Niabella ginsengisoli sp. nov., isolated from soil cultivated with Korean ginseng.
The taxonomic status of a yellow- to light orange-coloured strain isolated from soil of a Korean ginseng field was established based on a polyphasic investigation. The novel isolate, strain GR10-1(T), was an obligately aerobic, Gram-staining-negative, non-motile, flexirubin-pigment-producing, short rod-shaped bacterium. The strain grew optimally at 28-30 degrees C, at pH 7.0 and in the presence of 0-1 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences demonstrated that the new isolate showed the highest sequence similarities with Niabella aurantiaca R2A15-11(T) (95.1 %) and Niabella soli JS13-8(T) (94.6 %). The DNA G+C content of strain GR10-1(T) was 43 mol%. It contained iso-C(15 : 1) G (36.4 %) and iso-C(15 : 0) (32.8 %) as the major fatty acids (>10 %) and MK-7 as the major isoprenoid quinone. On the basis of evidence from our polyphasic taxonomic study, it was concluded that strain GR10-1(T) should be classified within a novel species of the genus Niabella, for which the name Niabella ginsengisoli sp. nov. is proposed. The type strain is GR10-1(T) (=KACC 13021(T) =JCM 15444(T)).
