Green sulfur bacteria examples

WebGreen Sulfur Bacteria. It is a group of photoautotrophic bacteria that can perform anoxygenic photosynthesis. Most of them are nonmotile and obligate anaerobes. They have bacteriochlorophyll pigments c, d, a or e. Also, they use sulphide as their ultimate electron donor for photosynthesis. Thus, they can thrive well in sulfur-rich environments ... WebThe Chlorobi (green sulfur bacteria) are obligate anaerobes, use reduced sulfur compounds as electron sources and also contain chlorosomes. The Firmicutes (e.g. heliobacteria) are Gram-positive anaerobes that prefer high light environments, use light energy to fix nitrogen and grow on organic compounds. ... For example, H 2 production …
