Abstract

The localization of dipicolinic acid in dormant spores of Bacillus subtilis was examined by an immunoelectron microscopy method with colloidal gold-immunoglobulin G complex. The colloidal gold particles were distributed mainly in the core regions of dormant spores and were not observed in those of germinated or autoclaved spores. This result clearly demonstrates that dipicolinic acid is localized in the cores of dormant spores.
