A bacterial strain HLK1T was isolated from the human erythroleukemia cell line K562. This bacterium is a Gram-negative rod, motile with a polar flagellum. It is strictly aerobic, nonfermentative, and oxidase and catalase positive. Its optimal growth occurs at 37 °C at pH between 6.5 and 7.5. Phylogenetically, although it shares 98% similarity with the 16S rRNA of Phenylobacterium lituiforme, the DNA–DNA hybridization value between the two species is only 43%. HLK1T has a DNA G+C content of 71.2±0.2 mol%. It is a facultative intracellular organism and may have pathogenic relevance with humans and mammals. On the basis of the phylogenetic and phenotypic characterization, strain HLK1T is proposed to be classified in the genus Phenylobacterium, as P. zucineum sp. nov. The type strain is HLK1T (=CGMCC 1.3786T, DSM=18354).
