摘要

用显微镜和系统发育分析方法研究了莫斯科河Strogino地区趋磁细菌的多样性。趋磁球菌为主要形态。16S rRNA基因序列的系统发育分析显示,该菌株在Alphaproteobacteria纲Magnetococcales和Rhodospirillales中有13个OTUs。相关序列的占比分别为90%和10%。从所研究的群落中分离出一株趋磁螺旋藻。根据16S rRNA基因测序结果,鉴定该分离物为磁螺旋藻新种。

Diversity of magnetotactic bacteria of the Moskva River.

Diversity of magnetotactic bacteria in the Moskva River at the Strogino area was studied using microscopy and phylogenetic analysis. Magnetotactic cocci were the predominant morphotype. Phylogenetic analysis of the 16S rRNA gene sequences revealed 13 OTUs of the orders Magnetococcales and Rhodospirillales, class Alphaproteobacteria. The shares of the relevant sequences were 90 and 10%, respectively. An axenic culture of magnetotactic spirilla was isolated from the studied community. According to the results of the 16S rRNA gene sequencing, the isolate was identified as a new Magnetospirillum species.
