THE BACTERIAL PHOTOCHEMICAL APPARATUS 



Fig. 3. The effect of serial transfer ot Chlorobium thiosidfatophilum 

 in the absence of inorganic phosphate in the growth medium, on the 



content of polyphosphate in the cells. (Tq T4 = 4 transfers). 



Growth was relatively unaffected through three such transfers (To) 

 but polyphosphate was essentially depleted.
