Today’s industries are increasingly reliant on the biological production of fuels, drugs, and other materials, bacteria among the foremost type of organism used. However bacterial production has its limits; large and complicated molecules impose a heavy metabolic burden on cells, and production is limited by the fitness cost, or the decreased health of the concerned organism.
These limitations can be circumnavigated by mimicking nature: getting two or more organisms to work together to produce one product.�One way of doing this is splitting the metabolic pathway between two cells.
