Bio-based photosynthetic conversion of CO2 and water to replace petroleum feedstock on an industrial scale
Strains of cyanobacteria that produce high levels of alpha ketoglutarate (AKG) and pyruvate are disclosed herein. Methods of culturing these cyanobacteria to produce AKG or pyruvate and recover AKG or pyruvate from the culture are also described herein. Nucleic acid sequences encoding polypeptides that function as ethylene-forming enzymes and their use in the production of ethylene are further disclosed herein. These nucleic acids may be expressed in hosts such as cyanobacteria, which in turn may be cultured to produce ethylene.
