Abstract

Sphaerotilus natans is a filamentous sheath-forming bacterium. A method of selective fluorescent-labeling of its sheath using conventional reagents was developed. Terminal expansion of the sheath was confirmed by this method. In addition, ubiquitous cell growth was revealed by sequential phase-contrast microscopy of a filament. Based on this and earlier reports, a model of the sheath formation is proposed.
