Figure 5From: Large-scale production of magnetosomes by chemostat culture of Magnetospirillum gryphiswaldense at high cell densityElectron micrographs of cells in large scale culture at various phases, and purified magnetosomes. a, b, c, d,: 1-2 hr, 3-4 hr, 15-16 hr, and 24 hr, respectively, after DO became undetectable. e: purified magnetosomes. For each sample more than 20 micrographs were got and one representative image was selected.Back to article page
