Abstract
- A bacterial strain, designated S6 <superscript>T</superscript> , was isolated from the sandy soil on a rocky mountain in South China. Cells of S6 <superscript>T</superscript> were Gram-stain-negative, aerobic, non-spore-forming, non-motile and non-prosthecae-producing. 16S rRNA gene sequence analysis revealed the highest similarities to 12 uncultured bacteria, followed by Phenylobacterium sp. B6.10-61 (97.14 %). The closest related validly published strains are Caulobacter henricii ATCC 15253 <superscript>T</superscript> (96.15 %), Phenylobacterium conjunctum FWC 21 <superscript>T</superscript> (96.08 %) and Caulobacter mirabilis FWC 38 <superscript>T</superscript> (96.08 %). Phylogenetic analysis based on 16S rRNA gene, genome and proteome sequences demonstrated that S6 <superscript>T</superscript> formed a separated lineage in the genus Phenylobacterium . Strain S6 <superscript>T</superscript> contained Q-10 (97.5 %) as the major ubiquinone and C <subscript>18 : 1</subscript> ω7 c and C <subscript>16 : 0</subscript> as the major fatty acids. The polar lipid profile consisted of phosphatidylglycerol, an unknown phosphoglycolipid and three unknown glycolipids. The assembled genome comprises a chromosome with a length of 5.5 Mb and a plasmid of 96 014 bp. The G+C content was 67.6 mol%. The morphological, physiological, chemotaxonomic and phylogenetic analyses clearly distinguished this strain from its closest phylogenetic neighbours. Thus it is proposed that strain S6 <superscript>T</superscript> represents a novel species in the genus Phenylobacterium , for which the name Phenylobacterium montanum sp. nov. is proposed. The type strain is S6 <superscript>T</superscript> (=NBRC 115419 <superscript>T</superscript> =GCMCC 1.18594 <superscript>T</superscript> ).
