| Outline of Final Research Achievements |
To reduce the rate of global warming, we have developed a novel bio-ethylene synthetic process using the both cellulosomal system and cyanobacteria. In vivo synergistic effect of chimeric enzyme complex on ethylene production was demonstrated. In order to produce more bio-ethylene from cyanobacteria, the investigation was performed as follows. First, to produce ethylene from SAM via ACC in a concerted fashion with less inhibition of ACS, we have constructed two chimeric enzyme complexes, SOC3D1 and SOC3D2, based on cellulosomal system. Second, two chimeric enzyme complexes were introduced into Synechococcus elongatus PCC7942. Then, we have examined the in vivo ethylene accumulation of engineered S. elongatus PCC7942 cells to determine whether the expressed chimeric enzymes produce more ethylene.
