Discovery - Marine Bacteria Using Sunlight Absorb Carbon Dioxide

Marine bacteria have the capacity to take up and capture carbon dioxide with the help of sunlight, say researchers at Kalmar University in Sweden in collaboration with colleagues in Spain, Australia, and Russia. This can be compared to a simple form of photosynthesis, where marine bacteria use energy from sunlight to absorb carbon dioxide. It was previously known that bacteria in oxygen-starved lakes can have this capacity, but it's new knowledge that bacteria in the open seas can do so as well. This challenges earlier knowledge that algae are the only organisms that capture carbon dioxide in the surface water exposed to sunlight. It remains unknown just how much carbon dioxide is captured by these bacteria. read more
