ments in purple bacteria, has been shown by Fischer and Hasenkamp 387 

 to be closely related to chlorophyll-a. It is presumably the photosynthetic 

 principle in these bacteria. As far as can be judged, the green pigment is 

 identical in Rhodobacillus palustris (purple bacillus found in swamps), 

 Rhodovibrio ("purple" bacteria), and Thiocystis violacea (violet-colored 

 sulfur bacterium). 387
