摘要

Disclosed are a magnetospirillum magneticum, a preparation method therefor, and a use thereof. In the preset invention, a magnetospirillum magneticum Magnetospirillum sp. ME-1, CCTCC No: M2013260 which can produce superparamagnetic magnetosomes is separated fresh water. The strain is a magnetospirillum magneticum with a size of 2.62~4.83×0.44~0.62μm, and comprises a magnetosome chain consisting of 10 to 31 magnetosome particles. A component of each magnetosome is ferroferric oxide, is a cuboctahedron or an octahedron in shape, and has a size of 26±5nm which is in a superparamagnetic range. The magnetospirillum magneticum strain has a specific magnetosome gene island sequence and can produce magnetosomes with a yield of 177mg/L by directly using air fermental cultivation. The strain has excellent fermentability, and produces magnetosome particles which are superparamagnetic, and has a great industrialization popularization prospect.
