''Thermoanaerobacter kivui'' (formerly ''Acetogenium kivui'') is a
thermophilic,
anaerobic, non
spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, f ...

''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
Acetic acid , systematically named ethanoic acid , is an acidic, colourless liquid and organic compound with the chemical formula (also written as , , or ). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component ...
from substrates. ''T. kivui'' was originally named ''Acetogenium kivui'', which was the only species within a new genus. However, further
16S ribosomal RNA
16 S ribosomal RNA (or 16 S rRNA) is the RNA component of the 30S subunit of a prokaryotic ribosome (SSU rRNA). It binds to the Shine-Dalgarno sequence and provides most of the SSU structure.
The genes coding for it are referred to as 16S rRNA ...
studies put this bacterium into genus ''
Thermoanaerobacter'' and the previous genus was no longer necessary.
