An orange-colored bacterial strain, ICM 1-15(T), was isolated from greenhouse soil. The 16S rRNA gene sequence of this strain showed the highest sequence similarity with Niabella ginsengisoli GR10-1(T) (95.2%) and Niabella yanshanensis CCBAU 05354(T) (95.0%) among the type strains. The strain ICM 1-15(T) was a strictly aerobic, Gram-negative, non-spore-forming, non-motile, flexirubin pigment-producing, short rod-shaped bacterium. The strain grew at 15-35°C (optimum, 25°C), at a pH of 5.0-8.5 (optimum, pH 6.5), and in the presence of 0-3% NaCl (optimum, 1%). The DNA G+C content of strain ICM 1-15(T) was 43.6 mol%. It contained MK-7 as the major isoprenoid quinone and iso-C15:0 (38.9%), iso-C15:1 G (20.3%), and iso-C17:0 3-OH (12.9%) as the major fatty acids. On the basis of evidence from our polyphasic taxonomic study, we concluded that strain ICM 1-15(T) should be classified within a novel species of the genus Niabella, for which the name Niabella terrae sp. nov. is proposed. The type strain is ICM 1-15(T) (=KACC 17443(T) =JCM 19502(T)).
一株橙色的细菌菌株，ICM 1-15(T)，从温室土壤中分离得到。该菌株的 16S rRNA 基因序列与模式菌株 Niabella ginsengisoli GR10-1(T)（95.2%）和 Niabella yanshanensis CCBAU 05354(T)（95.0%）具有最高的序列相似性。菌株 ICM 1-15(T)是一种严格需氧、革兰氏阴性、非孢子形成、非运动、产生 flexirubin 色素、短杆状细菌。该菌株在 15-35°C（最佳温度 25°C）、pH 值为 5.0-8.5（最佳 pH 值 6.5）和 0-3%NaCl（最佳浓度 1%）的条件下生长。菌株 ICM 1-15(T)的 DNA G+C 含量为 43.6mol%。它含有 MK-7 作为主要的异戊二烯醌和 iso-C15:0（38.9%）、iso-C15:1 G（20.3%）和 iso-C17:0 3-OH（12.9%）作为主要脂肪酸。基于多相分类学研究的证据，我们得出结论，菌株 ICM 1-15(T)应属于 Niabella 属的一个新种，因此提议将其命名为 Niabella terrae sp. nov.。模式菌株为 ICM 1-15(T)=KACC 17443(T)=JCM 19502(T)。
