查尔斯·米勒建议，尝试基因工程在光感大肠杆菌里基因物质，而不是在利用可以进行光合作用的蓝藻的基因的犹他州立大学代表队说，最终目标应该是制造以成本更低的疫苗和藻类为基础的“绿色”燃料，不像大肠杆菌那样，蓝藻只需要水和阳光的生存来源，而不是碳水化合物。
Miller says the ultimate goal is to make it cheaper to produce vaccines and algae-based "green" fuels. Unlike e. coli, cyanobacteria only need water and sunlight to survive instead of a carbon source.
