Enhanced stable production of ethylene in photosynthetic cyanobacterium Synechococcus elongatus PCC 7942.

ABSTRACT: Ethylene is a volatile alkene which is used in large commercial scale as a precursor in plastic industry, and is currently derived from petroleum refinement. As an alternative production strategy, photoautotrophic cyanobacteria Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942 have been previously evaluated as potential biotechnological hosts for producing ethylene directly from CO₂, by the over-expression of ethylene forming enzyme (efe) from Pseudomonas syringae. This work addresses various open questions related to the use of Synechococcus as the engineering target, and demonstrates long-term ethylene production at rates reaching 140 µL L^-1 h^-1 OD₇₅₀^-1 without loss of host vitality or capacity to produce ethylene.
