Phylo-geographic study on highly novel slow-growing microorganisms

一种生长缓慢的需氧细菌，命名为Shr3，是从突尼斯的一个干旱地区分离出来的，它与所有其他已知生物的16S rRNA基因序列只有82%的相似性。与其他遗传、生化和生理特性一起，Shr3被证明是一个高度新颖的新物种，代表了变形杆菌门中的一个新纲。这一分类建议已经接受了专家的审查。Shr3菌株的副本(传代)已保存在英国国家工业、食品和海洋细菌收藏馆(NCIMB)。除了Shr3，还有两个分离物也被鉴定为新的分类群，即种、属、科、目或更高的分类群。

A slow-growing aerobic bacterium, named Shr3, was isolated from an arid area in Tunisia, and was only distantly related to all other known organisms at <82% similarity of 16S rRNA gene sequences. Along with other genetic, biochemical and physiological properties, the isolate Shr3 was shown to be a highly novel new species, representing a new Class within the Phylum Proteobacteria. This taxonomic proposal has been subject to expert reviews.A copy (sub-culture) of the Shr3 strain has been deposited at National Collection of Industrial, Food and Marine Bacteria (NCIMB), UK. In addition to Shr3, two more isolates were also characterized to propose new taxa, i.e., species, genera, families, orders, or higher.
