Diversity of magnetotactic bacteria of the Moskva River

Аннотация

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.
