Abstract |
A moderately halophilic and alkalitolerant bacterial strain
NKC1-1T was isolated from commercial kimchi in Korea.
Strain NKC1-1T was Gram-stain-positive, aerobic, rod-shaped,
non-motile, and contained diaminopimelic acid-type murein.
Cell growth was observed in a medium containing 0–25%
(w/v) NaCl (optimal at 10% [w/v]), at 20–40°C (optimal at
37°C) and pH 6.5–10.0 (optimal at pH 9.0). The major isoprenoid
quinone of the isolate was menaquinone-7, and the
major polar lipids were phosphatidylglycerol and unidentified
phospholipids. Cell membrane of the strain contained
iso-C17:0 and anteiso-C15:0 as the major fatty acids. Its DNA
G + C content was 45.2 mol%. Phylogenetic analysis indicated
the strain to be most closely related to Geomicrobium halophilum
with 92.7–92.9% 16S rRNA gene sequence similarity.
Based on polyphasic taxonomic evaluation with phenotypic,
phylogenetic, and chemotaxonomic analyses, the strain represents
a novel species in a new genus, for which the name
Salicibibacter kimchii gen. nov., sp. nov. is proposed (= CECT
9537T; KCCM 43276T). |
