Perhaps in the near future, carbon-neutral products produced by solar energy, carbon dioxide and water can be used to replace fossil fuels. According to foreign media reports, scientists at Uppsala University in Sweden have successfully produced cyanobacteria (the most efficient photosynthetic organism on earth). This specially designed microorganism can use COâ‚‚ without using solar cells And solar energy to efficiently produce butanol.
Pia Lindberg, a senior lecturer in the chemistry department of the Angstrom Laboratory at Uppsala University, said: "We have systematically designed and created a series of improved cyanobacteria that can directly produce more and more butanol. When conducting long-term experiments with the best cells, we saw that their production exceeded the levels reported so far. Moreover, this process is comparable to an indirect process in which bacteria are fed sugar. "
In the past, we verified the concept and knew that it was possible to produce butanol by this method. Now, for the first time, researchers have adjusted it enough to make commercial applications possible. Researchers believe that carbon-neutral butanol can be used not only as a clean car fuel, but also as an environmentally friendly component of rubber, and as a way to significantly reduce carbon dioxide emissions in many large industries.
Professor Peter Lindblad of Uppsala ’s Department of Chemistry explained: “In this study, we used their [cyanobacteria] ability to effectively capture the energy of the sun and combine it with carbon dioxide in the air. Use all the tools to improve the cyanobacteria to produce the ideal product. "
The study at Uppsala University is part of the EU Photofuel project. The project is coordinated by Volkswagen and aims to develop new technologies for sustainable production of alternative fuels for use in the transportation sector.
