Growth-coupled and salt-stress independent production of sucrose from CO2

CSIC has developed a procedure for capturing atmospheric CO2 into sugars by constructing and using a recombinant Synechococcus elongatus strain. The novel strain is able to overproduce sucrose coupled to growth in the absent of any environmental stress. Furthermore, the strain is able to maintain a very high sucrose production rate for a long time while exceeding titers previous reported by engineered cyanobacteria. The organic sugar produced can be further used for feeding any biotechnological process in the context of autotrophic/heterotrophic microbial consortia.

Industrial partners are being sought to collaborate through a patent licence agreement.
