Abstract

Effects of an external electric field have been measured for Halobacterium salinarum loaded with fluorescent dye BCECF. Aggregates of the halobacteria are effectively formed by an electric field. The fluorescence lifetime of BCECF remains unchanged after the formation of the aggregates, suggesting that intracellular environments are not affected significantly by an external electric field in spite of the aggregate formation.
