Abstract
- One motile strain designated, YIM DR1026<superscript>T</superscript> was isolated from the roots of Psammosilene tunicoides collected from Gejiu, Yunnan province, China. The cells of strain YIM DR1026<superscript>T</superscript> were Gram-negative and short-rod shaped. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YIM DR1026<superscript>T</superscript> was a member of the genus Aureimonas and closely related to Aureimonas rubiginis (96.7%). DNA–DNA relatedness values between strain YIM 1026<superscript>T</superscript> and Aureimonas rubiginis BCRC 80440<superscript>T</superscript> was 38.2 ± 1.5%. The ANI value between YIM DR1026<superscript>T</superscript> and other Aureimonas members were below the cut-off level (95–96%) recommended as the average nucleotide identity (ANI) criterion for interspecies identity. Strain YIM DR1026<superscript>T</superscript> grew at 4–30 °C (optimum 28 °C), pH 4.0–9.0 (optimum pH 6.0–7.0) and tolerated NaCl (w/v) up to 1% (optimum 0%). Q-10 was sole the respiratory ubiquinone present in YIM DR1026<superscript>T</superscript>. Polar lipids of strain YIM DR1026<superscript>T</superscript> were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, sulfoquinovosyldiacylglycerol, unidentified aminolipid and unidentified polar lipid. The genomic G + C content was 64.6 mol%. The major fatty acids were C<subscript>18:1</subscript>ω7c, C<subscript>16:0</subscript> and summed feature 3 (C<subscript>16:1ω</subscript>7c/C<subscript>16:1ω</subscript>6c). Based on phenotypic, phylogenetic, chemotaxonomic and genome comparison, strain YIM DR1026<superscript>T</superscript> represents a novel species of the genus Aureimonas, for which the name Aureimonas psammosilene sp. nov. is proposed. The type strain is YIM DR1026<superscript>T</superscript> (= KCTC 42691<superscript>T</superscript> = NBRC 112412<superscript>T</superscript>). [ABSTRACT FROM AUTHOR]
