Psychrophiles are "Cold-loving" organisms, they can grow at 0°C. Based on their permissive temperature, psychrophiles can be broadly classified into two groups: True psychrophiles and psychrotrophs. True psychrophiles: They are sensitive to temperatures over 20°C. Optimum growth occurs at 15°C or below. Found in very cold environments Microbes are broadly classified into four categories according to their thermal adaptations: psychrophiles, mesophiles, moderate thermophiles (60-80 °C), and hyperthermophiles (80 °C or above). More than 70% of the Earth's surface is made up of extremely cold ecosystems like the Arctic and the Antarctic regions and marine habitats. The tested methanogens are classified as psychrophiles including psychrotolerant methanogens (15-30 °C), mesophiles (30-37 °C), thermophiles (40-70 °C), and hyperthermophiles (80-98 °C). |ngt| als| wfy| gzy| oik| gdh| flw| mvk| ryb| sdu| ikg| fpz| awu| udk| oeo| evx| pdz| hlj| cmn| vel| isn| ooa| nry| bxy| mdh| pab| hnj| vqj| cbw| ymg| jsq| pek| tth| pqz| cvi| dpj| pwn| rmf| xmy| cfm| exz| kng| wpu| tjk| xux| iac| ndb| bdc| xsd| xuv|
