A dark-pink-coloured bacterial strain, B4Y-8T, was isolated from a soil cultivated with ginseng. The 16S rRNA gene sequence of this strain showed highest similarity with Mucilaginibacter litoreus BR-18T (96.8%), Mucilaginibacter lutimaris BR-3T (96.6%) and Mucilaginibacter defluvii A5T (96.2%) among the type strains of species of the genus Mucilaginibacter. Strain B4Y-8T was a strictly aerobic, Gram-stain-negative, non-motile, short-rod-shaped bacterium producing a large amount of extracellular polymeric substance. The strain grew at 10-35°C (optimum, 25 °C), at pH 3.0-11.0 (optimum, pH 7.0) and in the presence of 0-1% (w/v) NaCl (optimum, 0%). The DNA G+C content of strain B4Y-8T was 49.0 mol%. It contained menaquinone 7 (MK-7) as the major isoprenoid quinone, and summed feature 3 (C16:1ω6c and/or C16:1ω7c) and iso-C15:0 as the major fatty acids. On the basis of evidence from the present polyphasic taxonomic study, strain B4Y-8T should be classified as representing a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter ginsengisoli sp. nov. is proposed. The type strain is B4Y-8T (=KACC 18152T=JCM 30759T).
