Abstract
A Gram-stain-negative, strictly aerobic bacterial strain, designated
strain S27T, was isolated from soil near an artificial
pond in South Korea. Cells were non-motile short rods showing
oxidase- and catalase-positive activities. Growth of strain
S27T was observed at 20–40°C (optimum, 30°C), pH 5.0–7.0
(optimum, pH 6.0), and 0–0.5% (w/v) NaCl (optimum, 0%).
Ubiquinone-8 was detected as the sole respiratory quinone
and the major fatty acids were C16:0, cyclo-C17:0, and cyclo-
C19:0 ω8c. The G + C content of the genomic DNA was 62.4
mol%. Phosphatidylglycerol, phosphatidylethanolamine, and
an unidentified aminophospholipid were detected as the major
polar lipids. Phylogenetic analysis based on 16S rRNA gene
sequences showed that strain S27T formed a clearly distinct
phyletic lineage from closely related Paraburkholderia species
within the genus Paraburkholderia. Strain S27T was most
closely related to Paraburkholderia rhynchosiae WSM3937T,
Paraburkholderia ginsengiterrae DCY85T, Paraburkholderia
fungorum NBRC 102489T, and Paraburkholderia graminis
C4D1MT with 98.8%, 98.4%, 98.4%, and 97.7% 16S rRNA
gene sequence similarities, respectively. The DNA-DNA relatedness
level between strain S27T and the type strain of P.
rhynchosiae was 36.8 ± 2.6%. On the basis of phenotypic, chemotaxonomic
and molecular properties, strain S27T represents
a novel species of the genus Paraburkholderia, for which
the name Paraburkholderia lacunae sp. nov. is proposed. The
type strain is S27T (KACC 19714 T = JCM 32721T).
