Research Team Advances:Liquid cyanobacteria culture is grown in Jianping Yu's lab at NREL to advance sustainable ethylene production.
For decades engineers have dreamed of programming organisms to sustainably produce ethylene, a chemical that is nicknamed “the king of petrochemicals” for its importance in plastics. Now, one hopeful pathway to this petrochemical is nearing reality, via a photosynthetic bacterium that is genetically specialized to turn sunlight and carbon dioxide into ethylene.
,” the researchers report their discovery and demonstration that a certain gene can induce stability in bacteria that produce ethylene. Their discovery is a welcome breakthrough, as past attempts at employing this ethylene pathway had led to genetic instability in the bacteria. “Our objective is to understand the source of guanidine toxicity in this pathway and how cells can thwart it. To that end, we now have a pretty compelling approach,” Yu said.
