A Gram-stain-negative, strictly aerobic, motile, yellow, rod-shaped bacterium, designated ZDH117
, was isolated from soilsampled atthe Danxialandformin Guangdong Province, PR China. The 16S rRNA gene sequence of strain ZDH117
had highest similarityvalues to
DSM 7418
(97.5 %),
CP1D
(97.3 %) and
KACC 14949
(97.2 %). However, phylogenetic analyses based on 16S rRNA gene sequences demonstrated that strain ZDH117
clustered with
541
(96.17 %) and
DSM 19645
(95.95 %). The genomic average nucleotide identity values of ZDH117
with
DSM 7418
,
CP1D
and
KACC T
were 75.1, 75.2 and 75.0 %, respectively. The G+C content of the genomic DNA was 67.6 mol%. Strain ZDH117
was characterized to have ubiquinone-10 as the predominant respiratory quinone, sym-homospermidine as the major polyamine and summed feature 8 (C
ω6
and/or C
ω7
), C
-2OH, C
and summed feature 3 (C
ω6
and/or C
ω7
) as the major cellular fatty acids (>5 % of total). The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid, an unidentified phospholipid and three unidentified lipids. On the basis of its phenotypic, chemotaxonomic and phylogenetic characteristics, strain ZDH117
represents a novel species of the genus
, for which the name
sp. nov. is proposed. The type strain is ZDH117
(=KCTC 62894
=CCTCCAB 2018262
).
