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.^{[clarification needed]} 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]

T. kivui has been shown (with a technical readiness level of 4), to produce acetate with an input of H₂ and CO₂. This process could be used as the initial stage in an alternative food source production system.^[5]
