What is it about?

Photosynthetic cyanobacteria hold a great potential for the direct conversion of solar energy and CO2 into ‘green’ ethylene. The research article describes a method for engineering a thin-layer artificial biofilm technology capable of sustainable and long-term ethylene photoproduction.

Why is it important?

Ethylene is one of the most important and widely used organic chemicals, which is mainly produced via steam cracking of hydrocarbons. The process requires a significant supply of energy and leads to a huge release of CO2 into the atmosphere. In contrast, cyanobacteria could photosynthesize ethylene from atmospheric CO2 using sunlight as the only energy source.

Perspectives

This research opens up new possibilities for the further development of efficient solid-state photosynthetic cell factories for ethylene production and scaling up the process to the industrial level.
