Structural Changes Associated with Extraction of Group E Spore Antigen of Clostridium botulinum

AUTOR(ES)
RESUMO

Spores of type E Beluga strain of Clostridium botulinum, which were hydrolyzed with HCl to remove the spore-specific antigen, showed a spore coat which was thinner and projected into the exosporium with multiple protuberances. The changes observed suggest that the antigen is a component of the spore coat connected with the maintenance of rigidity.
