Archaea and bacteria are referred to as prokaryotic unicellular organisms. Initially, archaea were classified as bacteria, thereby receiving the name archaebacteria. Archaea possess diverse physiological characteristics. They can be aerobic, facultative anaerobic, or obligate anaerobic. Nutritionally, they vary from chemolithoautotrophs to organotrophs. They are able to grow above 100ºC hence, categorized as hyperthermophiles and also possess mesophilic and psychrophilic characteristics.
