Abstract
A Gram-stain-negative, non-spore-forming, strictly aerobic, non-flagellated, non-gliding, rod-shaped bacterial strain, designated SMS-12T, was isolated from marine sand in a firth on the western coast of South Korea. Strain SMS-12T grew optimally at 25 °C, at pH 7.0–7.5 and in the absence of NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain SMS-12T fell within the clade comprising species of the genus
Mucilaginibacter
, forming a coherent cluster with the type strain of
Mucilaginibacter lappiensis
, with which it exhibited the highest 16S rRNA gene sequence similarity value of 97.5 %. Levels of sequence similarity to the type strains of the other species of the genus
Mucilaginibacter
and the other species used in the phylogenetic analysis were 93.3–96.4 % and <91.5 %, respectively. Strain SMS-12T contained MK-7 as the predominant menaquinone, and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine and one unidentified aminophospholipid; sphingolipids were present. The DNA G+C content was 41.8 mol% and the mean DNA–DNA relatedness with
M. lappiensis
KACC 14978T was 13 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain SMS-12T is separate from other species of the genus
Mucilaginibacter
. On the basis of the data presented, strain SMS-12T is considered to represent a novel species of the genus
Mucilaginibacter
, for which the name
Mucilaginibacter
sabulilitoris sp. nov. is proposed. The type strain is SMS-12T ( = KCTC 32111T = CCUG 62214T).
