Appendages of Clostridium bifermentans Spores

Abstract
Four distinct spore appendage types were detected in an electron microscope survey of 12 strains of Clostridium bifermentans . A smooth tubular appendage and a feather-like appendage are described in detail. In addition, hirsute tubular appendages and small pin-like appendages are depicted. Spores of four strains apparently lack appendages.
