Fig 2.

Effect of oxygen and temperature on magnetosome chain (MC), magnetite crystal size, and morphology. (I) TEM micrograph panel of M. gryphiswaldense WT cells and their corresponding MCs and details of crystals under ox (35°C), mic (30°C), and anox (20°C) conditions. (II to IV) Magnetite crystal diameters (gray bars) of ∼350 analyzed particles per condition. Increase in temperature results in higher frequencies of small magnetite crystals (dark gray, ox; light gray, mic; medium gray, anox). Aer, aerobic; Anaer, anaerobic.
