Green sulfur bacteria
WebGreen sulfur bacteria contain chlorosomes, organelles that are so efficient at harvesting light that green sulfur bacteria can grow at much lower light intensities than other light … WebThe green sulfur bacteria utilize H 2 S as an electron donor, so they can tolerate this toxic molecule. Most of the species are photoheterotrophs so they can assimilate few organic compounds as carbon source. The autotrophic species of this phylum use the reverse citric cycle to fix CO 2. The green nonsulfur bacteria only tolerate low ...
