Abstract |
Strain DCT-19T, representing a Gram-stain-positive, rodshaped,
aerobic bacterium, was isolated from a native plant
belonging to the genus Campanula on Dokdo, the Republic of
Korea. Comparative analysis of the 16S rRNA gene sequence
showed that this strain was closely related to Paenibacillus
amylolyticus NRRL NRS-290T (98.6%, 16S rRNA gene sequence
similarity), Paenibacillus tundrae A10bT (98.1%), and
Paenibacillus xylanexedens NRRL B-51090T (97.6%). DNADNA
hybridization indicated that this strain had relatively
low levels of DNA-DNA relatedness with P. amylolyticus
NRRL NRS-290T (30.0%), P. xylanexedens NRRL B-51090T
(29.0%), and P. tundrae A10bT (24.5%). Additionally, the genomic
DNA G + C content of DCT-19T was 44.8%. The isolated
strain grew at pH 6.0–8.0 (optimum, pH 7.0), 0–4%
(w/v) NaCl (optimum, 0%), and a temperature of 15–45°C
(optimum 25–30°C). The sole respiratory quinone in the strain
was menaquinone-7, and the predominant fatty acids were
C15:0 anteiso, C16:0 iso, and C16:0. In addition, the major polar
lipids were diphosphatidylglycerol and phosphatidylethanolamine.
Based on its phenotypic properties, genotypic distinctiveness,
and chemotaxonomic features, strain DCT-19T
is proposed as a novel species in the genus Paenibacillus, for
which the name Paenibacillus seodonensis sp. nov. is proposed
(=KCTC 43009T =LMG 30888T). The type strain of
Paenibacillus seodonensis is DCT-19T. |
