title: Morphological modifications of cells of Clostridium pasteurianum caused by growth on sulfite.
abstract: The morphology of Clostridium pasteurianum cells grown on 10(-2) M SO32- showed significant alteration in cell shape and the absence of the electron translucent reserve polysaccharide (amylopectin) when compared to sulfate-grown cells. At the lower sulfite concentrations (10(-3) and 10(-4)M SO32-) the cells showed the cytoplasmic changes noted above but the cell shapes were not modified.
