Abstract
A yellow-coloured bacterium, designated strain JGD-16T, was isolated from a tidal flat in Janggu-do, Garorim Bay, Taean-gun, Chungcheongbuk-do, Republic of Korea. Cells were Gram-stain-negative, aerobic, non-flagellated and short ovoid to coccoid-shaped. Growth was observed at 10–37 °C (optimum, 30 °C), pH 6.0–9.0 (pH 8.0) and with 1–5% (w/v) NaCl (2%). Results of 16S rRNA gene sequence analysis indicated that strain JGD-16T was closely related to
Altererythrobacter xiamenensis
LY02T (97.1 %),
Altererythrobacter aurantiacus
O30T (96.3 %),
Altererythrobacter ishigakiensis
JPCCMB0017T (95.8 %),
Altererythrobacter epoxidivorans
JCS350T (95.7 %) and
Altererythrobacter insulae
BPTF-M16T (95.3%). Phylogenomic analysis using the maximum-likelihood algorithm showed that strain JGD-16T formed a clade with the genus
Altererythrobacter
. The genomic DNA G+C content was 57.8 mol%. The predominant respiratory quinone was ubiquinone-10. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, a sphingoglycolipid, an unidentified glycolipid and an unidentified lipid. The major fatty acids were C18:1
ω7c (31.5 %) and C18:3
ω6c (19.6 %). On the basis of its phylogenomic, physiological and chemotaxonomical characteristics, strain JGD-16T represents a novel species within the genus
Altererythrobacter
, for which the name Altererythrobacter lutimaris JGD-16Tsp. nov. is proposed. The type strain is JGD-16T (=KCTC 72632T=KACC 21405T=JCM 33750T). We also propose the reclassification of
Altererythrobacter deserti
as Tsuneonella deserti comb. nov.,
Altererythrobacter estronivorus
as Croceicoccus estronivorus comb. nov. and
Altererythrobacter muriae
as Alteripontixanthobacter muriae comb. nov.
