An extremotroph (from Latin extremus meaning "extreme" and Greek troph (τροφ) meaning "food") is an organism that feeds on matter that is not typically considered to be food to most life on Earth. "These anthropocentric definitions that we make of extremophily and extremotrophy focus on a single environmental extreme but many extremophiles may fall into multiple categories, for example, organisms living inside hot rocks deep under the Earth's surface."[1]
Examples
edit- Pestalotiopsis microspora: plastic eater
- Halomonas titanicae: metal eater [2]
- Geotrichum candidum: compact disk eater [3]
- Aspergillus fumigatus: printed circuit board eater [4]
- Deinococcus radiodurans: radioactive waste eater
- Actinobacteria from arid and desert habitats [5]
- Cold-tolerant cyanobacteria found in polar ice shelves [6]
Industrial uses
editExtremotrophs are used as bioremediation and biodegradation agents.[citation needed]
