What are phototrophic bacteria?
Phototrophic bacteria are also known as photosynthetic bacteria. Phototrophic bacteria consists of two groups, the purple and the green bacteria. Unlike the process of photosynthesis that is associated with blue-green algae and plants, phototrophic bacteria do not perform plant photosynthesis, do not contain chlorophyll-a, and do not produce oxygen. Their photosynthetic operation can instead produce hydrogen (depending on conditions) and carbon dioxide. Their growth also depends on sunlight. Several studies show phototrophic bacteria to be detoxifiers and/or consume waste matter. Phototrophic bacteria applications are being researched in various fields, including hydrogen-fuel production. The purple bacteria that’s also known as ‘purple sulfur bacteria’ is mostly known in the waste treatment industry. Although phototrophic bacteria may represent a small minority of all bacteria, they exist in virtually every environment on earth. The phototrophic bacteria in EM are the purple bacteria
