Extreme thermophiles are organisms that grow optimally: At high temperatures near or at that of boiling water. At human body temperature. At refrigerator temperatures. Independently of temperature (temperature has no influence on growth). At high magnesium ion concentrations.

Grow around 40-75°C. Absolute dependence on O2 for cellular processes. Grow with and without O2. Switch between using O2 and fermentation. Lowest temperature that supports growth. Grow around 65-120°C. Maximum temperature. Minimum temperature. Optimal temperature. Psychrophiles. Psychrotrophs. Mesophiles. Thermophiles. Extreme thermophiles. Barophiles. Acidophiles. Neutrophiles. Alkaliphiles. Halophiles. Facultative halophiles. Obligate/strict aerobes. Microaerophiles. Facultative anaerobes. Anaerobes. Aerotolerant anaerobes. Obligate/strict anaerobes. Use only small amounts of O2 (5%). Grow at about 0-30°C associated with foodborne illness. Thrive in high-salt environments, tolerate up to 35%. Associated with Dead Sea and the Great Salt Lake of Utah environments. Thrive between 20°C and 100°C. Can withstand the high-pressure environment of the deep sea. Do not use O2 in their metabolic processes. Can eliminate ROS. Tend to die in aerobic environments. Tolerate higher salt but may not grow well, for example, Staphylococcus aureus. Grow at pH <5 to pH 5. Live in areas such as hot springs and volcanic vents. Grow best in pH range of 5-8. Make up the majority of microorganisms. Temperature where cellular growth is highest. Highest temperature that supports growth. Tolerate O2, but don't use it. Have ways to deactivate ROS. Grow best around 10-50°C associated with most pathogens. Grow in the basic pH range of 9-11.

Basic Environmental Classification of Microorganisms Environmental Parameter: Temperature Classification: Hyperthermophile (growth above 80°C [176°F]) Thermophile (growth between 50°C [122°F] and 80°C [176°F]) Mesophile (growth between 15°C [59°F] and 45°C [113°F]) Psychrophile (growth below 15°C [59°F]) Environmental Parameter: pH Classification: Alkaliphile (growth above pH 9) Neutralophile (growth between pH 5 and pH 8) Acidophile (growth below pH 3) Environmental Parameter: Osmolarity Classification: Halophile (growth in high salt, greater than 2 M NaCl) Environmental Parameter: Oxygen Classification: Strict aerobe (growth only in oxygen) Facultative microbe (growth with or without oxygen) Microaerophile (growth only in small amounts of oxygen) Strict anaerobe (growth only without oxygen) Environmental Parameter: Pressure Classification: Barophile (growth at high pressure, greater than 380 atm) Barotolerant (growth between 10 and 500 atm)
