  • Introduction: In a study conducted at KTH University in Sweden, they were able to produce refined cyanobacteria, carbon dioxide and sunlight, renewable butter, called butanol. In this paper, along with the production of co2 production plants, this laboratory is designed to grow cyanobacteria by modifying the genetic structure and producing butanol, It uses butanol for fuel for the power plant. One of the challenges facing humans is the increase in the heat of the earth due to the increase in greenhouse gases, especially CO2. I was studying the transfer of life to other planets using bacteria, a study conducted at KTH University in Sweden. The study, led by Paul Hedson, modified the genetic structure of cyanobacteria to alter the natural metabolism of these bacteria to produce butanol. By correcting the relevant genes in the cyanobacterial genome, they could deceive cyanobacteria. They produce butanol instead of their natural process. I have come to the conclusion that it will be built alongside with the laboratories producing CO2, In this laboratory , cyanobacteria are being cultivated with genetically modified structure using CO2 and sunlight and butanol production, and use butanol to generate electricity
  • Methods: In this article, it is explained that next to the factories that produce carbon dioxide, tanks are placed in which the carbon dioxide produced by these factories is placed. Next to these tanks, we place glass greenhouses containing large erlens containing genetically modified bacteria that produce butanel. It then transports the carbon dioxide in these tanks to large erlens, as well as sunlight, which is a growth factor for these bacteria and thus produces butanel. Then next to this glass greenhouse containing the large Erlenmeyer is a power plant that works with butanel, just like the power plants in Brazil that run on ethanol.
  • Results: As explained in the article, it can be concluded that using genetic modification of bacteria to reduce the amount of carbon dioxide on Earth and generate electricity from butane, which is a renewable fuel.In fact, with this method, we can significantly reduce greenhouse gases. Increasing greenhouse gases is one of the problems of climate change, which in this way not only reduces it but also generates electricity from the fuel produced.
  • Conclusion: In fact, this article explains that by modifying the genetic structure of cyanobacteria, we can link the natural metabolism of cyanobacteria to the production of butanel. In fact, by modifying the relevant genes in the genome of cyanobacteria, we can trick cyanobacteria into producing butanel instead of its natural process.The positive point of butanol is that its raw materials are found in abundance and are renewable, and also butanol can be obtained 20 times more than sugarcane or corn stalks.
