Thermoanaerobacter kivui (formerly Acetogenium kivui) is an thermophilic anaerobic non-sporeforming species of bacteria.T. kivui was originally isolated from Lake Kivu in Africa. The growth range for the organism is 50 to 72°C at pH 5.3-7.3 with optimal growth conditions at 66°C and pH 6.4. Although the organism stains Gram-negative it shows a Gram-positive cell structure. The original genus Acetogenium was named because organism principally produces acetic acid from substrates. T.
