Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain Z29T belongs to the genus Chitinophaga in the family Chitinophagaceae . Levels of 16S rRNA gene sequence similarity between strain Z29T and the type strains of recognized species of the genus Chitinophaga ranged from 92.7 to 98.2 %. The main fatty acids of strain Z29T were iso-C15 : 0, C16 : 1ω5c and iso-C17 : 0 3-OH. It also contained menaquinone 7 (MK-7) as the respiratory quinone and homospermidine as the main polyamine. The polar lipid profile contained phosphatidylethanolamine, unknown aminolipids, unknown phospholipids and unknown lipids. The total DNA G+C content of strain Z29T was 51.3 mol%. Phenotypic properties and chemotaxonomic data supported the affiliation of strain Z29T with the genus Chitinophaga . The low level of DNA–DNA relatedness (ranging from 14.6 to 29.8 %) to the type strains of other species of the genus Chitinophaga and differential phenotypic properties demonstrated that strain Z29T represents a novel species of the genus Chitinophaga , for which the name Chitinophaga longshanensis sp. nov. is proposed. The type strain is Z29T ( = CCTCC AB 2014066T = LMG 28237T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.067249-0
