A Gram-negative, motile, aerobic and coccoid rod-shaped bacterium, designated strain YIM132180
T
, was isolated from a
Lepraria
sp. lichen collected from Pu’er, Yunnan Province, China. The strain grew at 15–35 °C (optimum, 25–28 °C), at 0–2% (w/v) NaCl (optimum, 0–1%) and at pH 6.0–9.0 (optimum, pH 7.0). The 16S rRNA gene sequence showed that strain YIM132180
T
had highest similarity (96.4%) with
Aureimonas endophytica
2T4P-2-4
T
, followed by
Aureimonas ureilytica
NBRC 106430
T
(95.7%) and
Aureimonas rubiginis
CC-CFT034
T
(95.6%). Phylogenetic analysis showed that the strain grouped with species of the genus
Aureimonas
. The genomic sequence was 4,779,519 bp and contained 4584 coding sequences (CDSs), 54 RNA genes, 3 complete rRNA genes and 47 tRNA genes. The major fatty acids (>10%) of strain YIM132180
T
were C
18:1
ω
7c, C-
16:0
and C
19:0
cyclo
ω
8c. The predominant menaquinone was ubiquinone 10 (Q-10). The polar lipid profile comprised diphosphatidylglycerol, phosphatidylcholine, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, unidentified phospholipid, amino lipid, lipid and most importantly sulfoquinovosyldiacylglycerol (SQDG). Based on the draft genome sequence, the G +C content of strain YIM132180
T
was 68.4 mol%. The results of the polyphasic taxonomic study, including phenotypic, chemotaxonomic, and phylogenetic analyses, showed that strain YIM132180
T
represents a novel species of the genus
Aureimonas
, for which the name
Aureimonas leprariae
sp. nov. is proposed. The type strain is YIM 132180
T
(=KCTC 72462
T
= CGMCC 1.17389
T
).
