A Gram-negative, aerobic, moderately halophilic bacterium, designated strain Z35T, was isolated from a Chinese traditional cured meat produced in Wuhan. The isolate grew with 1-20% NaCl (optimum 10%), at 4-42 degrees C (optimum 37 degrees C) and at pH 4.5-8.5 (optimum pH 7.0). Cells of strain Z35T were not motile and were rod or oval shaped. The genomic DNA G+C content was 59.1 mol%. The isoprenoid quinones were Q-9 (88.96%), Q-8 (9.46%) and Q-10 (1.58%). The major fatty acids were C19:0 cyclo omega8c, C16:0 and C17:0 cyclo. Phylogenetic analysis based on 16S rRNA gene sequence analysis indicated that strain Z35T was closely related to the type strains of Kushneria species with 93.7-95.3% sequence similarities. Phylogenetic analysis based on 23S rRNA gene sequence similarity values also confirmed the phylogenetic position of the isolate. Therefore, based on the phenotypic, chemotaxonomic and phylogenetic evidence, strain Z35T is affiliated to Kushneria, but is clearly differentiated from other species of this genus and represents a new member, for which the name Kushneria sinocarnis sp. nov. is proposed. The type strain is Z35T (=CCTCC AB 209027T =NRRL B-59197T =DSM 23229T).
一株革兰氏阴性、需氧、中度嗜盐的细菌,被命名为 Z35T 菌株,从武汉生产的一种中国传统腌制肉中分离得到。该分离物在 1-20%NaCl(最佳 10%)、4-42°C(最佳 37°C)和 pH4.5-8.5(最佳 pH7.0)的条件下生长。Z35T 菌株的细胞没有运动性,呈杆状或椭圆形。基因组 DNA G+C 含量为 59.1mol%。类异戊二烯醌为 Q-9(88.96%)、Q-8(9.46%)和 Q-10(1.58%)。主要脂肪酸为 C19:0 环 ω8c、C16:0 和 C17:0 环。基于 16S rRNA 基因序列分析的系统发育分析表明,Z35T 菌株与 Kushneria 属的模式菌株密切相关,序列相似度为 93.7-95.3%。基于 23S rRNA 基因序列相似性值的系统发育分析也证实了该分离株的系统发育地位。因此,基于表型、化学分类学和系统发育证据,Z35T 菌株属于 Kushneria,但与该属的其他种明显不同,代表一个新的成员,建议将其命名为 Kushneria sinocarnis sp. nov.。模式菌株为 Z35T(=CCTCC AB 209027T=NRRL B-59197T=DSM 23229T)。
