''Alicyclobacillus cycloheptanicus'' is a species of
Gram positive, strictly aerobic,
bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from soil. The species was originally classified as ''Bacillus cycloheptanicus'' in 1987, but further
16S rRNA 16S rRNA may refer to:
* 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.

studies found that the species belonged in the newly created genus ''Alicyclobacillus''. The species name refers ω-cycloheptane fatty acids in the cell membrane.
''A. cycloheptanicus'' was among the first three species reclassified from the genus ''
Bacillus'' to the newly created ''Alicyclobacillus'' in 1992, along with ''
A. acidocaldarius'' and ''
A. acidoterrestris''.
The optimum growth temperature for ''A. cycloheptanicus'' is 48 °C, and can grow in the 40-53 °C range. The optimum
pH is 3.5-4.5, and can grow in pH 3.0-5.5.
