| ultramicroscopic structure of intrasporangium calvum (actinomycetales). | the electron microscopic observation of vesicles formed by intrasporangium calvum revealed that they do not contain spores. it thus seems that these vesicles should not be called sporangia. isolation and study of three other strains of actinomycetes forming similar vesicles indicated that such structures can be formed by actinomycetes with very different properties. the taxonomic value of vesicle formation in actinomycetes is questioned. | 1969 | 5344111 |
