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 …

WebJun 16, 2014 · Green sulfur bacteria inhabit the lowermost part of the chemocline in the stratified environment due to their sensitivity to oxygen, their high sulfide tolerance and their dependence in light. Green sulfur bacteria are important drivers of oxidation of reduced sulfur compounds in the stratified, sulfide-containing environment receiving low ... Websulfur bacterium, plural Sulfur Bacteria, any of a diverse group of microorganisms capable of metabolizing sulfur and its compounds and important in the sulfur cycle (q.v.) in nature. Some of the common sulfur substances that are used by these bacteria as an energy source are hydrogen sulfide (H2S), sulfur, and thiosulfate (S2O32-).
