EPR Studies of Photosynthetic Reaction Center in Acaryochloris marina

摘要

Acaryochloris marina (A.marina) is a new type of cyanobacteria that contains chlorophyll (Chl) d, instead of Chl a, as the major photosynthetic pigment. The organism contains 95 percent Chl d and 5 percent Chl a and undergoes oxygen evolving photosynthesis with 710-740 nm light absorbed by red absorption peak of Chl d. Only A. marina is known to use Chl d among all the cyanobacteria and plants that perform the oxygenic photosynthesis.
