To stay competitive, industries need to increase their productivity. Typically this is done by improving the process of manufacturing, the factory efficiency. Synthetic biology is no different. Natalia Kakko, a doctoral student at the Center for Young Synbio Scientists, is working on the vital task of streamlining the productivity of cells. Improving “cellular factories,” could enable many synthetic biology-based companies to be more productive and more profitable, as well as support several UN sustainable development goals.
