An endospore producing, strict aerobic, Gram-stain-positive, orange-colored colony forming bacterium designated as strain JC1013 T was isolated from an orange pond near a solar saltern of Tamil Nadu, India. Phylogenetic analysis of the 16S rRNA gene sequences indicated that strain was affiliated to the family Bacillaceae of the phylum Firmicutes . Strain showed highest 16S rRNA gene sequence identity of 98.7% with Mesobacillus selenatarsenatis SF-1 T and below 98.3% with other members of the genus Mesobacillus . Strain JC1013 T produced carotenoid pigments and indole compounds. Major cellular fatty acids of strain JC1013 T were iso-C 15:0, anteiso-C 15:0 , C 16:0 3-OH, iso-C 17:0 ω10c and summed feature 4 (iso-C 17:1 I/ anteisoB). Polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids and four unidentified phospholipids. Strain JC1013 T constituted m -diaminopimelic acid as diagnostic cell wall amino acids. MK-7 is the predominant menaquinone of strain JC1013 T . The genome size of strain JC1013 T was 4.6 Mbp and its G + C content was 42.7 mol%. For the affirmation of strain’s taxonomic status, a detailed phylogenomic study was done. Based on the phylogenetic analyses, low ANI (84.6%), AAI (88.5%) values, in-silico DDH (< 29%) value, morphological, physiological and chemo-taxonomical characteristics, strain JC1013 T was clearly distinguished from the nearest phylogenetic neighbor, Mesobacillus selenatarsenatis SF-1 T to conclude that it is a new species of the genus Mesobacillus . We propose the name as Mesobacillus aurantius with type strain JC1013 T (= NBRC 114146 T = KACC 21451 T ).

橙黄色中芽孢杆菌 11 月,从太阳能盐场附近的橙色池塘中分离出来

从印度泰米尔纳德邦日光浴场附近的橙色池塘中分离出一种产生内生孢子的严格需氧革兰氏染色阳性橙色菌落形成细菌,命名为 JC1013 T 菌株。16S rRNA基因序列的系统发育分析表明该菌株隶属于厚壁菌门的芽孢杆菌科。菌株与 Mesobacillus selenatarsenatis SF-1 T 的 16S rRNA 基因序列一致性最高,为 98.7%,与 Mesobacillus 属的其他成员低于 98.3%。菌株 JC1013 T 产生类胡萝卜素色素和吲哚化合物。菌株 JC1013 T 的主要细胞脂肪酸是 iso-C 15:0、antiiso-C 15:0、C 16:0 3-OH、iso-C 17:0 ω10c 和总特征 4(iso-C 17:1 I / 反异 B)。极性脂质是二磷脂酰甘油、磷脂酰乙醇胺、磷脂酰甘油、两种未鉴定的氨基脂和四种未鉴定的磷脂。菌株 JC1013 T 构成间-二氨基庚二酸作为诊断细胞壁氨基酸。MK-7 是菌株 JC1013 T 的主要甲基萘醌。JC1013 T菌株基因组大小为4.6 Mbp,G+C含量为42.7 mol%。为了确认菌株的分类地位,进行了详细的系统发育研究。基于系统发育分析,低 ANI (84.6%)、AAI (88.5%) 值、in-silico DDH (< 29%) 值、形态、生理和化学分类学特征,菌株 JC1013 T 与最近的系统发育有明显区别邻居,Mesobacillus selenatarsenatis SF-1 T 得出结论,它是 Mesobacillus 属的一个新物种。我们建议将该名称命名为 Mesobacillus aurantius,类型菌株 JC1013 T (= NBRC 114146 T = KACC 21451 T)。
