Psychrophiles are "Cold-loving" organisms, they can grow at 0C. In many parts of the U.S., wastewater is collected, treated and then reused. Because thermophile enzymes still work at high temperatures, they are an integral part of the process. Sometimes they are found in the intestinal tracts of ruminants. Many thermophiles are archaea, though they can be bacteria or fungi. Also, methane and other biogases are of special interest to be collected and used as fuel, so it represents an alternative to generate energy and eliminate its potential as a pollutant. Several groups of protists have variable modes of nutrition: Some species are photoautotrophs, whereas close relatives are heterotrophs. Thermophiles are a type of extremophile, or organism that loves extremes. These microorganisms are valuable model systems for molecular biology and biotechnology. Only a few microbial species can grow at [] Extremophiles are organisms that have evolved to survive in environments once thought to be entirely uninhabitable. Methanogens are found in a wide variety of anaerobic environments (with the absence of oxygen). Halophiles: The halophiles, named after the Greek word for "salt-adoring", are extremophiles that flourish in high salt fixations. It encompasses unicellular prokaryotic organisms without a differentiated nucleus, as well as bacteria. A prokaryote collected from a hot spring in Yellowstone National Park provided scientists with a key protein for the polymerase chain reaction (PCR). 15 How are Bacteria and Archaea classified? They are common in wetlands, where they are responsible for marsh gas, and in the guts of animals such as ruminants and humans, where they are responsible for the methane .
