Examining the chemistry and magnetism of magnetotactic bacterium Candidatus Magnetovibrio blakemorei strain MV-1 using scanning transmission X-ray microscopy

Scanning transmission X-ray microscopy (STXM) measurements at the CK, O K and Fe L3 edges were used to study the magnetotactic bacterium Candidatus Magnetovibrio blakemorei strain MV-1 on an individual cell basis. Improved data acquisition methodologies resulting in higher quality results are presented. Visualization of magnetosomes from their O K-edge signal is demonstrated. The Fe L3 X-ray magnetic circular dichroism (XMCD) signal was used to …
