Genomic analysis of a pure culture of magnetotactic bacterium Terasakiella sp. SH-1

Magnetotactic bacteria(MTB) display magnetotaxis ability because of biomineralization intracellular nanometer-sized, membrane-bound organelles termed magnetosomes. Despite having been discovered more than half a century, only few representatives MTB have isolated and cultured in the laboratory. In this study, we report genomic characterization novel marine magnetotactic spirillum strain SH-1 belonging to genus Terasakiella that was recently isolated. A gene encoding haloalkane dehalogenase, which is involved degradation chlorocyclohexane, chlorobenzene, chloroalkane, chloroalkene, identified. genome contained cysCHI soxBAZYX genes, thus potentially capable assimilatory sulfate reduction H 2 S using thiosulfate as electron donors oxidizing it sulfate. Genome also genes periplasmic dissimilatory nitrate reductases(napAB), reductase(nasA) nitrite reductases(nasB), suggesting gaining energy by converting ammonia. The pure culture sp. together with its results offers new opportunities examine biology, physiology, mechanisms MTB.
