How Photosynthetic Bacteria Harvest Solar Energy

The past several years have seen dramatic progress in our understanding of the reactions taking place in the early events of photosynthesis. This has been in large part due to research involving purple photosynthetic bacteria ([16][1], [28][2], [34][3], [35][4],[46][5], [56][6]). These anaerobic
