Abstract

The taxonomic position of a novel halophilic endospore-forming bacterium previously isolated from a desert iguana was investigated by 16S rRNA gene sequencing. Comparative sequence analyses showed the unidentified bacterium to be phylogenetically loosely associated with some other spore-forming (Bacillus pantothenticus, Sporosarcina halophila) and non-spore-forming (Marinococcus albus) halotolerant bacteria. Based on the phenotypic and phylogenetic distinctiveness of the unidentified bacterium, it is proposed that it is classified in the genus Bacillus as a new species, Bacillus dipsosauri.

一种耐盐芽孢杆菌的系统发育特征:双索芽孢杆菌的描述。
利用16S rRNA基因测序技术研究了从沙漠鬣蜥中分离到的一种新的嗜盐内孢子形成细菌的分类位置。序列比较分析表明,该细菌在系统发育上与其他一些产生孢子的细菌(如泛孢芽孢杆菌、嗜盐芽孢杆菌)和不产生孢子的耐盐细菌(如Marinococcus albus)有较弱的亲缘关系。基于该未鉴定细菌的表型和系统发育特征,我们建议将其分类为芽孢杆菌属(Bacillus dipsosauri)新种。
