  2. 16. Increased Carbon Fixation for Chemical Production in Cyanobacteria

    Author : Claudia Durall de la Fuente; Peter Lindblad; George Owttrim; Uppsala universitet; []
    Keywords : ;

    Abstract : The combustion of fossil fuels has created many environmental problems, the major one, the greenhouse effect. Thus, we need solutions in order to replace fossil fuels and recycle the CO2 in the atmosphere. Renewable energies have created attention the last decades but electricity is the main energy form obtained. READ MORE
