Phototrophic bacterias also exist in composting chemicals. They are a type of bacteria that can derive their energy from light through a process known as photosynthesis. Similar to plants and algae, these bacteria use light as a source of energy to convert carbon dioxide and water into organic compounds, such as carbohydrates, while releasing oxygen as a byproduct.
Phototrophic Cyanobacteria: Cyanobacteria, also known as blue-green algae, are a group of bacteria that can perform oxygenic photosynthesis. They contain pigments called chlorophyll a and phycobilins, which enable them to capture light energy for photosynthesis.
Phototrophic Purple and Green Bacteria: These bacteria belong to the groups of Proteobacteria and Chlorobi, respectively. They use different pigments, such as bacteriochlorophylls and carotenoids, to capture light energy and carry out photosynthesis in specialized structures called chlorosomes.
