As most microorganisms do not colonize excessive habitats, they continue to be a extremely specialised area of interest. Thermophiles and hyperthermophiles reside at high temperatures, reaching 130°C in hot springs and hydrothermal vents (Kashefi & Lovley, 2003 ). The best progress temperature in tradition (122°C) was recorded for the anaerobic methanogenic archaeon Methanopyrus kandleri isolated from a black smoker within the Gulf of California (Takai et al., 2008 ). Psychrophiles thrive in chilly environments, even entrapped inside ice and snow. They thrive in varied extreme habitats that had been previously considered unsuitable for all times.
