Strain TC-34T grew aerobically at 17–40 °C and pH 2.0–6.0, and optimally at 28 °C and pH 3.0. Analysis based on 16S rRNA gene sequences showed that strain TC-34T was phylogenetically related to members of the genus Alicyclobacillus, with the highest similarity (94.8 %) to Alicyclobacillus pomorum. Strain TC-34T showed a range of phenotypic characteristics that differentiated it from recognized Alicyclobacillus species, including growth temperature, assimilation of carbon sources and production of acids from a range of compounds. Strain TC-34T was able to oxidize ferrous iron and its growth was correlated with the oxidation of Fe2+ in culture medium. ω-Alicyclic fatty acids were not detected. On the basis of these results, it was concluded that strain TC-34T represents a novel species of the genus Alicyclobacillus, for which the name Alicyclobacillus ferrooxydans (type strain TC-34T=JCM 15090T=CGMCC 1.6357T) is proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.2008/000562-0
