Sulfur bacteria photosynthesis
Web3 Nov 2024 · Photosynthesis is the process used by plants, algae and some bacteria to turn sunlight into energy. The process chemically converts carbon dioxide (CO2) and water into food (sugars) and oxygen . WebMolecular mechanisms of photosynthesis in the phototrophic microorganisms can differ and depend on their location and pigments in the cells. This paper describes bacteria capable of molecular oxidizing hydrogen sulfide, specifically the families Chromatiaceae and Chlorobiaceae, also known as purple and green sulfur bacteria in the process of …

WebGreen sulfur bacteria perform a highly efficient photosynthesis due to the presence of light harvesting organelles, the chlorosomes, which are filled with special bacteriochlorophyll molecules. Green sulfur bacteria inhabit the lowermost part of the photic environments due to their efficient light capture. 13. 13 Green sulfur bacteria and ... WebThe purple sulfur bacteria (PSB) are part of a group of Pseudomonadota capable of photosynthesis, collectively referred to as purple bacteria. They are anaerobic or …
WebAll photosynthetic organisms locate their photosynthetic reaction centers within a membrane, which may be invaginations of the cytoplasmic membrane (Pseudomonadota), thylakoid membranes ("Cyanobacteria"), specialized antenna structures called chlorosomes (Green sulfur and non-sulfur bacteria), or the cytoplasmic membrane itself (heliobacteria).
