Colwellia Demingiae
''Colwellia demingiae'' is a psychrophilic Antarctic bacterial species with the ability to synthesize docosahexaenoic acid. It is nonpigmented, curved-rod-like in shape, exhibiting facultative anaerobic growth, and possessing an absolute requirement for sea water. Its type strain is ACAM 459T. This bacteria is named after Jody Deming Jody W. Deming (born July 2, 1952) is an American oceanographer. She is a professor of Oceanography and a marine microbiologist at the University of Washington (UW). Her research interests include studies of cold adapted microbes in their relat ..., a professor and researcher at University of Washington and her research mentor, Rita Colwell.

Psychrophilic
Psychrophiles or cryophiles (adj. ''psychrophilic'' or ''cryophilic'') are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from to . They have an optimal growth temperature at . They are found in places that are permanently cold, such as the polar regions and the deep sea. They can be contrasted with thermophiles, which are organisms that thrive at unusually high temperatures, and mesophiles at intermediate temperatures. Psychrophile is Greek for 'cold-loving', . Many such organisms are bacteria or archaea, but some eukaryotes such as lichens, snow algae, phytoplankton, fungi, and wingless midges, are also classified as psychrophiles. Biology Habitat The cold environments that psychrophiles inhabit are ubiquitous on Earth, as a large fraction of the planetary surface experiences temperatures lower than 10 °C. They are present in permafrost, polar ice, glaciers, snowfields and deep ocean waters. These organisms can also be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
