WebErythroxanthin sulfate, a dominant carotenoid species in the membranes (>70%), is found not to transfer the absorbed light energy to bacteriochlorophyll (Bchl), and its RR spectra are similar between the in vivo and in vitro states. These observations indicate that erythroxanthin sulfate does not interact with either Bchl or proteins in the ... WebAug 1, 2006 · Two pigments, erythroxanthin sulfate and bacteriorubixanthinal, are, to our knowledge, specific for Erb. genus (but also are found in the freshwater AAP Erm. ramosum). Between these two pigments, bacteriorubixanthinal appears to be a better tracer, since erythroxanthin sulfate is not functionally related to photosynthesis.
