Summary
Two strains of Pelodictyon clathratiforme have been successfully maintained in culture in a partly purified state. Their maintenance under laboratory conditions requires low light intensity and low sulfide concentrations.
The formation of the characteristic three-dimensional nets appears to be the consequence of occasional branching at the contiguous poles of two cells in a chain, to form a ring which expands by subsequent normal cell growth and division. Both strains contain the chlorobium vesicles typical of other green bacteria, and their absorption spectra indicate the presence of the chlorophyllous pigments characteristic of this group. Unlike other green bacteria so far studied, P. clathratiforme produces gas vacuoles, homologous in structure to those of blue-green algae.
