Imagine a world where production of different compound could be easily achievable, where industrial problems associated with genetic manipulation are over: there is no more instability in the energy flux of bacteria. Imagine a world where there are no more industrial biosafety issues because recombinant bacteria is no longer needed in situ. This is the world we propose: the world of in vitro production. To achieve this, we reengineered the Carboxysome, a bacterial microcompartment (BMC) to use it as a continuous reactor capable of generating any output by having the needed enzyme in its inner space. Make Carboxysome your own synthetic space for the production of anything you want: A Whateversisome!
