Abstract |
A Gram-stain-positive, obligately anaerobic, non-motile, nonspore-
forming, and rod-shaped bacterial strain, designated
KGMB01110T, was isolated from a faecal sample of a healthy
male in South Korea. Phylogenetic analysis based on 16S rRNA
gene showed that strain KGMB01110T belonged to Clostridium
cluster XIVa and was most closely related to Mediterraneibacter
glycyrrhizinilyticus KCTC 5760T (95.9% 16S rRNA
gene sequence similarity). The DNA G + C content of strain
KGMB01110T based on its whole genome sequence was 44.1
mol%. The major cellular fatty acids (> 10%) of the isolate
were C14:0 and C16:0. The strain KGMB01110T was positive for
arginine dihydrolase, β-galactosidase-6-phosphatase, and
alkaline phosphatase. The strain KGMB01110T also produced
acid from D-glucose and D-rhamnose, and hydrolyzed gelatin
and aesculin. Furthermore, HPLC analysis and UV-tests
of culture supernatant revealed that the strain KGMB01110T
produced butyrate as the major end product of glucose fermentation.
Based on the phylogenetic and phenotypic characteristics,
strain KGMB01110T represent a novel species of
the genus Mediterraneibacter in the family Lachnospiraceae.
The type strain is KGMB01110T (= KCTC 15684T = CCUG
72830T). |
