Profile of Bob B. Buchanan.

چکیده
On a clear June day in 1975, Bob Buchanan and two Oslo colleagues pulled up water samples from a lake in Norway, examining the microorganisms growing at various depths. “When we got to 6 meters,” Buchanan recalls, “there was a band of Chlorobium growing,” referring to a genus of green bacteria (now called Chlorobaculum) that belongs to a unique class of organisms called photolithotrophs. These bacteria require sunlight for photosynthesis but obtain cellular reductants from sulfur compounds rather than water. The bacteria buck the traditional chemical pathways for energy production and carbon fixation and instead use pathways discovered by Buchanan, a member of the National Academy of Sciences and emeritus professor at the University of California, Berkeley.
