INTRODUCTION 



This book contains the papers presented at a small, invitational 

 Symposium on Bacterial Photosynthesis held in Yellow Springs, Ohio 

 on March 18-20, 1963. The Charles F. Kettering Research Laboratory 

 was very pleased to serve as host for this conference. Research 

 progress on bacterial systems is moving rapidly and a review of the 

 present state of knowledge seemed appropriate. The organizing com- 

 mittee therefore invited some fifty-five overseas and American in- 

 vestigators to meet and exchange information at a small, informal 

 meeting held under the Foundation's auspices. The staff of the Charles 

 F. Kettering Research Laooratory was stimulated immensely by the 

 conference; we hope these papers will serve as a point of departure 

 for additional photosynthetic investigations,
