Abstract |
A strictly aerobic, motile, endospore-forming, rod-shaped
bacterium, designated HS21T, was isolated from rhizospheric
soil of the Korean fir tree (Abies koreana) from Halla mountain
on Jeju island, Korea. Growth of strain HS21T was observed
at pH 6.0–8.0 (optimum: pH 7.0), 0–2% (w/v) NaCl
and 4–30°C (optimum: 25°C). A comparative analysis of 16S
rRNA gene sequences showed that strain HS21T was most
closely related to Cohnella luojiensis HY-22RT (97.6%), followed
by C. lupini RLAHU4BT (97.4%) and C. collisoli NKM-
5T (97.2%). The genome of strain HS21T comprised a circular
chromosome of 7,059,027 bp with 44.8% G + C content. The
DNA-DNA relatedness values between strain HS21T and C.
luojiensis HY-22RT and C. lupini RLAHU4BT were 18.1% and
13.8%, respectively. The major cellular fatty acids (> 5%) of
the isolate were anteiso-C15:0, iso-C16:0, C16:0, and iso-C15:0. The
polar lipids present were diphosphatidylglycerol, phosphatidylglycerol,
phosphatidylethanolamine, lysylphosphatidylglycerol,
and three unidentified aminophospholipids. Based
on its phenotypic, phylogenetic, genomic, and chemotaxonomic
properties, strain HS21T represents a novel species of
the genus Cohnella, for which the name Cohnella abietis sp.
nov. is proposed. The type strain is HS21T (= KCTC 43028T
= CCTCC AB 2019010T). |
