| Video Discription | Did you know organisms can not only survive in extreme environments, but thrive! Low temperature or cold loving organisms are called psychrophiles; high temperature loving organisms are called thermophiles and those that love extremely high temperature are calle hyperthermophiles, we talk in the video about the temperature range for each of these groups of organisms. We also discuss the adaptations that thermophiles & psychrophiles employ to be able to survive and maintain their cell structure in such environments. But extremophiles are not limited to extreme temperatures, some extremophiles love acidic or basic environments called acidophiles and alkaliphiles. However, both acidophiles and alkaliphiles must maintain near neutral internal pH even though they can handle extremely low and high pH in their external environment. Many alkaliphiles are also halophiles, meaning they love salt. These salt loving organisms can live in hypersaline lakes, soda lakes, brine, and some even love suger too, called osmophiles and those that love dry environments are called xerophiles. The last category of extremophile involved oxygen concentrations. Some organisms live in environments with low oxygen concentrations, called microaerophiles, some live in environments with no oxygen, called anaerobes. Anaerobes that can tolerate some oxygen are aerotolerant, while anaerobes that cannot tolerate oxygen are obligate anaerobes. Facultative aerobes are organisms that can grow in either oxic or anoic environments.
