Thermoanaerobacter kivui (formerly Acetogenium kivui) is a thermophilic, anaerobic, nonspore-forming species of bacteria.John A. Leigh and Ralph S. Wolfe. Acetogenium kivui gen. nov., sp. nov., a Thermophilic Acetogenic Bacterium. International Journal of Systematic Bacteriology. October 1983 vol. 33 no. 4 886 doi: 10.1099/00207713-33-4-886.
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.J. A. Leigh, F. Mayer and R. S. Wolfe. Acetogenium kivui, a new thermophilic hydrogen-oxidizing acetogenic bacterium. Archives of Microbiology. Volume 129, Number 4 (1981), 275-280, DOI: 10.1007/BF00414697. 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.M.D. Collins, P.A. Lawson, A. Willems, J.J. Cordoba, J. Fernadez-Garayzabal, P. Garcia, J. Cai, H. Hippie, J.A.E. Farrow. The Phylogeny of the Genus Clostridium: Proposal of Five New Genera and Eleven New Species Combinations. International Journal of Systematic Bacteriology. October 1994 vol. 44 no. 4 812-826 doi: 10.1099/00207713-44-4-812.
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.Lisa Marie Schmitz, Nicolai Kreitli, Lisa Obermaier, Nadine Weber, Michael Rychlik, Largus T. Angenent.
