Abstract |
A Gram-positive, strictly aerobic, nonmotile, yellowish, coccus-
rod-shaped bacterium (designated Gsoil 653T) isolated
from ginseng cultivating soil was characterized using a polyphasic
approach to clarify its taxonomic position. The strain
Gsoil 653T exhibited optimal growth at pH 7.0 on R2A agar
medium at 30°C. Phylogenetic analysis based on 16S rRNA
gene sequence similarities, indicated that Gsoil 653T belongs
to the genus Terrabacter of the family Humibacillus, and was
closely related to Terrabacter tumescens DSM 20308T (98.9%),
Terrabacter carboxydivorans PY2T (98.9%), Terrabacter terrigena
ON10T (98.8%), Terrabacter terrae PPLBT (98.6%), and
Terrabacter lapilli LR-26T (98.6%). The DNA G + C content
was 70.5 mol%. The major quinone was MK-8(H4). The primary
polar lipids were phosphatidylglycerol, diphosphatidylglycerol,
phosphatidyl-ethanolamine. The predominant
fatty acids were iso-C15:0, iso-C16:0, iso-C14:0, and anteiso-C15:0,
as in the case of genus Terrabacter, thereby supporting the
categorization of strain Gsoil 653T. However, the DNA-DNA
relatedness between Gsoil 653T and closely related strains of
Terrabacter species was low at less than 31%. Moreover, strain
Gsoil 653T could be both genotypically and phenotypically distinguished
from the recognized species of the genus Terrabacter.
This isolate, therefore, represents a novel species, for
which the name Terrabacter ginsengisoli sp. nov. is proposed
with the type strain Gsoil 653T (= KACC 19444T = LMG
30325T). |
