Psychrophilic Microbiomes

Microbes living in the lowest temperature ranges are called psychrophiles. As most of our universal is largely cold, this indicates that extremophiles are common within an extensive range of habitats. Application of particular primers for environmental samples analysis showed a great presence of these actinobacterial group and revealed that these sequences could be recognized to novel groups of actinobacteria. The chapter focuses on the function of enzymes obtained from psychrophiles which covered a dominant role in living organisms present in cold environment. Psychrophilic enzymes having crystal structures were of significance to examine the properties of cold-active catalysts. Researchers have focused on them due to the biotechnological and industrial significance of psychrophilic enzymes. In 1996, Aghajari et al. crystallized the psychrophilic enzyme and investigated it by x-ray diffraction methods. The chemical stability of membrane lipids of bacteria are different from archaea based on the archaetidic acid and phosphatidic acid in bacteria and eukaryotes.
