Abstract |
Gram-staining-negative, uniflagellated, rod-shaped, designated
as DCY110T, was isolated from sludge located in Gangwon
province, Republic of Korea. The phylogenetic tree of 16S
rRNA gene sequence showed that the strain DCY110T belonged
to the genus Rhodoferax with a close similarity to Rhodoferax
saidenbachensis DSM 22694T (97.7%), Rhodoferax
antarcticus DSM 24876T (97.5%), Rhodoferax ferrireducens
DSM 15236T (97.3%), and Rhodoferax fermentans JCM 7819T
(96.7%). The predominant isoprenoid quinine was ubiquinone
(Q-8). DNA G + C content was 62.8 mol%. The major
polar lipids were phosphatidylethanolamine and two unidentified
phospholipids. The major fatty acids (> 10%) were
C12:0, C16:0, summed feature 3 (which comprised C16:1 ω7c
and/or C16:1 ω6c). The DNA-DNA relatedness values between
the strain DCY110T and the closely related relatives used in
this study were lower than 70%. Based on the following polyphasic
analysis, the strain DCY110T is considered as a novel
species of the genus Rhodoferax, for which the name Rhodoferax
koreense sp. nov. is proposed. The type strain is DCY-
110T (= KCTC 52288T = JCM 31441T). |
