Magnetospirillum kuznetsovii sp. nov., a novel magnetotactic bacterium isolated from a lake in the Moscow region

Abstract

Strain LBB-42^T was isolated from sediment sampled at Lake Beloe Bordukovskoe, located in the Moscow region (Russia). Phylogenetic analyses based on 16S rRNA gene sequencing results assigned the strain to the genus Magnetospirillum. Major fatty acids were C16 : 1ω7c, C16 : 0 and C18 : 1 ω9/C18 : 1 ω7. Genome sequencing revealed a genome size of 4.40 Mbp and a G+C content of 63.4 mol%. The average nucleotide identity and digital DNA-DNA hybridization values suggested that strain LBB-42^T represents a new species, for which we propose the name Magnetospirillum kuznetsovii sp. nov., with the type strain LBB-42^T (=VKM B-3270^T=KCTC 15749^T).
