| Psychrophilic bacteria: an organism which grows optimally at or below 15oC, which has an upper limit for growth at ca. 20oC, and which has a lower limit of growth of 0oC or lower. |
| Kinetics of psychrophilic anaerobic sequencing batch reactor treating flushed dairy manure. |
| This wide range of conditions contributes to the diversity of halophile barophilic, alkaliphilic, and psychrophilic characteristics in addition to their obligate halophilicity. |
| Psychrophilic enzymes are present in psychrophiles, organisms that have adapted to very cold climates, such as those microorganisms living in the Artic and Antarctic regions. |
| Meanwhile, Earth-dwelling extremophile microorganisms, both thermophilic and psychrophilic, are variously adapted to temperatures that would fry us or freeze us. |
| The majority of psychrophilic bacteria are in the gram-negative genera Pseudomonas, Flavobacterium, Achromobacter, and Alcaligenes. |
