Cooperative cells provide fitness benefits to the entire population and have a higher productivity or yield in an exoproduct.
Non-cooperative cells have the lower productivity, but can exploit the benefits from the cooperative cells without contribution in mixed populations
Non-cooperative cells also have the higher productivity, but can exploit the benefits from the cooperative cells without contribution in mixed populations
