Strain CBS-1T was found to be non-sporulating, Gram-negative, with optimal growth at 75–80 °C. It grew on a wide range of carbon sources, including glucose, lactose, maltose, starch, sorbitol and pyruvate amongst others. The DNA G+C content of strain CBS-1T was 31.9 mol%. The 16S rRNA gene sequence analysis indicated that the strain was a member of the genus Fervidobacterium. The high concentration of C16 : 0 (52.2 %) in the fatty acid profile of the cell envelope supported its inclusion as a member of the genus Fervidobacterium. On the basis of the low values of DNA–DNA hybridization (25.8 and 20.5 %) and phenotypic features, strain CBS-1T represents a novel species of the genus Fervidobacterium, for which the name Fervidobacterium changbaicum sp. nov. is proposed. The type strain is CBS-1T (=DSM 17883T=JCM 13353T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64758-0
