Ancient Origin of Photosynthesis Gives Hint About Strange Bacteria
In photosynthesis, glucose is produced by using sunlight and through a chemical process. There are two types of photosynthesis. Anoxygenic and oxygenic photosynthesis. It is assumed that an-oxygenic photosynthesis occurred first. The oxygenic photosynthesis occurred in later. The oxygenic photosynthesis took a billion years to develop. In the anoxygenic process, bacteria do not use water. They only use molecules, and water is not released. In oxygenic photosynthesis, oxygen gets released as a waste product. The researchers from the Imperial College of London found new bacteria. These bacteria are similar to the current bacteria, that plays a key role in photosynthesis. The structure of this new bacteria matched with present cyanobacteria. These bacteria probably occur in soils and waterlogged fields in the hot springs. Today the cyanobacteria perform oxygenic photosynthesis.
The Cyanobacteria and new bacteria have a common site. This site split water during the process of photosynthesis. The evolution of the oxygenic photosynthesis is based on cyanobacteria. Also, the similar structure of these bacteria shows that both are borne from the same bacteria. There are many research studies available about photosynthesis evolution. Many of them are not supported by actual data sources. This research is expected to provide more details about photosynthesis and the production of oxygen. The complete research of it may change traditional concepts of the evolution of photosynthesis. The structure of newly observed bacteria also suggests that it is present from ancient times. This also suggests oxygenic photosynthesis is also developed shortly after anoxygenic photosynthesis.
The name of that bacteria, that researchers from Imperial College of London found is Heliobacterium modesticaldum. These bacteria are considered as rare bacteria. These bacteria are having the same ancestor as cyanobacteria had billion years ago. According to the traditional concept, anoxygenic photosynthesis developed first. This type was present for a billion years. The current findings may change this traditional concept. Furthermore, researchers observed that the Heliobacterium modesticaldum last had a common ancestor as cyanobacteria had billions of years ago.
