Research Abstract

Magnetotactic bacteria possess nano-sized prokaryotic magnetic organelles, magnetosomes. We developed live cell imaging technique by using fluorescence proteins to analyze cellular dynamics of the magnetosomes. By fusions of fluorescence proteins with magnetosomal proteins, we labeled magnetosome membrane and magnetosomal cytoskeleton in Magnetospirillum magneticum AMB-1. We successfully observed segregation of the magnetosomes to daughter cells during cell division.
