四个嗜盐古细菌菌株YCN1T,YCN58T,LT38T,和LT62T从运城盐湖(山西,中国)和塔里木盆地(新疆,中国),分别。系统发育和系统基因组分析表明,这四个菌株与相关的Halobacterium物种紧密聚集,Natronomonas,Halorientalis,和Halobellus,分别。AAI,ANI,这四个菌株及其各自属的相关物种之间的dDDH值低于拟议的物种划分阈值。菌株YCN1T,YCN58T,LT38T,和LT62T可以从目前的盐杆菌中区分出来,Natronomonas,Halorientalis,和Halobellus,分别,基于不同表型特征的比较。这四个菌株的极性脂质谱与Halobacterium属中各自的亲属非常相似,Natronomonas,Halorientalis,和Halobellus,分别。表型,系统发育,基于基因组的分析表明,菌株YCN1T,YCN58T,LT38T,和LT62T代表盐杆菌属中各自的新物种,Natronomonas,Halorentalis,和Halobellus,为此命名为yunchengenseHalobacteriumsp。11月。,溶淀粉自然单胞菌sp.11月。,Halorientalishalophilasp.11月。,和盐半带菌。11月。被提议,分别。
Four halophilic archaeal strains YCN1T, YCN58T, LT38T, and LT62T were isolated from Yuncheng Salt Lake (Shanxi, China) and Tarim Basin (Xinjiang, China), respectively. Phylogenetic and phylogenomic analyses showed that these four strains tightly cluster with related species of Halobacterium, Natronomonas, Halorientalis, and Halobellus, respectively. The AAI, ANI, and dDDH values between these four strains and their related species of respective genera were lower than the proposed threshold values for species delineation. Strains YCN1T, YCN58T, LT38T, and LT62T could be differentiated from the current species of Halobacterium, Natronomonas, Halorientalis, and Halobellus, respectively, based on the comparison of diverse phenotypic characteristics. The polar lipid profiles of these four strains were closely similar to those of respective relatives within the genera Halobacterium, Natronomonas, Halorientalis, and Halobellus, respectively. The phenotypic, phylogenetic, and genome-based analyses indicated that strains YCN1T, YCN58T, LT38T, and LT62T represent respective novel species within the genera Halobacterium, Natronomonas, Halorentalis, and Halobellus, for which the names Halobacterium yunchengense sp. nov., Natronomonas amylolytica sp. nov., Halorientalis halophila sp. nov., and Halobellus salinisoli sp. nov. are proposed, respectively.
