Abstract
The genus Alicyclobacillus is a thermoacidophilic bacterial genus found in diverse environments. Here, we report the draft genome sequence of Alicyclobacillus sp. strains CIJ1 and CIJ2 isolated from the Chinoike-Jigoku hot spring in Oita, Japan. Phylogenomic analyses suggest that these strains represent a candidate novel species within the genus.
