Thermoanaerobacter kivui (formerly Acetogenium kivui) is a thermophilic, anaerobic, nonspore-forming species of bacteria.[2]
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 this organism principally produces acetic acid from substrates.[3] T. kivui was originally named Acetogenium kivui, which was the only species within a new genus. However, further 16S ribosomal RNA studies put this bacterium into genus Thermoanaerobacter and the previous genus was no longer necessary.[4]
