Metabolic engineering and synthetic biology of cyanobacteria offer a promising sustainable alternative approach for fossil-based ethylene production， by using sunlight via oxygenic photosynthesis， to convert carbon dioxide directly into ethylene. Towards this， both well-studied cyanobacteria， i.e.， Synechocystis sp PCC 6803 and Synechococcus elongatus PCC 7942， have been engineered to produce ethylene by introducing the ethylene-forming enzyme (Efe) from Pseudomonas syringae pv. phaseolicola PK2 (the Kudzu strain)， which catalyzes the conversion of the ubiquitous tricarboxylic acid cycle intermediate 2-oxoglutarate into ethylene.
