Abstract

A Gram-stain-negative, aerobic, motile and rod-shaped bacterium, the color of the bacterial colony ranges from light yellow to yellow, designated YC-2023-2T, was isolated from sediment sample of Yuncheng salt lake. Growth occurred at 15–45℃ (optimum 37℃), pH 6.0-9.0 (optimum pH 7.0-8.0) and with 0–8.0% NaCl (w/v, optimum 2.0%). The phylogenetic analysis based on 16S rRNA gene sequences showed that strain YC-2023-2T belonged to the family Kordiimonadaceae. The closely related members were Gimibacter soli 6D33T (92.38%), Kordiimonas lipolytica M41T (91.88%), Eilatimonas milleporae DSM 25217T (91.88%) and Kordiimonas gwangyangensis JCM 12864T (91.84%). The genome of strain YC-2023-2T was 2957513 bp, and the genomic DNA G+C content was 63.91%. The main respiratory quinone was Q-10 and the major fatty acids (>10%) were iso-C15:0, C16:0, C19:0 cyclo ω8c, Summed Feature 8 (C18:1 ω6c or C18:1 ω7c) and Summed Feature 9 (iso-C17:1 ω9c or C16:0 10-methyl). The major polar lipids consisted of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, unidentified glycolipid, unidentified lipid, and two unidentified aminolipids. Based on the phylogenetic, phenotypic and chemotaxonomic characteristics, strain YC-2023-2T is proposed to represent a novel species of a novel genus named Yunchengibacter salinarum gen. nov., sp. nov., within the family Kordiimonadaceae. The type strain is YC-2023-2T (= GDMCC 1.4502T = KCTC 8546T).

从运城盐湖沉积物中分离出的一种新的科迪蒙那科细菌--运城盐湖细菌新属，新种

从运城盐湖的沉积物样品中分离到一种革兰氏染色阴性、需氧、运动、杆状的细菌，菌落颜色从浅黄色到黄色不等，菌名为 YC-2023-2T。生长条件为 15-45℃（最适 37℃）、pH 值 6.0-9.0（最适 pH 值 7.0-8.0）、0-8.0%NaCl（w/v，最适 2.0%）。基于 16S rRNA 基因序列的系统进化分析表明，菌株 YC-2023-2T 属于科迪蒙那达科。近缘成员为 Gimibacter soli 6D33T (92.38%)、Kordiimonas lipolytica M41T (91.88%)、Eilatimonas milleporae DSM 25217T (91.88%)和 Kordiimonas gwangyangensis JCM 12864T (91.84%)。菌株 YC-2023-2T 的基因组为 2957513 bp，基因组 DNA G+C 含量为 63.91%。主要呼吸醌为 Q-10，主要脂肪酸（>10%）为异-C15:0、C16:0、C19:0 环 ω8c、总特征 8（C18:1 ω6c或 C18:1 ω7c）和总特征 9（异-C17:1 ω9c或 C16:0 10-甲基）。主要极性脂质包括磷脂酰乙醇胺、二磷脂酰甘油、磷脂酰甘油、不明糖脂、不明脂质和两种不明氨基脂质。根据系统发生学、表型学和化学分类学特征，YC-2023-2T 株系被认为是新属的一个新种，该新属被命名为 Yunchengibacter salinarum gen.模式菌株为 YC-2023-2T (= GDMCC 1.4502T = KCTC 8546T)。
