Strain HY9T is aerobic, heterotrophic and rose-pigmented. The cells are non-motile and curved, i.e. ring-like or horseshoe-shaped. The 16S rRNA gene sequence of strain HY9T was determined and blast searches revealed that it possessed significant sequence similarities with respect to Cyclobacterium species (92.8–93.6 %). Phylogenetic analysis confirmed that strain HY9T was tightly clustered with members of the genus Cyclobacterium. The cellular morphology and chemotaxonomic and phenotypic properties of strain HY9T showed that it should be classified as a member of the genus Cyclobacterium. Significant evolutionary distances and a range of phenotypic features distinguished strain HY9T from previously described Cyclobacterium species. Hence, strain HY9T represents a novel species in the genus Cyclobacterium, for which the name Cyclobacterium lianum sp. nov. is proposed. The type strain is HY9T (=CGMCC 1.6102T=JCM 14011T). On the basis of this study and previously described properties of Cyclobacterium species, an emended description of the genus Cyclobacterium is proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64510-0
