Druce, in Mai Po Nature Reserve, Hong Kong. Growth of strain XY-R6T was observed at pH 5.0–9.5 (optimum 6.5–8.0), between 8 and 42 °C (optimum 28–34 °C), and in the presence of 0–9.5 % (w/v) NaCl (optimum 1–4 %). The predominant isoprenoid quinone was ubiquinone-10. The major fatty acids were summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) (55.61 %), C19 : 0cycloω8c (21.59 %) and C16 : 0 (11.24 %). The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, aminolipid, phosphatidylcholine and diphosphatidylglycerol. The genomic DNA G+C content of strain XY-R6T was 69.3 mol%. Phylogenetic analyses, based on 16S rRNA gene sequences, revealed that strain XY-R6T belonged to the family Rhodobacteraceae of the class Alphaproteobacteria and formed a distinct lineage, showing the highest gene sequence similarities to the members of genus Wenxinia (94.5–94.3 %), followed by the genera Profundibacterium (94.3 %), Defluviimonas (93.8–92.5 %), Oceanicola (93.8 %) and Cereibacter (93.7 %). Similarities to other genera within the family Rhodobacteraceae were below 94.0 %. Based on comprehensive phenotypic, phylogenetic and chemotaxonomic characterization, it is indicated that strain XY-R6T represents a novel species of a new genus in the family Rhodobacteraceae , for which the name Kandeliimicrobium roseum gen. nov., sp. nov. is proposed, with XY-R6T (=MCCC 1K01498T=KCTC 52266T=DSM 104294T) as the type strain. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002773
