Currently, cyanobacteria is used to produce biofuel, however the process is costly and not as efficient. We will reengineer cyanobacteria to increase the efficiency of biofuel production by improving the collection of sunlight and the collection of biofuel. We will maximise the collection of sunlight by engineering a system in which cyanobacteria will be able to adjust its antenna length to the light intensity. Collection of biofuel will also become easier when we engineer cyanobacteria to lyse when optimal levels of inner fatty acids are sensed.
