The Fine Structure of Diplococcus Pneumoniae
نویسندگان
چکیده
The fine structure of an unencapsulated strain of Diplococcus pneumoniae is described. A striking feature of these bacteria is an intracytoplasmic membrane system which appears to be an extension of septa of dividing bacteria. The possible function of these structures and their relationship to the plasma membrane and other types of intracytoplasmic membranes found in pneumococcus is discussed.

متن کاملDefined medium for growth of two transformable strains of Diplococcus pneumoniae.
The classic bacterial transformation system, and one of the two most thoroughly studied systems, is Diplococcus pneumoniae. Transformation systems seem to offer a unique opportunity to study, at the molecular level, the hereditary material, deoxyribonucleate, and the molecular units of the organism it determines. Unfortunately this study has been retarded by a lack of well defined biochemical m...
