Researchers show off fuel production with cyanobacteria

According to foreign media reports, researchers from the KTH Royal Institute of Technology recently produced butanol from blue-green baths, sunlight, carbon dioxide, and bacteria. The substance is a carbohydrate that can be used as a fuel for motor vehicles.
Butanol, which can be used as an energy source, has great advantages because it is rich in raw materials and can be regenerated, and the yield potential of butanol is enormous, about 20 times more efficient than producing ethanol from corn and sucrose.
According to the researchers, they used genetically modified cyanobacteria to combine the production of butanol with the natural metabolic mechanisms of bacteria, integrate the relevant genes into the correct part of the cyanobacterial genome, and modify the cells into secreted cyanobacteria. Instead of perfecting their normal mechanisms, alcohols.
After many experiments, the researchers demonstrated that butanol production can be controlled by changing the environment around cyanobacteria. Paul Hudson, head of research, said that this would facilitate better control of butanol production and could be produced within a specified time of day. However, it will take ten years for the technology to become popular and reach commercial use.
He added: “We are very happy to be able to produce biofuels from cyanobacteria. At the same time, we must remember that this production process is totally different from the current biofuel production methods.â€
A leading Swedish biotechnology researcher said that the use of engineering technology to modify the genome of microorganisms is still a relatively new field. The technology that bacteria use sunlight and dioxin carbon to produce cheap energy may change the world. (Shang Li)
