Abstract

AIMS

The cyanobacterial genus, Limnospira (anc. Arthrospira Stizenberger ex Gomont 1892), commonly called "Spirulina", is widely used for commercial purposes because of its high protein content and beneficial probiotic metabolites. Thus, the taxonomy of this genus is important because of its consequences for food applications.

METHODS AND RESULTS

We constructed a database with formation on all Limnospira strains plus new ones from 72 new French isolates. We used a polyphasic approach (phylogenetic, phylogenomic, presence or absence of coding DNA sequences, morphological, and ultrastructure analyses) to confirm that the species A. platensis belonged to the genus Limnospira (L. platensis Gomont comb. nov. Basionym. Arthrospira platensis Gomont 1892) and that the genus Limnospira was monospecific, only represented by L. platensis.

CONCLUSIONS

This study highlighted the large intra-specific diversity of L. platensis, independent of the affiliations of the phylogenetic clades or geographical location of the habitats and the subsequent physiological and metabolic plasticity.

摘要

目的

蓝细菌属 Limnospira（旧称 Arthrospira Stizenberger ex Gomont 1892），通常被称为“螺旋藻”，因其高蛋白含量和有益的益生菌代谢物而被广泛用于商业用途。因此，该属的分类学很重要，因为它对食品应用有影响。

方法和结果

我们构建了一个数据库，其中包含所有 Limnospira 菌株的信息，加上来自 72 个法国新分离株的新菌株。我们使用多相方法（系统发育、系统基因组学、编码 DNA 序列的存在或不存在、形态学和超微结构分析）来确认物种 A. platensis 属于 Limnospira 属（L. platensis Gomont comb. nov. 原名 Arthrospira platensis Gomont 1892），并且 Limnospira 属是单种属，仅由 L. platensis 代表。
