Fig. 1From: Set-up of a pharmaceutical cell bank of Magnetospirillum gryphiswaldense MSR1 magnetotactic bacteria producing highly pure magnetosomesTransmission electron micrographs of a single magnetotactic bacterium originating from the CCB (a), or PCB (b). Both bacteria display a similar spirilla shape, a similar length of 1.2 µm and the presence of a chain of magnetosomes inside their organismBack to article page
