Psychrophiles include bacteria, lichens, snow algae, phytoplankton, fungi, and insects. Among the bacteria that can tolerate extreme cold are Arthrobacter sp., Psychrobacter sp. and members of the genera Halomonas, Pseudomonas, Hyphomonas, and Sphingomonas. [13]

True psychrophiles: They are sensitive to temperatures over 20°C. Optimum growth occurs at 15°C or below. Found in very cold environments such as ocean depths, Arctic, and the Antarctic regions. They seldom cause disease or food spoilage.

2022年4月8日 · Some common examples of psychrophiles include Psychrobacter members of Halomonas species, psychrophilic species of Pseudomonas and Alteromonas sps, Hyphomonas spp, Sphingomonas spp, Chryseobacterium greenlandensis, Desulfotalea psychrophila, Psychrobacter arcticus, etc.

2021年2月27日 · Psychrophiles are those that prefer colder temperature for growth and activity. The differing temperature requirement for growth and survival is associated with the expression of genetic elements (allele s) resulting in a phenotype (enzyme) suited to …

Psychrophiles are extremophilic organisms that are capable of growth and reproduction in extreme low temperatures, ranging from −20 °C to +10 °C. They are found in places that are permanently cold, regions of poles and deep sea.

Psychrophiles are organisms that have successfully colonized the environments characterized by exceptionally low temperatures. Actually, cold areas represent the majority of the biosphere on Earth ( Margesin and Miteva, 2011 ).

2021年9月24日 · Psychrophiles are a subtype of the Extremophilic organisms characterized by withstanding low temperatures, usually between -20 ° C and 10 ° C, and by occupying permanently cold habitats.

2012年5月8日 · These kinds of microorganisms are called psychrophiles, meaning “cold-loving,” in contrast to mesophiles that prefer relatively balmy conditions, like humans do. Psychrophiles often grow at below-freezing temperatures and some can even carry out active metabolism when they should be frozen solid, at temperatures as cold as -27˚F (-33˚C).

On the other hand, examples of psychrotrophs, which are also known as psychrotolerants, include several bacterial genera such as Pseudomonas, Brochothrix, Buttiauxella, Carnobacterium, Halomonas, Leuconostoc, Acinetobacter, Exiguobacterium, Serratia, Rhodococcus, Rahnella, and Pantoea; genera of filamentous fungi such as Alternaria, Aspergillus,...

Psychrophiles or Cryophiles (adj. cryophilic) are extremophilic organisms that are capable of growth and reproduction in cold temperatures. They can be contrasted with thermophiles, which thrive at unusually hot temperatures.
