Photodynamics of the bacteriochlorophyll
-carotenoid system, 2: influence of central metal, solvent and P-carotene on photobleaching of bacteriochlorophyll
At a depth of about 120 meters, Crowe and his colleagues found that the most common microbes lacked chlorophyll a but contained bacteriochlorophyll
e, a light-harvesting pigment that absorbs infrared light and is present in photoferrotrophs adapted to low-light conditions.

55,56) These compounds are diagenetic derivatives of photosynthetic pigments, isorenieratene and bacteriochlorophylls
e, respectively, from obligately anaerobic green sulfur bacteria.
This hypothesis has been recently boosted by experimental results which reveal long-lived quantum coherent excitonic dynamics in the energy transfer among bacteriochlorophylls
in photosynthetic complexes (Engel et al.
