultivated from the high-altitude lake samples. For the three microorganisms that gene sequencing failed to identify because their genetic information wasn't in the available database, proteotyping identified two potentially new types of extremophile bacteria.
