Abstract
-
A Gram-stain-positive, polar flagella-containing, rod-shaped,
obligate aerobic, endospore-forming bacterium, strain
TK1655T, was isolated from the traditional Korean food
gochujang. The 16S rRNA sequence of strain TK1655T was
a member of the genus Oceanobacillus similar to that of the
type strain of Oceanobacillus oncorhynchi subsp. incaldanensis
DSM 16557T (97.2%), O. oncorhynchi subsp. oncorhynchi JCM
12661T (97.1%), O. locisalsi KCTC 13253T (97.0%), and O.
sojae JCM 15792T (96.9%). Strain TK1655T was oxidase and
catalase positive. Colonies were circular, smooth, low convex,
cream in colour, and measured about 0.5–1.0 mm in diameter.
The range for growth was 20–40°C (optimal, 30°C), pH 6.0–
10.0 (optimal, 7.0), and 2–16% (w/v) NaCl (optimal, 2%).
Additionally, the cells contained meso-DAP, and the predominant
isoprenoid quinone was MK-7. The complex polar
lipids were consisted of diphosphatidylglycerol (DPG), phosphatidylglycerol
(PG), phosphatidylcholine (PC). The major
cellular fatty acid components were iso-C15:0, anteiso-C15:0,
iso-C16:0, and anteiso-C17:0, and the DNA G+C content was
40.5%. DNA-DNA relatedness of our novel strain and reference
strain O. locisalsi KCTC 13253T, O. oncorhynchi subsp.
incaldanensis DSM 16557T, O. oncorhynchi subsp. oncorhynchi
JCM 12661T was 45.7, 43.8, and 41.9%. From the
results
of phenotypic, chemotaxonomic, and phylogenetic analyses of strain TK1655T, we propose the novel species Oceanobacillus gochujangensis sp. nov. The type strain is TK1655T (=KCCM 101304T =KCTC 33014T =CIP 110582T =NBRC 109637T). -
